I just looked at the replacement bowl setups from Ranch Hand Supply and they show two different styles. You can see them here: Jinma Fuel Sediment Bowl Also checked an online parts catalog and they list two different styles, one with a straight thread (metric) using a jam nut and seal and one...

My fuel tank had a 1/4" NPT fitting on the bottom of the tank. The original bowl had a threaded nipple on the top that screwed directly into the tank. The replacement from Ranch Hand (second photo) also had the nipple on the top but I took the opportunity to use a couple of elbows to offset the...

The OEM fuel bowl on my 2006 284 had a plastic bowl that quickly clouded and was difficult to monitor the contents. I bought one with a glass bowl from Ranch Hand Supply. Still crystal clear all these years later. I did discover that the OEM fuel line with the banjo fittings is close enough to...

Yup, agreed with the other responses. It is very unusual for the manufacturer to use two different castings for this kind of production. It is understandable that the newer ones might be of higher quality and look nicer. I would take all 3 to a machine shop and ask if they can make either one...

It is hard to know what else went wrong without getting a look inside. The access port is a cover on the bell housing just in front of the clutch pedal. If you have a front end loader this cover is removed and the mounting bracket bolts on in its place. You have to either remove the FEL so you...

If you have the service manual, check to see if there is a chart of standard torque values. These are used for anywhere a specific value is not listed. Not all manuals have that information so you have to rely on torque tables from other sources. I usually try to check 2 or 3 different ones to...

If my math is correct the 284 Y385 engine is about 2.5L. At 2800 RPM it would be sucking in about 125 cubic feet of air per minute, give or take a little.

For what it is worth: After 15 years and 860 hours I have never had an overheat that was caused by the air cleaner in front of the radiator and the canister has never collected enough dust to come out the squeeze vent at the bottom of the canister. I have only had to replace the filter a couple...

Donaldson P148969 fits my factory 2006 Jinma 284 filter canister perfectly. Also WIX 42276

Those were mentioned on a machining forum I frequent but I hadn't looked into them. Ingenious little buggers and priced accordingly! The statement that they work on tension not friction is a little misleading. Yes you have to increase tension to override the cam and loosen the bolt, BUT it...

"Some" bolts are designed to stretch a certain amount as the final torque is set. Usually these are one time use only bolts (or studs in some applications). Once this bolt has been torqued to final spec it is "used" and even if you did it two minutes ago and have to take it out to do something...

Very good Danica! Glad you are back to tractoring and done with the fixing. :) I think in this instance the temp gauge could be thought of a "fuel use" gauge. It takes a certain amount of fuel to warm your engine up to a particular reading and it took that much fuel use to draw in enough air to...

Very good that you got to the bottom of it. Care to add any details like where the air was getting in and what you had to do to stop it?

You could always recycle it yourself. With the proper application of heat all the elements that make up the tire will return to their place of origin. Just say'n.....

do you have any pictures?

As for oil in coolant or the other way around, a good option is to have a lab test samples of each. They can detect cross contamination as well as exhaust residue or fuel in either fluid. One of the places I worked had it's own in house lab. We sold the sample bottles, two varieties of each...

Speaking of lift pumps, does your tractor have a hand primer pump? This is usually a knob that turns to loosen, then the spring pushes it up. You open a bleeder screw or crack a fuel line, unscrew the knob and then pump in and out with the plunger to purge any air trapped in the system. If you...

Yup, but too many owners see salesmen as money makers and parts and service people as expenses. But that is a totally different discussion. I was only trying to show the "other side of the counter". To the OP, None of my ranting was pointed at you as I believe you found a truly bad dealer, best...

Exactly! I don't know about all manufacturers but the ones I dealt with were terrible at the most simple and common parts. Shame on them. Even my 25 year old el-cheapo garden tractor has a sticker under the hood that lists the OEM part numbers for the filters, belts and mower blades. A 50 cent...

One last story: Guy comes in and sits down in front of the top counterman and says he needs such and such shaft for his XYZ baler model 123. Not in stock so ordered from manufacturer as we are a dealer for XYZ. Part comes in, picked up and paid for. Returns it to me and says it is the wrong...

Yup. I spent many more years in IT support than at the parts counter. I bought a new computer and let my kid use it, now it is full of viruses, how much to fix. Aprox $500 worth of time. What? I didn't pay that much for the PC< you're ripping me off. Fix it yourself... PICNIC (problem in chair...

Where I worked a typical call from a large customer would be: This is Jack from XYZ, I need a hydraulic filter for unit #17 Put customer name and unit number in system. Pull up details about "as shipped" and transfer S/N to parts look up screen. Compare multitude of choices and narrow down to...

I'll inject a slightly different point of view here, from a parts counter perspective. I have experience in both auto and equipment parts. If the counterman asked if you bought the machine from them it was likely an effort to get exactly the right information to assist in looking up parts. You...

Yup, that is what I did, except I couldn't find anything local that had a screen so used the paper filter element instead.

The metal screen in my 2006 Jinma 284 was very fragile and I tore a hole in it the first time I tried to clean it. Desperate for something to use I found a paper filter that I could rig up to fit the suction pipe from the original screen. It had way more surface area than the screen but it was...

Danica, You said that the problem starts as the temp reaches the mid-point on the temp gauge on the dash. Working on the assumption that the sender and gauge are correct, it is not likely that you have an overheating issue. Before you get too far down the overheating rabbit hole, it might be...

Ag tires are designed to get the most traction when there is a specific amount of "slip" between the dirt and the tire. In other words the tire has to be traveling slightly faster than the tractor. Usually this is in the 5 to 8 percent range and you can actually see it in the dirt profile when...

The braided hoses at the sediment bowl, one from the tank and the other out to the lift pump or main fuel filter? Simple enough... Where does the non-braided line come from/go to? Without seeing the whole system, I would guess it is a return line from the injectors or injector pump? The...

This has been a very interesting thread to follow. I have heard of hydraulic lines that de-laminate internally, causing all kinds of issues. Sometimes a piece can come loose and "flap" over a fitting partially or completely blocking the line. Other times they can "balloon" out with the same...

What kind of tires do you have now? Ag, Turf, Industrial? What is the condition of your current tires, new or worn out? Are your tires spinning/slipping in the dirt? What task are you doing that you don't have enough traction for? IF you are spinning on dry dirt and you swap for the same...

When I put this mix in anything but a sealed metal container the acetone always escapes over time so I have never tried it in an oil can. Most of my oil cans leak a little around the threads or piston hole so they probably won't hold acetone. Mixing small batches as I need it seems to work best...

80W-90 in one because it is convenient for changing fluid in the bike's rear end. I have a drain tray that lets you put empty oil bottles in the top and screw one on the drain at the bottom. You only get a few drops from each bottle but with all the oils I use the collection bottle seems to...

Would it be possible to just grind a little bit off of the top corner of the latch so that the busing will slip out? That seems to be the only thing that is making it hard to disconnect. Leave the bottom portion as is and it should still hold fine when in the locked position.

It wasn't really that hard. I had to use a front end loader at a nearby business to get the crates off of the semi-trailer and onto my trailer. I put the backhoe in the pickup box, the FEL on the front of my car trailer and the tractor on the back. Backed into the garage and dropped the ramps in...

Copperheads are way after my time. Cool ordinance though... 13E here. Shot, Over...

Yeah, our old FADAC computers (from the 1950's) required 400 Hz. Everything else used standard single phase 60Hz. Every unit had to pack around two generators. The Military Way! Interestingly enough, the same computers were used in the classroom via some kind of inverter, which apparently...

Domestic hogs sometimes escape and can't be found. If conditions are right (at least a breeding pair and weather), there you go, feral population! Most escaped pigs don't survive the winters here, and those that do are usually taken care of by the landowners or hunters. The one county in ND...

15 years ago I bought a new tractor in a crate complete with FEL and backhoe. $13K delivered to my door. First task, move snow (my old tractor had developed major problems). Second task, dig in new septic system. Backhoe paid for itself in one job. It has done many more since then. 15 years...

Did you attempt to engage the starter while the wires were crossed? If not, there should be no damage caused to the solenoid or the starter from the crossed wires but the battery, cables, alternator and possibly a fuse or two might have suffered. Since you are getting a clicking at the...

IMO DR products are highly over priced for their quality. Shows what a good advertising campaign can do. For 400' of gravel driveway I made this from salvaged road grader cutting edges. It is UGLY and heavy but it does the job when I need it to. Because both blades angle the same direction I...

Thanks Bob, From what I can tell the DP20 only reads Hz up to 100. If I used a 60 tooth trigger (one pulse per second @ 1 RPM) it would display as a direct RPM number but would only work up to 100 RPM. Any trigger tooth count other than 60 would require a conversion factor to RPM, which I...

Circle G. They have both sizes in stock.

Got the correct part in today's mail. Tested with VOM on A/C volts and could see voltage using the drill chuck as a trigger. Installed on tractor and the tach now works! With the engine idling it was showing about 27 volts on the leads so it is a significant little generator. Now all I have to...

Everybody has different sized operations and needs. Personally I just unloaded and stacked 300 55# alfalfa bales by hand yesterday. We don't have the storage space or the equipment to handle anything but small squares. We also made 20 bales of ditch grass hay (mostly brome) with an hand powered...

Very good info. Thanks for posting the follow ups. You are adding to the public knowledge base. Good to hear that taking the axle out was that easy. I was looking at mine the other day and wondering if it would be easier to do that or drain the coolant and pop the radiator off to get to the top...

This is a great thread because it shows that not everyone is at the same level and things that so many of us just take for granted are all things we had to learn at some point. Some of those things were learned many decades ago and some were learned only today. Just depends on when you started...

Good news, bad news, more good news, more bad news. Sensor arrived a day earlier than expected and I had time to fiddle with it this afternoon. I ordered an 18mm sensor when I should have ordered the 15.5 (16) mm one. I didn't see that option when I ordered the first one. Went at the search...

Thanks for the link Bob. Good info indeed. I find it interesting that Jinma chose to mount the sensor 90 degrees to the ring gear instead of in line with the teeth as shown by Murphy. The Jinma method would seem less effective and is prone to issues caused by any run out at the ring gear. I'm...

Yeah, I figured it was a reluctor. They have a coil inside so I thought there should be some resistance. I even have a listing where someone had measured it and got a little resistance, not just open. The information I found said either 1/2 turn or 3/4 turn back out after contact. I split the...

Correct. A loop really messes things up if fluid gets in it. In my case the pump is below the engine so it is possible for crankcase fumes (2 stroke) to condense in the line and flow to the pump. The weep hole at the bottom of the pump takes care of that and the fuel tank is below the pump so it...

2006 Jinma 284 with Y385 engine. All working fine on a rather warm day. Shut down for a cold drink and re-fuel. When started back up tach was dead. No flaky behavior prior to this, working one minute and dead the next. All other instruments working. Looking at a wiring diagram it appears that...

If the fuel pump is like what Rotax uses on some engines it is a diaphragm with fuel on one side and engine vacuum pulses on the other side. In the case of Rotax, the pulse line is connected to the crankcase and the piston moving up and down causes the pulsing which causes the diaphragm to move...

If an axle shaft is broken cleanly then the unbroken wheel would likely spin if it were jacked up and free to do so, but the moment you put a load on that wheel it would stop and all the input power would just go to the broken axle. Two things I can think of that would cause one wheel to have...

In 4wd and in gear and only one front tire in the air, nothing should turn. If both front tires are in the air, rotating one should make the other one turn the other direction and the drive shaft should not turn. The driveshaft does not use a cross type U-joint but rather a CV type using a...

With the engine off and the tractor in gear and in 4WD, jack up one front wheel and try to spin it by hand. It should not turn. If it does turn, does the front drive shaft turn? With the engine off and the tractor in gear and in 4WD, with all 4 wheels on the ground, can you turn the front drive...

Double speed increase pulleys. How fast do the fans turn at full PTO speed? Would it be close enough you can run it with the engine from your other unit? To replace the coupler you could flip the pulleys on the jack shaft to decrease engine RPM, then flip the pulleys at the fan end to bring it...

sd455dan, interesting that you saw a difference in output on the higher voltage. I had 240 plug already in place and never tried it on 120. Maybe that is why I was so impressed with it first time out. :) I know it will slice through 5/8' high carbon cutting edges with no problems if you don't...

My Lotos came without specific wiring but was capable of 120 or 240. I chose 240 and made up a locking plug pigtail that let me plug it into the same outlet my AC/DC welder used. There was no specific instructions for different consumables with different voltages. I thing the transformer just...

Because not all plasma conduits are the same size. Sometimes you have to cut the plasma down to fit. Just like sending the smaller people into the Jeffries tubes..... I have the Lotos with the pilot arc but don't remember the model number off the top of my head. A little bit of a learning curve...

a quick online search shows several sources for a replacement if you can't get this one to work. Search DKJ1308 solenoid. After you get a new one on and working you won't have to be timid about taking this one apart. :D

Can you read any numbers off of the old belt? Might get a clue from that. Sometimes the number is the actual width and length dimensions. Another idea is to make a mark on the belt and then use a flexible tape measure, measure and mark, turn the pulley, repeat until you get to the starting mark...

The only filter information I have is for the TY380 and TY385 engines that both used the original Jinma part number JXD706P, It was listed as having 20mm threads, no other specs. Filters that cross reference to that number are: NAPA 1626 or FIL1381 Fram PH3935 or PH3985 AC (Delco) PF970C WIX...

I'm not so sure. He stated that he jumped from the positive of the battery to the small terminal on the solenoid and it worked. That would bypass the key switch and associated wires but the positive battery cable would still be in play. IF he had jumped from the battery to the LARGE terminal on...

Absolutely put an ohm meter on the cables. From the ground at the frame to the battery terminal. From the positive at the solenoid to the battery terminal. From the small connector on the solenoid to the terminal on the key switch. You should be seeing VERY low to no ohms of resistance depending...

Bob, That thought had crossed my mind too. What if he just connected power to the motor (bypassing the solenoid) and missed testing half of the system? Perhaps somewhere in this story there is "a failure to communicate". Or, we both were using English but weren't talking the same language. Hope...

The small terminal should only have voltage when the key is in start.he large terminal connected to the battery cable should always show battery voltage The large terminal that connects to the starter should only show voltage when the solenoid engages Connect a test light to the small wire at...

The ammeter also gives you another clue. When you turn the key you should see a slight movement toward discharge. This will be the current that the solenoid is drawing. If the solenoid is stuck it will draw current but not click. If the solenoid is burned out it will not click and not draw any...

Yes, I too suspect your battery is at least low. You started it from the battery but operating the tractor with the key in the off position most likely kept the alternator from recharging the battery. Technically a good battery should be able to make several starts in warm weather, but if it...

If your problem is random and self correcting it is not likely to be bad wiring as that will not get better on its own. However loose connections can act like this and a faulty key switch can be intermittent. The key switch usually fails at the glow plug contacts because that draws much more...

Yes, you are on the right track. Jump from the battery cable at the solenoid end to the small terminal on the solenoid. This will bypass the key switch and all the associated circuitry. If it still just clicks, the problem is in the solenoid. If it spins over, your problem lies elsewhere...

I took it as he jumped the terminals at the starter, ie: shorted them together. If he used another power source to jump to the starter then all bets are off. If the key switch or wiring are bad it could result in low voltage to the starter solenoid which would cause it to click but not provide...

If jumping the terminals on the starter works, your cables and connections from the battery are fine. The problem lies between the start position on the key switch and the starter. Trace that circuit and you will most likely find the problem. Do you have a wiring diagram for your tractor...

Check page 40 of the first document on my web page found here: Harnerfarm Jinma 284 Feel free to download any of these documents for your use.

I bought my tractor from them. Great service and parts, back in 2007. Then personnel changed and I never got the correct parts from them again. Some orders had to be placed multiple times. Never did find anyone that understood the hydraulic fittings or the light bulbs. Sad to say, but I moved...

Sounds like a stuck fuel cut off rack. Have you cracked a connection at the injector to make sure the pump is or is not pushing fuel?

does this image help any?

That's good work TTTTTT. No reason to change to anything else. The only limiting factor I can see is when rolled forward the lynch pins are taking all the load in shear. As long as you use good pins and don't exceed whatever sheer strength they have it is a nice simple setup.

In the absence of a good parts diagram about all that is left is take it apart to see how it works. The other side of that coin is "don't fix what ain't broke" If you do take it apart, it would be nice to see pictures.

curious if the one pin and the two pin setups use the same top bracket? where is the single pin located? If on center it could interfere with the cylinder rod so my idea of just drilling a third hole or adding two more pins would not work.

Very interesting. If it works, no need to mess with it. I wonder if you could fab up some kind of adapter that would let you use your single pin attachments without messing with the setup as it is?

That looks homemade to me. Based on the fact that the bracket hits the cross-tube and has actually damaged it. It is possible to be factory or after market but not likely without at least a small cutout to clear the cross-tube. There should be some kind of stop or the end of the cylinder travel...

The grease every 10 hours guideline is just a guide. It usually means hours of loader use, not tractor use. Also it does not consider what you are doing with the loader. Moving snow is a whole lot different than working in mud and sand on the edge of the creek. After a while you will get enough...

Ha! There was a picture in my files that actually shows a better view than taking a new one. The red circle is the main PTO engage lever and the yellow circle is the speed select lever

For some reason there aren't any diagrams for the Foton on the Circle G site. However taking a leap of faith that it is the same as the Jinma 254 you can find diagrams for that. If you look under Drive Gearbox there are two images. The main engage lever is shown on the first image and the two...

It is probably down low on the right side of the transmission near your right foot. It moves up and down. Down is engaged, up is free. It does not move very far. I don't have pictured to post but can take one if needed. Also you might look at the online parts catalog for your tractor. You can...

Just checked my Jinma. Pulled the vent tube and couldn't see much down inside the cover. Put a straight piece of wire in it and it went all the way to the bottom of the transmission housing. It would appear that the shaft for the low range is held in that boss. If it has a fork that extends...

That is interesting. On my tractor the vent behind the seat is for the hydraulics tank which is part of the 3 point lift assembly and what the seat frame actually bolts to. Is the oil level under the plug at the level as the transmission oil on the dipstick? In other words are you looking all...

That is probably a vent. Have you had the plug out to see if it has a filter on the inside and a small hole somewhere? The Jinma 284 that I have uses an inverted "U" pipe as a vent on that particular casting boss. It is a little more to the left where yours is centered but it is definitely a...

Is the purpose of putting used engine oil into the fuel just to dispose of the used oil? I can't imagine that introducing any contaminants to the fuel system can be good for it. Seems like really excessive oil and fluid change intervals. Rather than spend the $$$ (and time) on all those oil...

"coolant filter" and "water in the fuel lines" are two things that don't go together. It sounds like a miss-communication of some kind. Definitely need clarification for any kind of troubleshooting. The only thing that I can think of is some fuel filters have either a water separator or a...

Yup, cleaning and lubing the starter is just routine maintenance. I do it whenever the starter "seems weak".

If this had happened to me I would have said "Oops" & looked around to see if there are any witnesses and put it back together. Then grabbed the wrench from the tractor tool box and snugged the lock nut. It is there because I adjust the links a lot during tractor use, depending on what I am...

You would think that with the sending unit port open to air the pump would be pouring oil out no mater what the condition of the bearings were. Since there is no restriction it would be the path of least resistance and most all of the pumps output would come out there. If you still have the old...

What weight of oil are you using? What kind of pressures are you seeing? Does it stay the same or increase with engine speed? IF you can find the bearing clearance specs, Plasti-Gage is your friend Can you tell if you are getting oil circulation up through the valve train? IF the engine sounds...

The symptoms you described are the same as I had, although there was no grey muck in mine, just dirt and brush powder. The real culprit was the binding caused by dry bushings. A little white lith. grease took care of that. The tolerances are not too critical in this application but a dry bushing...

Sounds like you got it. Just clean everything, blow the dust out of the windings, etc. Then if it moves, lube it. Make sure all the electrical and mounting bolt points are clean and shiny metal to metal contact. It is just an ongoing maintenance thing.

What is an inspection or smog check? ;) Seriously, I know what they are, but in my state we used to have so called "safety inspections" which were little more than a scam. The citizens rose up and got that baloney tossed to the curb. Lived in a state once that required emissions testing. Moved...

As a customer: Rule #1 is never beg anyone to take my money. Rule #2 is never believe a salesman, know your stuff before you get that far. If you don't know, how do you know that they know? Ya Know? :)

Does the frequency change with the engine RPM? A quick and easy trick is to take the fan belt loose from the crank pulley as part of the process of elimination. In ancient times we used to put belt dressing on squeaking belts. Don't know if you can even buy it anymore.... You can also use a...

Having been in the IT business for most of my adult life I understand re-furbing PC's and re-using as much as possible because I am cheap. I also understand that you can't afford to pay someone else to do it if they are charging a reasonable rate because it is time consuming. Dumping a linux...

The problem with a 3Pt blade is there is no down pressure available. Also it is close to the rear axle and is subject to "cutting or dropping" material every time your front tires go over a bump or into a dip. If you run back and forth over the same spots pretty soon you have a roller coaster...

Thanks for posting the update. Good job! Does the cap separate from the cylinder? Does the o-ring seal between the cap and the cylinder or the cap and the housing? Did you have to remove the top of the transmission for clearance? Post pictures if you can.

Well, that raises some questions. The parts books show the cylinder and the cap being two different parts but the photos from that post show it coming out as one piece. Is yours leaking between the cap and the tank or is it leaking around the adjuster screw and just running down the cap? There...

It would appear that there is an o-ring that seals the cylinder to the valve housing but there is nothing shown between the housing (called a cap) and the tank body. One would think that there needs to be a gasket between them. Have you completely removed the adjusting knob and associated parts...

beware of "diesel bugs". Sounds like you might be infected. Cleaning screens and replacing filters is only a stop gap measure until you get the entire system purged, cleaned and sanitized of water. At the very least, get a bottle of biocide and start treatment right away.

I thought I had a better picture of the top link support but I can't find it. The frame and wheels are the start of a cart to store the backhoe on. It sure makes moving it in and out of storage a lot easier to have wheels under it!

Interesting. The Jinma backhoe I have is a full frame mount which ties to the lower 3 point pins and the loader mount. I added a bracket that also ties to the top link mount. The reason was that the lower ladder frame had a tendency to break at the mounting slots, This one came with a beefed up...

Some quick poking around the internet shows that this is a fairly old and obsolete tractor. Connected to Mahindra somehow in the past but others report they can not get parts or service from anyone. Used is probably your only option in the US but there are over seas sites that sell parts for...

Since you have already gone to the work of doing the conversion and you know that the OEM is prone to failure, I would leave it as is. Put the new one on the shelf as a backup. Odds are you will never need it. The mechanical pump on my Jinma used an O-ring to seal a sliding shaft instead of a...

Are you able to tell what side the squeak is coming from? You might try taking a tie rod end off of one of the steering knuckles. Then with the front wheels jacked off the ground just turn the wheels by hand, one at a time and see if that helps isolate the noise. Just a process of elimination...

Also with both front wheels off the ground you can turn the steering wheel with the engine off and the wheels should turn left and right. Without the extra noise of the engine it should be easier to hear where the squeak is coming from. I'm not sure about the zerk you are referring to as the...

The farm and home store I work at is having problems getting a lot of products. The automotive manager told me this week that he can't get most oil that he orders. Some house brand stuff but most of the name brand stuff just goes to back order. In other parts of the store what we get is really...

This is good news. The spring is on the far opposite side of the sliding shaft and is held on with a nut so I doubt that if anything was broken it would be able to push the shaft out. But then again that might depend on where and how it is broken. Most likely it has not pushed out quite far...

The rounded over "button" you see is actually the head of the bolt. That bolt is threaded into the end of the shaft that connects to the shift fork inside. In normal operation the shaft is pushed out towards the lever by an internal spring. This holds the locking jaws apart and allows the...

Some digging revealed that the return line is all one piece from the injector pump, to the daisy chain on the injectors to the fitting for the tank. See it here: Y385T-6-10400 (Fuel return line across each injector) | Jinma Tractor Parts, Farm Pro Tractor Parts | Circle G Tractor Parts. It is...

Have you checked with a Jinma dealer? There are several good ones online. Ranchhandsupply is probably nearest to you. Also Affordabletractor and circlegtractor come to mind. You may have to buy an entire end plate to get a new bushing. What engine do you have? The dealer will need to know. Most...

That is the return line from the fuel system to the tank, it won't have much pressure on it while in use and can easily be changed out as long as the fuel level in the tank is below the fitting level. It should be easy enough to get a replacement hose from any Jinma dealer, but you can also cut...

Yes, please post pictures. To track down leaks I usually try to get everything clean and dry so that you have a better chance of seeing the source instead of the results. I would use a spray brake cleaner to wash down the suspected fuel leak area. O-rings in fuel fittings and rubber radiator...

An additional thought: Use a mirror or digital camera to get a look at the inside of the nipple that the fuel filter screws onto. Is it rusty inside? If not, the water maybe didn't get past the filter.

All that rust indicates water in the system and for a long time too. If the filter looks like that, imagine what the inside of the tank and injector pump look like. The injectors might be junk too. I would get the tank out and see if it is salvageable. Hopefully you didn't get an infestation of...

It seems that every diesel engine has its own little idiosyncrasies particularly when it comes to starting. My tractor for example needs a little glow plug help even up to about +70 degrees, at least on the first start of the day. I usually start at about 1/4 throttle and then idle down to 1000...

I'm not aware of Jinma ever publishing a service manual like we are used to seeing for vehicles. They usually only have a parts manual/book and an operators manual which will include things like scheduled service procedures. Things like re-torque of head bolts or adjustment of clutch. Check...

Looking good Bob. Now let's see it roll up a 4' high windrow of leaves. :)

That sounds almost exactly like my Jinma 284. On mine there is a 18X2.65 o-ring where the strainer tube screws into the bottom of the 3 bolt adapter plate on the top of the reservoir. This is inside the tank but above the fluid line. If that dip tube going down to the brass screen is loose or...

You are correct in thinking it is probably a suction side issue. All of the seals in the system get old and brittle with time and use. Could be an o-ring at either end of the hard line or where the adapter mounts to the pump. The pump itself has seals between the body and the end plates that can...

Looking good Bob. Question: Do you think the intake openings are big enough to supply full flow through the output opening, or will you be restricting that down some to get higher velocity?

That's too bad, and a lot of work to get to the oil pump. Maybe that is why the design changed later on. At least now you know. Best of luck getting it fixed and please do post an update when you do find what caused the loss of pressure.

That is a pretty good find Bob. I have an overstock of projects from good finds, most are in my someday pile, some are in the just in case I need it pile. First glace it looked like a snowblower fan assembly, but I've never seen one made that way. Then I thought it must have been for moving air...

Looking at my 2006 engine, the drawing in the parts book that came with it is not quite accurate either. It would appear that mine has a "pan" that is actually more like a lower end of the block as it appears to be where the engine mounts on the frame of the tractor. The bottom cover plate is...

That parts diagram looks like the one in my book except for the gasket between the block and the bell housing and the bell housing machined face. Mine was a 2006 model. Now I will have to go out and have a closer look in the morning when it gets light out. I've never had a reason to give that...

Do you have a parts manual for the engine? If not, have a look at the online parts diagrams at a dealer like Circle G or Affordable. They will give you an exploded view of how things go together. Looking at my manual it would appear there are multiple points of failure that could cause the pump...

Are you talking about the stand-alone tach/hour meter that is not part of the newer style integrated instrument clusters? Do you not have the existing sensor and tach? I have schematics for both styles but they do not show pin-outs at the instruments, only generic wire paths. they show the...

My parts book shows an O-ring on that threaded shaft size is 17X2.65 Part number GB3452.1-1992 I should probably replace mine too as it is seeping a little these days.

The comment about raising the boiling point was from memory of reading the chart on a jug of anti-freeze, admittedly many years ago. I just did a quick search and the Wikipedia entry backs that up. However, I did not know about the resulting loss of specific heat capacity. At first impulse it...

White smoke is usually an indication of either an engine running cold or an engine that is getting water into the combustion chamber. From your answers above my best guess at this point is a bad head gasket or a cracked head that is letting coolant (water) into one of the cylinders. This causes...

Hi Bob, I didn't see your post until I sent mine. We must have been typing at the same time. 😆 My initial thought was soot spit but then the picture of the broken exhaust sort of looks like oil. Some things can't be done by tele-medicine....

Exhaust systems that are exposed to rain (no cap) will spit black rain on startup, but usually quit in a few seconds. When the water evaporates you are left with black soot smudges everywhere. (ask me how I know...) I can't think of a situation where an oil galley in the head would be next to...

Other causes that come to mind are bad valve seals or stuck/broken/worn out piston rings. Have you changed the engine oil? If not I would try that first. If you have done that already I would consider an old school method of filling the crank case with diesel fuel, lock the fuel cut off to OFF...

Just a little north and west of Slowpoke Jim and I can confirm his description of our winters. I have a 2006 Jinma 284 and have plowed snow when it was blowing 30+ MPH and -22F. (neighbors plow broke down so I bailed him out). There were times when the hydraulic fluid would get so cold I could...

Both front axles of my 284 developed leaks. Seals were fairly easy to obtain, at least several years ago. On the 284 there is a felt washer that is supposed to keep dust and debris from getting to the actual seal. The felt disintegrated and then dirt got in the seal, wiped out the seal and left...

Connectors and crimpers come in both good quality and poor quality. Getting the good stuff and and using the proper technique is the other side of the choose the proper location coin. Solder provides the superior electrical connection, but it can lead to broken wires at the end of the solder...

That is some ugly stuff right there... Go to your friendly local automotive parts store and pick a style of connector you like. Weatherproof preferred but may not be an option. In any case di-electric grease is your friend on re-assembly. Also either Bo-shield (sp?) or ACF-50 are great products...

Turn signal wiring can be, shall we say Messy. Lots of different ways to do it. You can find some of them laid out here: turn signal flasher wiring schematic at DuckDuckGo Do your brake lights and turn signals share the same filament in the rear bulb like they do in American made cars or are...

If the bulbs involved have more than one filament you should remove the bulb for testing. The filaments likely have a common ground and therefore can "backfeed" from one conductor to another. In other words, there is your short. Even a bulb on the other side of the tractor can cause this if they...

The knob under the seat only controls how fast the 3 point lowers. The 3 point is a single acting cylinder that is powered after the loader and after the power steering. The pressure relief valve for the steering and 3 point is in the 2 point control valve. Your loader control valve may or may...

What you are describing is a leak down issue. The bucket leaks down all the way but the loader arms only leak down halfway. The two things that can cause this that I know of are internal cylinder leakage (from one side of the piston to the other) or an internal leak in the control valve where...

Some questions: Are you saying that while the bucket is uncurling (dumping) the loader also lowers to midpoint un-commanded (no up or down movement at the joystick)? Can you raise and lower the loader completely without rolling the bucket? Were both lift cylinders rebuilt? Are you able to raise...

Ha! I just got a new catalog with an order last week but haven't had time to flip through it yet. I may have a drive pulley under a bench in the shop. Bought it many years ago because it was supposed to fit my Allis Chalmers WD. It didn't, so got shoved aside somewhere. It could be doable with...

Anyone ever see or use a flat belt pulley setup on a Jinma 200 series? My parts book has all the parts shown but it really doesn't show where it goes on the tractor. It looks like it mounts over the PTO shaft, is that correct? I've got a couple of old grain mills with flat belt pulleys on them...

About the only thing left is to check the pressure relief valve. If it failed it could be dumping at a lower pressure than it is supposed to. If you look into the tank through the filler plug while the engine is running can you see movement of the fluid? how about if you turn the steering wheel...

Another idea I have noodled on is an auxiliary tank plumbed in parallel to increase total capacity. I guess I could fix one up and use the return quick connect for an easy test.

It is more of an over sized and extended breather tube but I can believe that duct tape is the answer I just need to figure out how to apply it. Keep yer stick on the ice!

My tractor does a lot of stacking of stuff. Snow (most winters), manure and sometimes dirt or brush. Since I don't have a lot of area the piles need to go up rather than out. As the piles get higher than about 6 or 8 feet I run into the issue of running out of hydraulic fluid. The loader...

It just dawned on me the proper way to handle the sender screws being too short is to clean the tank flange threads really good and then install some studs with thread locker. Then the sender could be installed with washers, locks and nuts. Unfortunately I didn't have anything on hand to even...

Next problem was finding a flat spot on the dash that would accommodate the new gauge. This is close to flat and acceptable. Then there was the wiring issues. The harness is short enough that when I moved the panel for access about half the wires for my switches pulled off. After finding a bad...

To correct this problem I decided to make eggs out of the holes on the new sender. A little hand work with a round file and soon it was doable. Ugly and not the preferred fix but without a lathe or milling machine this was the best I could do. Fortunately the new sender had a thick enough and...

OK, it is in and working. What an ugly project that turned out to be. But I sort of expected that. Here is a link to the sender/gauge combo I used: FUEL TANK GAUGE METER SENDER 8" STAINLESS WEMA KUS UPFR-BB-240-33 BLACK GAS 8 " | eBay First off, the new setup was just fine. The big problem I...

Ouch! Something bad happened there. I've got 800 hours on my 2006 284, most of it 4X4 and some if kind of harsh with no issues except some leaking seals. Take a look here: Harnerfarm Jinma 284 the file labeled operation manual has some good info in it even if it is a little hard to follow. I...

That is a really ugly way to mount the valve to the cylinder. Not only does it rely on tapered fittings lining up properly it is the sole support for the valve. Getting the valve in the proper position without over/under tight on one side or the other is difficult plus vibration is your enemy of...

There is a single steel strap that runs from side to side. There was a rubber sleeve for the strap but nothing for under the tank. Also the tank mounting plate bolts directly to the bracket that sets down over the steering box. In this picture you can kind of see the ribbed matting that is under...

The OP said it wasn't going into the hydraulic system but going into the transmission. Besides, the hydraulic pump input shaft isn't submersed in engine oil so that scenario is unlikely. This is one that I would really like to see for myself. None of it seems logical unless someone did something...

Does the transmission and hydraulics share the same fluid? NO=engine oil can't get to the manual transmission unless someone did something wrong. YES=same thing. A leaking hydraulic pump will leak fluid into the engine not the other way around unless someone did something wrong. First thing I...

I bit the bullet and ordered this. As it turns out you have to put an 8" sender in a 9" deep tank. I'll consider the extra inch of fuel to be "reserve". Any mechanical option was going to require modification and cutting holes in the hood. This one will require drilling a hole in the dash for...

The tank is steel with a raised filler neck. The tank itself is 9" tall. The sender mounts on a flange with 5 bolts. The bolt pattern apparently fits the the SAE standard flange size, at least as accurately as I can measure. The document about resistances I have says that full is ~75 Ohms and...

Thanks Bob. These are similar to some others I was looking at. When I replaced it last time I made note of the full and empty Ohm readings of the new sender. Now I need to locate my notes. :) If I can find a sender with the correct range of motion readings even at different ohms I can compensate...

The second fuel sender in less then 800 hours has failed. I think the first one lasted 300 hours and the replacement lasted maybe 100. I took the first one apart and in spite of it having redundant contacts on the swing arm/resistor it was worn out to the point it was no longer making reliable...

The replacement pump I got had the inside of the outlet threaded. Just screwed in a pipe plug. If not, a short piece of hose with a bolt that fits and a couple of hose clamps should do it.

I have seen pressure gauges on either side of a valve or tool so you could monitor the pressure drop. Of course that meant that the operator had to be schooled in interpreting (and monitoring) the system. It also meant the operator had to have a better understanding of a system than "green good...

Nice! That and a pressure gauge on the output side of the pump could prove useful in troubleshooting. With that gauge, if it goes into by-pass mode, how do you tell ? I've thought about replacing the pickup screen system with a suction filter setup but have never pursued the "engineering" of it...

The white spin on filter appears to be a suction line filter. Is that a temperature gauge on the filter housing? Where does the pipe on the filter come from and where does it go to? If this is the suction line for the 3PT hydraulics, I would change out that filter first. As for the control...

I didn't find a listing for Farmpro 254. The links I sent for parts show kind of a generic setup that covers most all models. Do you have a screw on filter that is accessible from the outside of the tractor? They used several different hydraulic layouts. For example my Jinma 284 has only one...

See if this parts diagram matches your valve assembly. Distributor Valve - 18-28HP Tractors | Jinma Tractor Parts, Farm Pro Tractor Parts | Circle G Tractor Parts There is no seal shown for the control lever shaft but I find it hard to believe there isn't at least an o-ring in there somewhere...

besides the cavitation issue at the pump gears, there is also the problem of "sucking" thick fluid through the fine mesh pickup screen in the tank. Then there is the long trip from the tank to the pump through a thin walled steel tube that is exposed to the cold. Another radiator... I was a...

My 284 has the same issue. The problem is two fold. One is the great mass of the cast iron that makes up the hydraulic tank and the axle underneath it compared to the relatively small mass of the fluid itself. The hydraulic pump is the only way to insert energy into the fluid so it takes a very...

Hmm, that does not look like the pump in my parts book. I will have to take a look at the one on the tractor to see what matches mine. I was thinking of a steering wheel puller, which is almost exactly like the one Bob mentioned. You may be able to find one that can bolt onto all 4 holes...

From the parts diagram it looks like the pulley just slides onto the shaft. Take the nut off the end and it should come off. It may need some persuasion as in tapping or worst case use a pulley puller or shop press. It should not be on that tight unless badly rusted. Use your favorite...

If you will pardon the pun, I am a bit "stuck" on this one. Having never done this myself, the parts pictures are the only thing I have to go on. Using an O-ring in this application can be a bit fiddly because everything has to be just right to get the proper fit for sealing and yet allow it to...

I use 80W-90 in all the manual gear boxes of the 284. Different weight hydraulic fluid for different seasons, sometimes even ATF in the winter. As for the stuck o-ring, I'm trying to imagine what you are describing. Any chance you can post a picture?

There should be a button on the inside of the rear cover that is supposed to prevent the lift arms from going up too far, thus keeping the piston in the cylinder. Since you have it upside down and apart, you should be able to check that before re-assembly. As for torque, I don't have the info in...

Good thing you got in there to do some TLC. I think your assessment of the dings in the piston are correct. IF the lever was in the down position and the 3pt had lowered itself normally the piston would be at the bottom of the travel. Then if something (or someone) manually picked up the lift...

That linkage arm not being connected probably contributed to your situation. It is good to know that you can access the cylinder by removing the front and rear covers. I wasn't sure it would give enough room to work inside. Here is a picture of my adjusting knob and set-screw. 2006 284

The knob under the seat does not switch between 3 point and aux, it's sole function is to control the speed at which the 3pt lowers. The 3 point lift cylinder is only a one way cylinder in that there is only pressurized fluid on one side of the piston and it takes an external force (weight on...

I doubt that the seal failed at the bottom. This usually happens if the piston extends (raises the arms) too far. The knob on the valve usually has a set or "tension" screw that keeps it in place. If this is too tight then it makes the knob hard to turn. Basically all this valve does is regulate...

With the trans in neutral and the clutch engaged (not pushed in) if you turn the engine over, can you observe the shaft at the point where it goes through the throw out bearing to see if it turns with the engine? It would seem that the splines on the driven disk are the weakest point in the...

Wow! That is a story for the books. I wonder if two engineers were working on the separate assemblies at the same time and both managed to get the same "open number" ? I'll bet worse things have happened! We should get a cold drink sometime and swap "war stories from the parts department". Cheers!

Yeah, it looks like only about half the length of the splines were engaged. More force than they could take at half of the rated contact area.

I was in parts at a CAT dealer for a few years and understand the importance of correct machine ID. It was the same for medium duty GM trucks. If you didn't have the line sheets finding the right part was just a guess. VERY difficult to convince customers that no, "they are not all the same"...

Hi Bob, Have you actually seen them use the same number for different sized parts on different model tractors? That would drive the parts people nuts! I remember doing part number updates from GM way back in the 1980's. We always kept all the old numbers on the shelf for an easy reference. One...

I saw some scanners in the $200 to $500 range the other day that looked like they might do a decent job. Even if not the greatest, they would at least get a file generated that had the basics. After that it is just checking and cleaning up the details. You could get some pretty complicated...

Two main sources for me are Thingiverse and stl finder. Search the interwebs or I can post links if that is allowed.

I got into this in January with an Ender 3 Pro and some basic filament. Less than $300 delivered. I had a few ideas of what could be done and actually had a request from the wife to make a part that has never been made before and can not be bought. The printer worked out of the box and the only...

Where did you get the new one from? That dealer should be working to get the correct part. Even if that is the part provided to them with the correct part number, it obviously is not correct. This is not to blame the dealer, but it is their responsibility to get you the correct part, even if it...

Another consideration is your freeze/thaw cycles. If the concrete is wet and freezes the ice will shatter the cement that binds the aggregate. This causes it to all reduce to the mix that made the concrete in the first place, only smaller. I put crushed asphalt on 400' with a good slope 20 years...

A stuck injector rack is not unheard of. I would suggest draining the IP crankcase oil and refilling with fresh motor oil. The governor and IP are lubed by the same sump and oil changes are often overlooked. Might not fix you problem but certainly won't hurt. Only takes a few ounces of oil...

That would be quite a task, but not impossible if you can get the right parts or be able to make modifications so the parts you do get fit. Jinma has used several different designs of power steering systems over the years. If you don't have a parts manual for your specific tractor, take a look...

Yes. The amp-meter is in the circuit before the switch which controls everything else. It is likely you could have a blown fuse or a broken wire or a bad key switch. Do you have the owners manual or a wiring schematic? I can help you with some basic troubleshooting to see if you can find the...

Yeah Bob, I do. Not in this picture are switches for the Bat-Grapple, Bat-Smokescreen, and Bat-Ejection seat! Criminals Beware. Meanwhile, back at the Bat-cave, the Bat-guano is getting a little deep! Actually, a few years back the stock switches were wearing out and or so dirty they didn't...

(y)

I forgot there were two brackets that mounted on the studs from the back side. My parts manual does not show it but you can see a photo here: 0304-112 Cluster Gauge | Jinma, Farm Pro and Nortrac Tractors | Circle G You can see the outside clips that I made in this photo. I used a clip-nut on...

There are 4 studs mounted to the back side of the instrument cluster. It is a real bugger to wiggle your hands with a wrench up behind the fuel tank to get to the nuts. Getting them off is hard, putting it back together is harder. I made clips that hold mine in from the instrument side. Not as...
