New Jinma 254 - Help please!

[JINMA224XR]

<font color="blue"> Most of the plugs you mentioned are fitted with shake-proof steel washers, not copper or rubber, so I assumed they were mounting bolts

Another one for you: There is a gas spring fitted to hold the hood open. Problem is it won't close - if I press hard, the fibreglass just bends - and I guess it is too strong for the light body. For now, just using it as a prop.

Hey ACM,

On my 224, the front drive drain plugs are very small, about 7mm square headed threaded plugs, and located on the lower left and right steering struts, and on the right side of the center, looking at tractor from the rear.

I think Bill has a very good idea about isolating the Glow Plug circuit. I also did that, before I figured out that they had a 10amp, where a 30amp fuse should be. On my y380t engine- there is a thin flat metal bar that connects the glow plugs. There is also an insulating washer on each glow plug, that prevents, shorting the circuit to the chassis. One of the very small insulating washers may be missing or all 3 may be missing, which would short the circuit and blow the fuse.

Also Greg, may have it pegged as a bad ignition switch. But I would check out the connections at the glow plugs to make sure that all is well there first.

You asked if you might have the ignition switch wired wrong, That is also a possibility, but Someone else will have to help you with that one.

Oh by the way, I got mine allready assembled, and there was a couple of wires under the hood that wasn't hooked up to anything. I don't know exactly what they are for, but it might have something to do with the upgrade to the new headlight circuit, that eliminates the low beam, but just a guess, or it might be to the horn on the steering wheel, which is not connected on my 224, still just a guess.

Be sure to check that your creeper gears are getting oil, if you have a creeper gear box.

The drain plugs on the transfer/4wd gear box, have flat sealing washer as well as the Transmission drain plugs in line with the rear axle, on my 224, I have 2 drain plugs for the transmission on each side of center, at the rear axle.

There may be an adjustment screw for your Spring Strut on the hood. If not I would take the strut off and try to make sure that the plunger is going all the way in. If the plunger is going all the way in, then you may have to relocate a bracket maybe, or just leave it off and rig up a straight rod support, as my Nissan Truck has, to keep the hood propped up.

I hope that you get good use out of your tractor, as I don't know how I would make it without mine. As my current situation, is just me and my tractor to get the job done. Mine has been a lifesaver for me. I know that mine is just a little 224, but it has been doing quiet a bit of work for me.

Did you get the Spring Seat with your Tractor?

Hi Dick, Joe, Greg & Bill,

Thank you, gentlemen, for all you kind help.

Re. the 30A fuse, I'm afraid it is what I always hate most - the intermittent fault /forums/images/graemlins/mad.gif Since my last post I must have heated the plugs and started up 10 times with no problems at all! Guess it will wait until cold weather comes before playing up again ....

Got the gas ram working after a few gentle passes through the hydraulic press. Also hood bracket was slightly out of alignment. Still stiff, but now closes.

Re. your questions: no spring seat, no shuttle box. Does have creeper but have not yet been able to shift it out of H (as supplied). Seems very stiff - may have to take the top off and check. Other gears, PTO, 4WD, diff lock seem to work OK.

Hydraulics a bit sluggish compared to my old Kubota KH36 minidigger, perhaps because only AWE 46 available locally - will search for 32 tomorrow. I plan another full fluids change after a few hours running in, so it is no extra trouble.

I too have some 'spare' wires - orange, white and red/white (not numbered). Perhaps steering wheel horn push? Don't think they have anything to do with the lack of dipped headlights - I find that both the outer and inner pairs of front lights are wired to the single position 'main beam' switch, so I guess dipped is no longer available. May have to make some alterations.

Any ideas on 'generic' paint shades (red, grey) to touch up the minor shipping damage?

Many thanks to you all.
ACM

Hey ACM,

That's a good excuse to take the cover off to make sure that you have oil in the creeper gear box. Mine didn't have very much at all, but I didn't know enough, to check it, until I had many hours of hard use. It never dawned on me that the creeper gear box wasn't getting oil, but I didn't have any trouble shifting from High to Low position.

I would caution against trying to put too much pressure on the Gear Changer for the Creeper Gears, as it might bend the Shifter Paul. I very rarely use the Low side of the Creeper Gear Box, but I can see that it would come in handy for certain kinds if jobs that need a really low tractor motion speed.

I would try to get another gasket before removing top, but if you are very very careful, you might be able to remove the top and reuse the old gasket, or at least until you get a new one. I don't like to use gasket maker, Especially the tube type/form a gasket, but that is also an option. The best alternative that I have heard of is using old inner tube to make a reusable gasket. That idea came from JohnS. He has a website that you might find really useful, for troubleshooting a Jinma tractor and has many useful Maintenance procedures with really nice pictures.

If you get the chance to upgrade to the OEM Spring Seat, at a good price, I think that you might like it. The OEM Spring Seat is a good quality seat and the adjustment for body weight helps to really smooth out the jolts. I knew that I wanted one, when I ordered my tractor, but was a little bit worried if it would help very much. After 125 hours on my 224, I would not want to get on another tractor without a Spring Seat now.

One of the things that I would like to put on my tractor is some rear view mirrors, so that i don't have to be twisting around to see exactly where I am going all of the time.

An intermitent problem with the 30a fuse, might be a little bit troublesome to track down. I'm leaning a little bit toward the ignition switch now. I have heard that some of the ignition switches were still supplying current to the Glow Plugs after the Starter is engaged, and that might be blowing the 30a fuse. Still just another guess.

There is also another Tractor Forum Site that you might find interesting to browse Through, "NYTO Forum" Site.

All these sites have a wealth of troubleshooting ideas and are interesting to read about how to keep your tractor Healthy.

Have to concur with all that was said above. The mysterious fuse blowing at times but now okay bugs me. Could be a bad ignition switch, a wire on the affected circuit was touching ground and you inadvertatly moved it, a bad glow plug that finally went open circuit, too many possibilities.
Creeper hard to shift may a bind in lever. Don't force, pull cover and take a look see. Gears are square cut teeth so stiff shift is expected (shift from a stop only please). Creeper cover comes off easy and gasket usually comes off intact. I resused mine. If not use a gasket in a tube with moderation.
Drains, trans/creeper/transfer case have 4 drains.
front diff 3
hydraulics 1.

Since most of the other questions have been answered, I will try the hood shock.I have seen several crate tractors that the assembiler did not install the L- shaped angle iron brackets that support the hood and that the pressure from the hood shock has cracked the fiberglass,did you install these 2- brackets they have 3-slots in one end that the hood hinge bolts go thru ???????and the other side bolts to a rectanglar angle iron frame that the hood shock is on.

Hi Joe,

Thanks again for your kind help and information.

I've checked out the sites you suggested - very useful.

Hoping to get time to take the creeper cover off today, so will see what is what. (And check that it still starts /forums/images/graemlins/smile.gif).

I'm from south coast UK (New Forest, near Southampton) but recently relocated to France, about 1 hour drive SW of Toulouse. More space, cheaper land, less urbanisation, better climate .... but fewer tractor parts!

have a good day!
ACM

Thanks Harry.

I now suspect the ignition switch. Have Ford ready as spare.
Hope to check creeper today.
best regards
ACM

Hi Tommy,

Many thanks for hitting this problem.
Angle brackets? What angle brackets? None such in my pack /forums/images/graemlins/confused.gif
Telephoned the UK dealer - he is shipping them today. So I guess you got it in one!
have a good day

My fuse does that sometimes when I preheat. I think I have noticed that the headlamps are on at those times. I bump the swithes with my knee easily. I haven't confirmed that the lights and preheat at the same time is the culprit as I have only done it twice.

Hi All,

Checked creeper - plenty of oil but H/L select needed freeing up - guess it got stiff thru lack of use since assembly.

So, all is now working /forums/images/graemlins/smile.gif. Thanks to all you kind gentlemen, a fairly simple and enjoyable assembly. Should also mention that Jinma UK were at the phone today (yesterday was holiday in UK) and seemed both knowledgeable and helpful. Hope they (and you guys!) stick with me if there are problems during run-in.

Again, many thanks to you all. Hope I get a chance to reciprocate.
