I'm around. My tractor with SUDT2 will be done this summer, I expect my fathers with the 424 to follow not long after.

The dk45se had backhoe overheating issues in some heavy use instances, Kioti issued a fix for this, which involved repurposing the transmission case fill/vent, as the new remote circuit fluid return port, which allowed for less restriction in fluid return than the built in remote return. It...

Back in 2018, when I had the analysis of this thread done, I refilled with Travelers again. When the next change came along in 2022 the next analysis was on par for the hours compared to the previous analysis, the copper level had not decreased, which is notable. So by this point, I had run...

I try not to be a parts thrower, but I know the DK SE series was plagued with starter relay troubles, including mine. A quick $15 try, as the relay is standard type. See pic below for location

TN8Man, I made a comparison write up of this filter a few years back, here is the link Kioti HST filter vs Donaldson HST filter, Opened both.

I drilled two holes in the fender a few years ago when I needed to replace a cable. worked great. I touched up the rough edges of the holes, treated them for rust, and left them open. Worked out great and for my uses I have had no need to cover them. Hardest part was making sure I lined up...

Here's a thread from 2017 of a similar tractor and story. May be useful for some folks to have this in one place. https://www.tractorbynet.com/forums/threads/dk40-front-bearing-failure-1300-hours.375598/ Not common, but common enough. If it ever happens to one of mine, (just over 800hrs now)...

Both DKSE tractors I've operated never really go above the second dot unless something is wrong. That DK40se should have removable screens in front of the radiator to keep most of the mess out of the radiator fins. The radiator itself may look good, but if the screens are clogged, the air flow...

I've had mine out. Had a pinched cable that was stiff, to replace. DK45se, Wound up drilling two holes underneath the fender, aligned with the bolts. Aggressive? maybe, but it was sure easy after that.

Welcome to the forum mwhitehill. Front pivots are often set up as per the drawing below. The grease fills up the small space between the axle pivot pin and the housing in which the pin pivots inside of. There is also a seal that keeps the grease in and dust out of the pivot. That seal is...

I'm feeling some play on the water pump when checking my belt during an oil change. Mechanical seal not leaking yet. Anyone else have a premature water pump failure?

I've used my 4501 pretty extensively over the last 2-3 years since this post. I would definitely buy it again. It's a very straightforward winch. Rugged and easy to operate. I remember having concerns about sizing of the 4501 on the dk45se. Its a great fit. I have never wished it were smaller...

The below picture and description from the LK30 manual may assist you, if this is the tractor in question. these fuel valves are often very similar across models as well.

Information from a kioti manual in regards to gearing and the front axle.

Could be your neutral valves hanging up. Take each of them out to clean/inspect. Have a look at this clip which explains their operation. For location of these two valves, see Item 36 of this diagram.

You can see here in this diagram of the front axle, that once the front axle fwd and aft pivot point bearing housings are full, there is no where for the grease to go. For the front pivot, slowly over time, the grease will leak passed the seal, to the exterior of the housing. If you wish to...

Here's a scan of the maintenance schedule chart from the CK2610 owners manual:

While most all axial piston pumps are similar, the actuation of the swashplate varies a lot, especially when it comes to tractors, some are direct linkages others use pilot systems, and again still there is electronic actuation. From what I am seeing here, it looks like your CK30 has a few...

Conclusion: I've arrived home, checked the jumper myself. less than 1/16th out from pin hole to pin hole. The mit indicated 0.040, MUCH better. Mounted up to the cutter and she's as smooth as a new cutter should be. So I can confidently say that a stump jumper like this will certainly cause...

Toolbox dump. Mine: *Specific 2 wrenches for cutter slip clutch and blower shear pins. *utility knife *Extra pins *Zip ties *Electrical tape *Wire jumper *Needle nose Pliers *Lutz 6 in 1 screwdriver *No name Adj wrench with Hammer top *8"Bahco wide jaw Adj Wrench *10" Knipex Pliers wrench...

I had numerous issues on both my Dkse tractors upon delivery as well. Most all problems were dealer assembly issues. Between the two tractors, *Crushed hyd steering hoses when loader was installed *Steering knuckle bolts were loose *loose loader bolts *lockwashers on wrong end of fastener...

Replacement stump jumper arrived a few days ago. During my absence, my lovely assistant has taken measurement of this one. It appears much better. When I get back, I'll go over it, and mount it up. I think its safe to assume all unusual vibrations will be sorted at this point. In the mean...

Yes they can. Have a look at this screenshot here, a different view than before. Just take the 4 screws out and have a look at the baffle plate, #5. It could be gummed up stuck against the seal. A quick thing to rule out while troubleshooting, and with some luck, it could solve your problem.

Here's a snip from the Kioti manual for the DKse tractors. Really isn't much going on there, but #11, the oil baffle plate, would be easy to have a look at. If OP can rule that out, its one more thing off the troubleshoot check list.

Ill be removing the stump jumper again here in a few days, but from my photo stock pile, you can see here, that the blade bar is a riser type. The spindle collar appears to be mounted flat to the bar, and the bars both ends appear to be welded flat to the pan, but I think the riser bends in the...

I wanted to see what folks thought about this new stump jumper. Seems too far out of wack to me. As the photos show, run out difference is about 1/4". When mounted to the mower, one blade hangs exactly at the bottom of the cutter walls, and the other is about 1.5" higher. I have a video of...

Best bet is often leaving the barrel side mounted to the loader, getting the proper spanner or rod in the hole, and hammering on the spanner or rod to spin the gland free. This way, the tractor is holding the barrel for you. If the cylinder is already removed from the tractor, be careful with...

Dadannyboy, I can offer up this page. This is the same system the newer dk35, 40, 45, 50se tractors use. I would imagine its very similar to what you have in the older dk tracor. This should definitely get you in the ballpark on flow rates and pressures.

Most common quick coupler sizes you'll find around the farm are here

This is a pretty accurate assessment here. Why pay so much more for something you don't need? Simply because the company who benefits most from the sale says its best for you? I'm certainly not saying go buy a pail of Super S, THF 303, or starfire tractor hydraulic transmission fluid, but I...

Ive used traveller universal prem for a while now. Here is the last oil sample analysis on it. Because it is a cheaper oil, I think it is important to watch it. So far, I am getting good results. Here is the longer thread discussion from the past on this...

Justman777 is exactly correct here and may be pointing to the problem. Hydraulic fluid return should not be terminating above fluid level in a reservoir. So this spraying noise in the reservoir that has been noted is suspicious, and could be a tel tail. have a read of chapter 6 here CHAPTER...

Hello all, Could anyone guide me to the location of the AC blower motor resistor in a TN75DA? Only one speed works, and I'm suspicious of the blower motor resistor. The 3 speed switch in the cab ceiling is good. AC works fine, blows cold. I just only have one speed.

Have a look here, this is your gear ID on the front of the engine. It may be possible to ID which gear it came from by gauging the tooth length, if you have a tooth piece that is complete, and compare that length to the thickness of each gear (should the dealer have the spare parts to measure...

Myself, I'd be worried about forgetting, in the moment, those toolboxes are not fixed and lift something to the maximum height, and they both fall off. Or letting someone else use the tractor, and them not realizing, and doing the same. Would they fall off, or slide down at full lift? Still...

See this attachment for a kioti product support bulletin from 2014, Most everyone's oil requirements from Kioti are on here. note the bottom where it says SAE 80W-90 gear oil or transmission fluid.

While I'm unsure of your CK3510hse, maybe this information can correlate is some helpful way. My DK45se hst lower radiator hose is 34mm ID, and 44mm OD Kats 1.5" heater (16600) is 34mm ID and 38mm OD with a 40mm bump out lip and the edge. This worked out to be a great fit. Stuffing the 40mm...

Yes, its called a Tandem pump, as you can see in your drawing, pump #1 services your loader valve, then your 3pt hitch, pump #2 services your modulator valve for the pto, 4wd clutch, power steering, and then onto your Hst. If this is your tractors drawing, I can see that the particular...

I suppose the most interesting thing to me is that both of the hydraulic pumps have failed. I suppose that points to particular causes of the failure. Other than the hydraulic pumps being bad, the only other possibility on my mind would be return fluid from the joystick valve or power steering...

WGbowes, what Eric is saying here is the spot on. Not a complicated or expensive problem to fix at all. here's your wire diagram to go along with Eric's diagnosis. Welcome to the forum!

At my dk45se 50 hr service, I used Traveller Premium Universal Tractor Trans/Hydraulic Fluid. Lots of opinions on oils out there, so I thought I could add to the conversation my oil sample analysis from my 400hr service. Oil filters used during this time: * Kioti T5710-38031 hydraulic oil...

I'll start by saying this surely isn't necessary, but I enjoy the tinkering. I stumbled over this hydraulic filter magnet while looking through a manual for the DKse tractor's twin from Australia, the EX. In the exploded parts view of the filter housing there was part #T4260-38841 "magnet...

So, the Kioti T4125-38021 HST filter, the higher pressure, thick shell, $100 one from the dealer was the only option. No cross references. But, in the past couple years a few options started popping up. A while back I noted in the cross reference thread of installing a $40 Donaldson 573481...

I really like the Messick videos, but after seeing this one about napa/wix oil filter Napa Filters VS Kubota Filters - Do you need OEM filters? - YouTube I wanted to set the record straight a bit. They have a pretty unusual napa gold/wix filter there with a small filter cartridge inside. This...

Have a look at this document. specifically the "front axle oil" column, near the bottom. Then have a look over at the "potential transmission oil supplier and name" block. If there is question of whether its good enough for the small front axle, ask yourself, what lubricates the rear axle?

The zerk thread size is 1/8 28 BSPT I had spent a lot of time figuring it out in the past, and where to find them, as the dealer didnt always have them. and when they did, only had a few laying around. Frustrating. You can find them online here: 1/8-28 BSP Straight British Grease Zerk Nipple...

Other than the parts manual as you stated, I have this. The spool, Item 54 here, is what moves back and fourth inside the power piston assembly to actuate the axial piston pump swash plate. If the HST must come out to access this valve, the tractor must be split and hst removed. But before...

To help determin your linkage adjustment was correct, have a look at this picture. Its from a Kioti EX machine, an Australian version of the DKse series. I have found it to be very accurate on mine. So I have no reason to believe these measurements would be different than yours, but use some...

Bad luck. I wonder if the linkage was out of adjustment causing something to bind? It appears as though you only need Item 81 in this here drawing. Also see item #81 part# here. Parts Finder Michigan Iron & Equipment Morrice, MI (855) 265-459 You may need to strip some framework off to get...

Best I can find is this. But has no part numbers. Kiotis own workshop manual says to replace the steering unit if there is internal leakage. Having said that, 20 minutes does not seem long enough to heatsoak the system to the point of steering unit failure, especially with an HST tractor...

Something fairly easy to check. Have a look at this page from the manual for setting the position lever range.

I think the donaldson hst filter is a P573481, you're just missing the 1 at the end there. My Workshop manual for the EX45C (almost exact to the DKse series) says more clearly than our US owners manuals to change the hydro and HST filters at 200hrs. The NX may require different, but I...

I've installed a lower radiator hose heater in one of my DK45se tractors. Radiator hose size: 44mm OD, 34mm ID Kats 16600, a 600Watt 1.5" in line heater, Slighly larger than what is needed, but its the best fit, and fits fine. ($37) Plugged in over night, from about 8pm to 8am. Ambient temp...

He's talking about folding the seal up like this: either with a tool or your hands, to help install the seal. They can be quite difficult to install if you have not done one before and have not been shown. He also mentions to warm the seals up in hot water to make them more pliable, which...

I think what he is talking about here is the spiral bevel gear, and the bevel pinion gear (ring and pinion) of the front axle,which have teeth that are far more robust when working in the fwd direction than in reverse due to the profile of the teeth. I've seen this exact scenario play out...

atcNick, It seems you are very new to mechanical equipment like this. Glad you are asking questions. Lots of people here that are glad to help. Take a look at this page, It goes over your CK30 hydraulic oil and filter change. Here also, for future reference as you get into your tractor...

This may assist in visualizing a 3rd function as well.

It would be interesting to know what oil they used at the dealer you purchased the tractor from. I've run into a dealer that was using an oil not even on the kioti list (see below), but because it was cheap they went for it. * So it may be a possibility that the oil in your transmission is...

The Sub-change speed sensor is the range shift sensor for the HST tractors, pin 12 and 8 of the cruise unit. But I'm not talking about changing any of the pin arrangements or splicing any of the interlock wires, none of which should mind if you are going in reverse, so long as the...

Great Question, I had the same one. I ran with a few ideas based off things I've seen. The photos below show you where I've built in a chainsaw holdster and a tool box for things like Files, Wedges, Extra saw chains, ect. Both the Holdster and Ammo/Toolbox are quickly removable and lift...

Follow Up. So I wound up purchasing an Igland 4501 from Reed Supply Co. in Vermont. $3000 shipped. Came with PTO shaft, 3 chokers, 3 slides and 165ft of cable on the drum. Availability at the time was a large factor, as they had them ready to ship. I really liked the Fransgard V-4000 winch...

So I have a Kioti DK45se HST, I'd like to get a logging winch for firewood, as well as wood for timber framing, which can often be timber of 2 1/2ft in diameter. which winch would you recommend putting behind this tractor, the Igland 3501 or 4501? I'm one for leaning a bit on the larger side...

Were you greasing that zerk on the upper shaft support? (blue arrow in drawing) Thats the only way that upper bearing gets properly lubricated. If you were, perhaps the shims (where the green arrow is pointing) were not correct from factory, causing too much play. I'm curious what you find...

Maybe someone with an LK will chime in, but I'll say if its part # T4240-14212 it appears to just be a rubber push in with a sight glass face. The parts diagram I'm looking at over at Nolts Power Equipment, as well as MIE show its either part# T4680-14211 or T4240-14212 that second part number...

Have a look at this picture. Its a great profile view of the 4 most common hydro quick connects that we would use, and their designations and compatibility. The first one in the picture, the HT series flush face, is nice, as its easier to keep the faces clean and keep debris out of your...

I've got the manual for the EX35, 40, 45, and 50, which is very similar to the DKse series, I believe its the same tractor but for the Aussie market. There are a few differences, but minor. I have yet to get the proper DKse manual in PDF that I personally require either. The links for...

Actually, looking at a wiring diagram i have here, it may be from your left hand turn signal (2 wires) and tail lamp, (harness) Keep in mind this little diagram is from an EX tractor, similar to a DKse, but in Australia. Just happens to be what I have.

Bypass the start terminals will tell you if the switch is bad or not. Good work so far with troubleshooting. What about the preheat control, that could cause you starting issues. Perhaps this will help, its a screenshot of the wire diagram from a CK 25, 30. I'm not sure what the differences...

So I ordered that magnet Assembly part #T4260-38841 from Messicks. Came to $35.32 after shipping. Not only is this for the EX tractors which are very similar to the DKse series, but also the Cub cadet tractors 8354, 8404, and 8454, which look to be the same platform as the old DK tractors...

I wouldn't sweat the 1" too much. Especially considering the bow out of the tire sidewall itself, compared to the actual tread contact with the ground. The tractor width with Ags may be 55", but the tread contact to the ground may be 53" see this photo to clarify my words. in any case...

It would seem you are exactly correct

Good question. I have a DKse as well. From what I gather in this diagram, that grease zerk services the void between the upper bearing and upper seal. It keeps the upper bearing lubricated, as that bearing sits above the oil level in the axle. This grease also helps keep the seal from drying...

For my DK45SEH maintenance log, I put together this excel sheet. Lots of time spent looking for all the filter cross references, but I like having the options. Perhaps you could find it useful for your DK40SEH

I work in the oil field as well, I'm offshore right now actually. We just went through a 24,000 hour overhaul on one of our 8 wartsila W26 V16 engines. Heres a photo of all the A bank pistons set aside. Well, as a fellow oilfield worker, I need to send you a PM, I've got something you may...

I just like the idea of a magnet that is inside the filter, where you can see if anything serious has gathered every time I change the filter. That "Magnet Assembly" Part# T4260-38841 I was talking about, that can be found in the EX series tractors but not the DK for some reason, can be seen as...

Within the parts manual of the EX50, which is very similar to my DK45SEH, I found a "Magnet Assembly" Part# T4260-38841 which screws into Filter Bracket Part# T4620-38041 for the hydraulic system of the EX series. Looking into my own parts manual for the DK, I found no Magnet Assembly. It is...

I've put an arrow where the thrust bearings are suppose to ride. I cannot confirm this for sure, but it seems very likely. If this is the case, it would explain how they could have just fallen out. Is their any indication that one of the bearing halves that fell out used to have a tab?

Some diesels you can see part of the thrust bearing halves without disassembly, Shot it the dark I suppose, I was curious if this was the case. Is it possible the pieces are from the cover you removed? one can hope. have a look at this. It is your crankshaft and bearings. What manual are you...

So thats where you found the two pieces? they fell out just after you removed the bearing case cover which holds the lip seal? .125 very well may be the thickness of the trust bearing that has fallen out. Could I bother you to take one more photo looking at the area I'm pointing the arrow in...

Well, for my DK45SEH, I have the WR long 3rd function kit from Everything Attachments, which may (or may not) be the same as what you've got. I can't take a good photo of it now, but here it is, zoomed in from an existing picture I have. Maybe it will be of some help until i can get a better...

Looks like you are after Item 13? Its part #T5855-65351 I cant seem to find a size indication though. Item 12 is the Chain Assembly, part # TC26-0015A TC26-15A KIOTI TRACTOR CHECK CHAIN ASSY. | eBay Perhaps someone has a CK4010 right handy and they can take a measure and let you know...

Sure, You can see here in this photo, they simply bolt to the grapple. There are holes in the lower 2 tongs of the grapple itself, the teeth have corresponding holes that are also recessed to get the bolthead out of harms way. There are locknuts underneath.

I think what the photo isn't showing very well are the red teeth extensions that are underneath the bottom hackmatack tree. The have also been drying out for 2 years.

Heres a cutaway drawing of a grease zerk ball check.

My email to them: "Hello, I'm looking for a Workshop Manual in PDF format for a 2014 DK45SEH do you offer this? many thanks" Response: "Good mornning, KIOTI Tractor does not have Workshop Manuals in PDF Format. Since these manuals are Copyright Protected, we do not have "copies" of the...

Oops :ashamed: the inner air filter is supposed to be Wix 46490 (as a note, this inner filter did not come with either of my 2 DK45SEH's) Updated

I have to fold my ROPs down on occasion too, so this is what I came up with. Those brackets don't wobble/vibrate or anything either, been like that for 3 years now and no troubles. They are bright too

Igland Sundown GR 40 Grapple, same as a Frostbite, just not as expensive.

Also, Here is a Spreadsheet I have made of all my cross-referenced filters for my 2014 DK45SEH. I also have volumes, Types, and my own change history on there. Maybe others could find the format useful. I'm not sure if I can put the excel document on here, but this is a screenshot.

Here are a couple exploded views of the axle that may help everyone talk about it.
