Traction LK3054 FWD Slipping under load

kentrodngun · Nov 6, 2017

Hi all. My tractor has been working fine but the front end has been leaking for years. I finally got the time to do the job and replaced the front seals. When I put it all back together, the FWD seemed fine but under a load, it slips. I drained the 90 weight and pulled both sides again. Drive gears are perfect - no chipped or missing teeth. Could I have assembled it wrong? It seemed pretty straight forward. Could it be the "wheel bearing type" bearing on top of the shaft which drives the gears?

Sounds like this is a dealer question but I figured I'd throw it out there in case someone had and solved a similar issue. On the lift, the front wheels move, it is just under a load (FEL full or going up a steep incline) that the left side engages, slips and re-engages. Thoughts or suggestions? Thanks.

By "slips" do you mean gears jumping cogs? As in a ratcheting sound?

If so, it's certainly an assembly problem.

Well, actually, if it was working fine before, just leaking, and now "slips" it's definitely an assembly problem.

Hopefully an experienced owner/mechanic can chime in with the most likely cause.

Bummer, sorry for your hassles.

Are you sure its not just the front differential working as it should? There is no differential lock on the front axle so if a tire loses traction it will spin and not produce any thrust on the other side.

Ovrszd, I agree, hopefully a dealer will chime in and tell me what I did wrong.

jabelding, I've owned this tractor since 2003 and have never had this problem before. I usually have it in FWD due to my property inclines. Under a load, it slips and I lose traction, the left wheel stops completely and then re-engages. Something is certainly wrong and with winter coming I need to plow and not ruin the gears or worse.

Sounds like you may have a bad spline on one of the shafts probably the one from the differential out to the wheel. they will slip and re engage if they are moving around (in and out)

Does Kioti have an online parts source?? A place where we could see a parts diagram of the front drive assembly??

It appears they do. Take a look at this website for parts diagrams that apply to your tractor. When you are looking at the right one maybe link us to it. More sets of eyes looking at it might find what you missed.

If the shafts that slip into the center drive section and run out to the front hub assemblies are held in place by a snap ring or some other method, maybe you didn't get one together right and it's sliding apart as mentioned by jabelding??

Not sure your 4wd works the same as my DK45. I am stuck in 4wd all the time. If I turn on 4wd switch it keep slipping out under load. The Dk45 pushes the front drive shaft hydraulically in a dog clutch to engage 4wd. A spring disengages the shaft when hydraulic pressure is released. Put her up against a solid object with 4wd switch off and see if front wheel spins. I do not know why mine will slip with 4wd switch on. Was going to split tractor myself but decided to let dealer deal with it when I can spare it.
