Clutch slipping after warmup

[Duramax88]

Hi I have a Jinma 354 4x4 and just had the engine replaced. Now when I start up my tractor to use it the clutch works fine then about 20 minuetes later the clutch slips to the point that the tractor will not move. Not sure what the problem is but any help would be appreciated. Thank You.

The clutch is inside the bell housing, and it's likely whoever replaced the engine split the tractor at that point to replace the engine. My guess is that the clutch release linkage rod was improperly adjusted when the two halves of the tractor were put back together. That's the external rod that connects your clutch pedal to the clutch release arm sticking out the side of the bell housing. During that 20 minutes leading up to the clutch not holding, do you detect a burning smell?

No smell just starts to slip and tractor will not move after about 20 minuetes. Thanks

Ok. Need more info to narrow down the problem then. Open the clutch inspection window and get a visual. All clutch release finger tips should be just that - tips. They should not be worn or wearing flat. Is the gap between the finger tips and the face of the throwout bearing correct? There should be a visible gap, but it should be no more than 1/8" or 3mm. Does the throw out bearing case look bluish? When it stops moving after 20 minutes, is it in a high gear or range? If yes, will the tractor move again if you shift the transmission to a lower gear and/or select Low range?

Hi I will get back to you as soon as I get the side plates open. It looks like I have to remove part of the front loader to get to the side plates. Thanks
