My Series ll D17's clutch occasionally slips a lttle under a heavy pull in 3rd gear. For you experts, how can I easily tell if it is the power director clutch or the engine/transmission clutch that is the problem?!

Thanks for your input!

Are you using the low side of 3rd? If so, try the high side of 2nd under the same load. That may tell you if the PD is slipping in the low range. The "feel" of the PD when it snaps into either high or low is also a good indicator. Another thing is to try a PTO load, such as a grinder, to see if the main clutch is slipping by lugging it down. (better yet if a dynamometer is available). Of course, dont do this for very long. Other factors: how long main clutch has been in tractor; service of PD (if any); frequency of those heavy loads; & hours on tractor.

Yes, I have experienced the slipping in low 3rd and hi second occasionally. If all things are equal is it more likely that the engine clutch disc will wear before the P/D clutch? I noticed a year ago that the disc was showing some wear down close to the rivets but I figured it would be ok unless I tried to pull stumps or something similar. I guess I should have changed it to be on the safe side.

Thanks for your reply!!

Donald, I wouuld say all things being equal in low or high range, it would point to main clutch. And if the linings are wore near the rivets, it's gettin down there....probly time for replacement . Another thing that can be an indicator; if the main clutch is slipping under load, you can usually smell it !! whereas the PD wont. (It just gets the hydraulic oil hot...)

Thanks a lot! I guess it's time to split the old girl for replacement. The information you gave is appreciated and the fact that it slips in either hi or low is a reasonable assumption that it is the main clutch. I wished I would have thought of it!!. This site is great for learning/teaching one another.
