My last Question on the three point lift was answered so well I thought I would try my next problem. The PTO clutch and hub assembly comes forward when tryng to disengage the pto. The driving plates come out of the PTO clutch spider! Question 1, what should prevent this from happening? the self locking set screw (item 60)on page 42 fig 0745B that looks like it goes into the clutch hub? The sliding sleeve will release from the adjusting ring with a quick pry through the acces cover. However the assembly will move forward with the shift lever rather than release the clutch as it should. There are two details on clutch lever, one shows a bracket that prevents the clutch lever from going too far forward. The other shows a push rod that looks like it should lock the lever in place (mine has the push rod)however I do not see what this locks to,to prevent excess travel of the clutch lever. I should add that the seals leak and transmission fluid is on the clutch plates. Sorry for the long description but I thought all the info would be helpful. This website is great and a tremendous asset. Thanks in advance!

From your description you have a pin out in the shaft which goes through the trans. This lets clutch slip ahead and the plates fall out. I don't remember whether you can pull it out of the back without taking anything apart in the clutch or not

Sounds like you are using an I&T shop manual from your illustration discription. I haven't gotten into my pto clutch on my Super 55, but it looks like that set screw, item 60, should keep the clutch assembly from moving. As far as a stop for your PTO lever, I don't have the newer lever on mine, but I believe the way the newer lever works it you push down to drop that catch below the stop bolt and slowly and steadily pull the lever back. That stop bolt is intended to keep you from accidently engaging the PTO. The snap into position happens when the clutch is properly adjusted. Are you working through the hand hole cover or do you have your tractor split? Sorry I can't be of more help. Hopefully someone who has gone into the PTO clutch will reply. Good luck.

I have the clutch back in the spider through the hand hole. The tractor is not split. I tightened the set screw and that does prevent it from sliding forward. The pto does not shut off completely now when the clutch unlocks. I think there is too much oil on the clutch and friction plates. I may have to do a split this winter and fix the seals. Any other ideas are appreiciated. Thanks for the help. Dan.

Yeah, I was going to mention that you should replace those seals. When you get ready to do that I have the manual and can copy it for you. The PTO shaft will spin a bit when it is disengaged, but if you put a load on it in that position it should stop. The mechanic at the tractor shop grabed mine in the disengaged position, but I wouldn't suggest it.

There are two set screws that hold your clutch in place..one on top of the other, to act as a lock. I could never keep them tight and in place; therefore, I replaced the screws with a longer set screw that I drilled and wired so it wouldn't back out and loosen. If it seems confusing, I will forward details. Incidently, my seals leak and the clutch is drenched, and with proper adjustment, I have had no slippage. Good Luck!
