Duane Kaufman,
I agree that your throwout bearing may have disintegrated. It could also be the pressure plate collapsed, or lost fingers.

Right now I have a 335 here that the pressure plate collapsed and soon I will be splitting the tractor. Normally I always install a rebuilt pressure plate, throwout bearing, and grease hose when I do a clutch job. Mower tractors normally eat the pressure plate due to the foot riding the clutch.

Happy wrenching.

 Re: MM 445 clutch problems in reply to Charlie Bilerx, 07-08-2013 17:23:35  
Hello all,
I have verified that the problem I am having is _not_ due to travel or clutch adjustment, so it looks like I'll be splitting the tractor.
This tractor doesn't see much use (less than 100 hours/year) The Ampli-Torc needs to be _completely_ warmed up so it does not slip in low-range.
Now comes a more philosophical question(s):
1) With the tractor split, should I go and re-build the Ampli-Torc? (This tractor has a loader mounted on it)
2) How much more effort (beyond what needs to be done to fix my clutch problem) is re-building the Ampli-Torc?
3) Are Ampli-Torc parts available? From where?

Appreciate your hard-fought wisdom on this matter.
