Split the 340 U: Question re: the TA clutch

Moondoggie · Mar 7, 2010

I split the 340U over the last 2 weekends to repair the TA clutch which was non functional. The TA assembly looks good. The pressure plate looks good as well as the back plate and the disk. But I can't get the 19/32" dimension between the the back of the back plate and the bottom of the pressure plate suggested in the IT manual. Seems either the fingers are worn or the surface of the back plate is worn by at least 3/16". At that dimension, the plate would be worn through. Should I just replace the plates and the disc and be done with it? Or am I missing something?

The specification is given for overhauling the pressure plate assembly. That is the dimension used to set the lever height. There should be another spec given for lever height.

When using a clutch stand, the levers are pushed down to the specification given and then they are adjusted until you have 19/32" between the backing plate and the test stand.

When assembling the TA clutch in the tractor you do not need to worry about that spec. As long as there is not excessive wear in any of the parts and when assembled the levers are about parallel with the flywheel you should be good to go.
