Hi, I need some advise. Own a mid 60's HD-21 with a clutch or torque converter problem. Any mechanics out there familiar with these machines?
The old girl has a wet clutch, torque converter, and power shift trans. Power is slow and weak making it through to the drive shaft. After first starting the engine the crawler will not move (after shifting) but as it warms up will begin to respond but even then does not seem to push like it should.
I have changed to atf and filter, cleaned the screen at the bottom of the torque converter and cussed the hell out of it....no luck. Any ideas?
