Hi-
Got a kit car with a corvair trans (yeah I know- doesn't inspire
much confidence) . Worked well for 2 years. I never beat on it. One day
toward the end of last season, I took it out and suddenly couldn't shift
without an awful grinding sound. The time before that, it was
working perfectly. I decided to replace the clutch (as I thought It
wasn't releasing). When I began to disassemble it, I noticed that the
jam nuts holding the adjustment on the fork pushrod had loosened and the
rod had gotten longer (instead of shorter which would have been my
guess) so I had been driving around with the clutch partially depressed.
I readjusted the rod but apparently the damage had been done and the
grinding continued. You could start the car, shift into first (or for
that matter-2nd, 3rd, or even 4th if you were willing to let it chatter)
and take off from a standing start with no problem. But once the car was
moving- just dare try to pull a shift in either direction...
When it came apart, the trans lube didn't smell burnt and nothing
looked bad- no signs of heat on either the flywheel or the pressure
plate. In fact the flywheel still looked new and the clutch disc was
slightly worn but probably had a lot of miles left in it, however, it
didn't slide back and forth easily on the splines and the thing was
apart so I replaced the diaphragm pressure plate with a borg & beck unit
and installed a new throw out bearing and disc. The next day, it was
back together and I started the car and went flying up the road only to
have the gears grind at least as loud as before. The clutch seems to be
releasing fine, at least it tests that way. Did I fried the syncros
when the rod adjustment went bogus? I have some new ones but don't
relish the thought of pressing everything off the main shaft.
The fork looks ok but who knows? Any ideas? Is there a way to look
at the syncros and tell if one or more went bad?
thanks,
Bill Edison
