Larry,
Thanks for the tip. I am planning to change the master cylinder
and replace the clevis pin instead of rebuilding the mc so that should
eliminate one pivot point as a problem, assuming the pedal linkage holes
are not slopped out. I wasn't thinking about the other pivot points.
However, you can't check the pushrod in the slave cylinder and fork
pivots without pulling the engine can you? Also, being a pessimist,
assuming this doesn't cure my problem, how do you know when the throwout
bearing is gone or does it generally outlast the clutch?
TIA
