How far should the clutch slave piston move the fork?

Just put the tranny back up after replacing the pivot ball.

I greased the pivot and the shaft that the throwout bearing slides on and checked to make sure the TB spun easily.

I did not check the pilot bearing BUT the clutch/etc are all less than 5K old(ACT flywheel and heavy duty PP and clutch).

Then rebuilt a master cylinder and bled the system.

Car will not shift while running.

How far should the clutch slave piston push the fork? Mines moving it about 1 inch.

I'll have to check again to get exact distance.

Anyone care to chime in on whether that's close to normal?

Your pivot ball broke, right?

I wouldn't have pulled tranny on and off without checking the pilot bearing. A bad pilot bearing can do just what you are describing.

An inch is fine, a little more or less depending on the freeplay

+1 to the pilot bearing.

The pilot bearing can be destroyed while putting in the transmission, especially if you use the ole 'get a bolt in and use it to pull it in' method.

bit the bullet and pulled the tranny today
here is what I was welcomed by.

Yup, it was pilot bearing. It grenaded.

There's a needle bearing sticking to the input shaft.


One obviously at the end in there.
