Re: clutch woes (corvette184)
I doubt the clutch is defective.With the different tranny you may need a different throwout bearing. Have you checked the fork,pivot ball for problems? :cheers:

What do you mean it "didn't feel right" when you used the prybar?

Re: clutch woes (corvette184)
Have you had a look at the fork movement when someone depresses the clutch? I've been messin with cars for over 25 years and never come across a pressure plate that didn't depress. I'm not saying its impossible, just very unlikely. I would take a close look at all the other possibilities. :cheers:
P.S. The shop that did the work should fix the problem. You paid for a job that was not completed.

Re: clutch woes (corvette184)
How is your peddle pressure? If it is hard maybe you do have something binding. But if it is week maybe you have air. I had to on my friends 84 and my 92 take off the clutch slave cylinder and point the bleeder screw up making it the highest point in order to get all air out. Just throwin ideas out there.

Re: clutch woes (BAM92)
It could very well be the flywheel. The shop I took mine in to took off .010, and I notice a big difference. The clutch doesn't release until the pedal is 90% down. Too much cut on the flywheel move everything forward away from the t/o bearing, so you need even more clutch movement to move the pressure plate enough to disengage.
I'll try bleeding it more also... that was quite difficult.
Does anyone know what the return spring in the slave cylinder is for? It sure doesn't return the piston at all. The piston is very snug in there, so I don't see the point. I guess if it actually moved the piston, then the t/o bearing would rub on the pressure plate all the time?, which is bad.

Re: clutch woes (corvette184)
I had a bent clutch fork in mine, may be worth looking at. I must have bleed that system 100 times, didn't do one bit of good, the fork just kept bending more and more.

Re: clutch woes (Aaron71771)
bled it so much that i never want to bleed it again........did all the bleeding tricks and i get almost an inch of travel at the slave...i will pull aaprt and check all possibilties.....my first thought is they let the tranny hang on the clutch disk and bent it.....i did this once as a teenager on a 70 chevelle....bent it enough where it would not disengage....i never thought of a cracked fork...which is the mushy feel i get when prying on the fork....ps the shop is a client of mine from work and i would hate to lose a high dollar client at work for a measly 1500 repair job of my own......my job has to come first on this one....otherwise i never would have paid or accepted the car back

Re: clutch woes (corvette184)
Wen I put a new fork in mine I had just over 1.5" of slave travel; compare to less then .5" with the old fork. If you have less then an inch, the fork is worth checking. Tho, I would expect that yours is different then the ZF. You might want to check with some people with your type of setup and see what kind of travel they are getting.
You could also drop the slave and push the clutch in to see how hard the slave is. I don't think there is a whole lot to bleeding a working system.

Re: clutch woes (Aaron71771)
Isn't the t/o bearing supposed to move like 1/4" or something after contacting the pressure plate? I believe that's what I saw in the shop manual, I'll have to double check. An inch in the slave sounds right though. It shouldn't matter what transmission's in there, the bellhousing is the same, and the clutch set is supposed to fit, right?
