Clutch Disengaging issues - ZR-1 Net Registry Forums

LGAFF · 08-15-2014

Since I put the 90 back together, the clutch has been less than perfect...sometimes not disengaging....I redid the clutch once with some improvement and no significant issues.

Well two weeks ago the clutch went back to not disengaging and not allowing me to shift when the car was cold and parked on an incline or decline. (while running)

For shifts and grins I went out last night and pulled the collapsing rubber seal out of the master. The issue is not completely gone.

Will see if it lasts

Fork got a curve in it?

LGAFF · 08-15-2014

Not sure whats going on....going to change the master and slave again to see if it helps. I had someone else do the clutch as I had my lift occupied by the Callaway.

Lee,

Are you referring to the rubber seal in the reservoir cover, or something else?

LGAFF · 08-16-2014

yes, initially it worked, but apparently a coincidence that the issue went away

Lee,
Must be something in the air here in CL. Last Sat. I wanted to take the Z out and couldn't shift into reverse. Reservoir was bone dry and black crud at bottom. I did not put the black cup back in, not sure what it's purpose is. Is it OK to leave it out? With it in there is now way to fill fluid up to the fill mark.

John you have a bad master or slave....give me a call

LGAFF · 08-16-2014

Changed slave....not sure it helped....

*push in clutch....single mass rattle stops
*On jack stands the wheels will spin when in gear with clutch in
**Will continue spinning even in neutral
*Hit brakes in gear with clutch pushed in....wheels stop even after brake releases

Been through 3/4 slave/master sets no changes.....

All new sycros last year

Could be fork, or pivot I guess

Lee,

Have you checked to see that the clutch pedal is not bent? This was the problem on my 84. Clutch pedal was straighter than it should have been and would not disengage clutch or did so reluctantly.
