It looks like there is some serious discussion now on "FC General Discussion" so I will post my question/problem here. I just installed a new 51/2" Tilton clutch on my Carbir Pinto. I can not get the clutch to release or slip.
This is what has been done in replacing the old 71/4" clutch
1. Replaced 3/4" master cylinder with a new 5/8"
2. Replaced Saab slave cylinder with a new Tilton. The piston that came originally with the kit was replaced with one that gave .200" air space between pressure plate fingers and the fully compressed piston.
3. A 38mm throw out bearing is used.
4. Pressure plate, disc etc. are all new
5. When everything was together, the cutch pedal was slowly depressed while trying to find the point where both output flanges could be turned with transmission in gear. (I didn't want to over extend the pressure plate fingers). During this process the cutch never disengaged/slipped.
6. I have around 1-1/4" of mater cylinder push rod travel and 1/4 " of slave cylinder travel. The free play between the slave cylinder and pressure plate is where it should be.
7. The clutch has been bled and re-bled many times starting at the master cylinder back to the slave.
8. The car is plumed in -4 from the master back to the slave cylinder. The Tilton slave cylinder is set up for a -3 fitting unlike the Saab which uses a metric to - 4 fitting. I cut and welded a -3 to a -4 fitting and drilled the hole to the -4 diameter. There are no leaks. Could this cause my slave cylinder piston travel to be affected?
I have had the transaxle, flywheel and clutch apart many times. Any thoughts or suggestions?
