pressure plate

[les harris]

I have seen a post about pp finger measurements can someone tell me what they are measuring and how ? I thought all you have to do was bolt the pp to to the flywheel evenly I did that and the fingers would not release with the throw out bearing fully retracted. I made sure it worked while I had it on the floor but when I installed the motor and trans as one unit I had no pedal after one push on it the pp hung up. I took the pp and tested it on my hydraulic press and it worked now I am at a loss as what to do to make it work.

Possible that the throw out bearing is not tall enough assuming clutch rod is giving you full stroke without excess clearance.

When I did mine I used my "surface plate" (a 2 in thick piece of 12"X12" granite ground and polished dead flat). I placed the pressure plate on the surface of the plate and measured the height of the fingers with my digital calipers. Going back to my original thread, my initial measurements were 1.225", 1.180", and 1.175" from the plate to the contact surface of the fingers. I measured 3 times. While I would think a difference of .005 would probably be OK, but I don't think the .050 between the highest and lowest to be acceptable.

BTW, that clutch has ben in service for almost 10 years now, and it has provided excellent service; smooth, no chatter, and a pleasure to drive.
