Default Clutch Pedal Travel Problem

I am restoring a '36 truck. I recently pulled the engine and transmission to do some work on the frame. Decided to rebuild the transmission with help from Van Pelt's (actually spoke with Mac himself). The transmission rebuild went great. The pressure plate assy seemed perfectly good and the plate was nice and flat. I purchased a new clutch, pilot and throw out bearing and installed everything back together.


Here is my problem. When I bolted the engine/trans assembly back in the truck, I now have about 3/4 of an inch of travel of the throw out bearing before it makes contact with the pressure plate fingers. This three quarters of an inch of travel equates to 8 inches of pedal travel! Way too much.


Here are some answers to questions that I'm sure to get:


Everything is stock
Clutch is not in backwards
Clutch lever on side of trans is not on backwards
New throw out bearing is a mirror image of the old one
Engine stay rods are in place
Pedals and linkages were not removed or replaced or adjusted
Transmission bolted back up to the engine easily and fully
The engine flywheel was not removed



I tried adjusting the clutch linkage but the long travel does not change...the distance between the throw out bearing surface and the pressure plate fingers is still too far.


I do see that the pressure plate fingers have an adjustment screw on each of them. But even if I turned them out toward the bearing, there is probably only a quarter inch of travel and maybe not even that.


Anyone have any insight?

Are you using a new pressure plate and clutch disk or the old pressure plate with a new clutch disk?

I seem to remember one time that there was a rash of clutch discs that were too thick and wouldn't release. The disc being too thick caused the pressure plate fingers to be recessed.

I am using a new disk but the old pressure plate. The old disk was in really good shape with minimal wear, but it just made sense to replace it. It looked nearly identical to the old one...thickness included. Thanks for the input tho.
