Disk in backwards? One side should say "Flywheel Side", but you probably knew that. Still, we are all only human and do make simple mistakes from time to time.

Disc is in the right way...the one I have (from Ken Hand) will only go in one way b/c the nose on the forward side of it would hit the flywheel if installed backwards. Ken also did my flywheel and pressure plate. It all seemed to go together easily, but I did not bench test the assembly before installing.

I pressed the pilot bushing (new) in to be 1/8" below the crank face per the shop manual. However I did not bottom it out, so I suspect it may be just up enough to bind the input shaft.

I did not measure the disc before install but it's binding pretty. Will try a 4th gear slip before taking the engine out but I am not hopeful. The clutch does disengage but something is dragging. Even when I overadjust the cable very tight (just to test) w/ the pressure point on the petal at or above the top I still get binding.

The pics I have of it before assembly are below. Unfortunately I did not measure the disc thickness.

Riveted center disc generally contacts flywheel bolts on late flywheels.

I think Mel has something there. This is supposed to have the taller bearing.
AMAZING WORK Nick. I wish you would hurry up and get this done. I want you to work on my car next!

Tim release brng is correct for late parts. Doubt that lube on splines is the cause, look at pic of disc on input shaft.

Look on page 111 of Clarks catalog. They have a table of TO bearing heights. Says the taller bearing is 60-63 and shorter bearing is 64-69. ????

Here are some pictures of the correct TO bearing for a diaphragm pressure plate used in a Corvair , the flat TO bearing that they all sell you these days is incorrectsad smiley The flat bearing is really only correct for 3 finger Long, and Borg Beck pressure plates.I only use this style, never had a problem with releasing.They sell you the incorrect one because they really don't care if it's correct or not, sad smiley they just want the $$$$$$ eye popping smiley

Sorry Mel that is early flat finger release brng. Late bent finger is what is pictured on the diff for bent finger diaphragm which is correct for his flywheel/cover.

Yes, Steve is correct. Mel + I are incorrect. The early flat PP needs the taller bearing. Nick, did you put your disc on the shaft and then put your shaft into the pilot bushing (and see if the disc when pushing it into the flywheel rubs on the flywheel bolts)?

I never ever use a flat TO brg on any Corvair diaphragm clutch whether it is early or late style pressure plate, you may get it to work most of the times , but it's not correct.This is why some 64 clutches will not release properly.Suit yourself eye rolling smileybut I like to only put the clutch in once and not have a comebackdrinking smiley

Maybe its the angle of the photos but it looks to me like the fork is not engaged in the groove of the TOB in the first two photos. Looks like it's behind the flange on the diff side.
