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.

Norman, OK

Can you run it for a while to wear the disc in??? might be a bit too thick ?

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.

Way too much grease on input spline area

Orangeville, Ontario. CANADA

Technically that is the wrong throw out bearing too

Orangeville, Ontario. CANADA

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!

No , I think the short bearing is correct, I will get a picture of the correct bearing. gotta go to barn and get one

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

Lube isn't causing clutch not to release BUT may in the future get on the friction surfaces that would be bad

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 incorrect 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, they just want the $$$$$$

Orangeville, Ontario. CANADA

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 but I like to only put the clutch in once and not have a comeback

Orangeville, Ontario. CANADA

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.
