Hi Gary,
I have never heard of a carbon release bearing running on the clutch
diaphragm fingers and surviving for more than a few seconds. The TR5-6 used
a clutch cover without a release bearing plate but it uses a special ball
bearing to run directly on the fingers.
I would suggest that you replace the cover rather than try to fix it. It is
a lot of work to get back in there if the "fix" doesn't work out. I seem to
remember that the release bearing plate is held in place by a ring pressed
on from the flywheel side, but I may be wrong.
There should not be a plate of any kind in the area of the pilot bush. It is
just pushed into the end of the crank. The usual method of removing it is to
thread a large tap in then pull on the tap. Alternatively you can fill the
bush with grease then get a shaft which is a tight fit into the bush, sit
the end of the shaft on the surface of the grease and give it a sharp whack
with a heavy hammer. (wear safety glasses). The bush will usually pop out.
There is usually quite a bit of side to side play in the gearbox front
shaft. It is really only restrained by a ball bearing and the needles on the
end running inside the output shaft. Once installed the shaft is supported
by the pilot bush so the play is of no consequence. If however you find
metal particles in the overdrive filter or on the magnet the needle rollers
may be breaking up and I would definitely recommend stripping the box just
to make sure all is well.

Subject: BJ8 Help needed!
I have been having a problem with the clutch (or so I thought) on my BJ8.
Part of the new years resolution what to get this fixed. Took the tranny
out
yesterday and began checking things. First thing I noticed was that the
release
plate was missing off the clutch release fingers. It is a Borg & Beck that
has the 3 fingers. So the release bearing was riding directly on the
fingers
rather than the proper plate. Keeping in mind that this is a car that was
supposedly restored by a professional when I bought it I was a little
shocked to
find that. Fortunately the fingers appear OK so now I need to find the
plate
and clip springs to hold it in place. (3 of them). Any leads or offers
considered!! The second thing I found was that the pilot bushing going into
the
crankshaft appears to have been damaged. I have removed the flywheel but
how do I
remove the plate screwed into the crankshaft and then replace the bushing?
Lastly it appears that there is more movement in the pilot shaft coming from
the transmission than there should be and it looks like the seal may be
starting
to leak. Obviously I will replace the seal but is there a bearing or
something else should be considering for replacement while I am in to all
this?
Many thanks,
Gary Fuqua
Ps...Norman, I have looked high and low for my copy to Tech Talk without
success so guess you'll be hearing from me for another copy.
