Mike,
Thanks for the heads up on the bearing. I am not quite sure what you mean by
rotate the bearing in the fork. I hve installed the bearing on the fork and it
seems to rotate freely. Does the bearing actually make contact with
the surface of the fork?

I have used these successfully for a couple of years now, but my first
experience with it was disasterous. It caused me to totally lose my
clutch while sitting on the dummy grid at the annual six hour relay race.
(Long time members of the british cars list may remember my report)
I had to replace the pressure plate, clutch plate and roller bearing as a
result of the failure.
It turns out that the plastic casing (which is significantly larger around
the back)
can interfere with the throwout fork. This means that the throwout bearing
is
never fully dissengaged and spins at engine rpm. Also because of the
geometry, the pressure isn't uniform, but is only on the lower part of the
bearing.
This will overheat the bearing causing it to fail with melted plastic and
free ball
bearings. It will also ruin the engagement face of the pressure plate.
Fortunately, the cure is quite simple. You merely have to grind away the
lower rear
plastic until the bearing rotates freely in the fork. here is a very crude
ascii form

Does that make sense? Anyhow rotate the bearing in the throwout fork
until you are sure you've ground enough off.
Once you have done this, you'll have no problems with them at all.
Mike
