That's good to know! At least it saved you the multiple times removing
and reinstalling the gearbox before you solved the problem.
Cheers,

Darrell,
This all sounds too familiar. When I first built Tiny Tim, I used an
aluminum flywheel and a GT6 gearbox with the input shaft cut down for
use with the Spit engine. When I put it all together, I would get a
noise that sounded like the throw out bearing. So I took it apart and
examined everything and found nothing wrong. I suspected the problem
was being caused by flywheel being much thicker than the steel one and I
fabricated some shims to increase the clutch spacing in hopes that would
fix the problem.
No Dice!
This went on for at lease a dozen times pulling the gearbox out
(something I was getting darned good at by then)! Finally, I noticed
that there was some wear patterns beginning to show up at the hole in
the flywheel where the input shaft end goes through. After looking it
for an extended period, I determined that there was rubbing there by the
input shaft and the problem was easily resolved by chamfering the hole
so that there was proper clearance.
I hope this helps.

Joe,
Thanks a bunch. Fault Diagnosis on the 70 MK3
is complete and it is exactly as you said. I feel a whole lot better
although the gearbox needs to be in the car and not on the bench. Still
have to pull the Tilton and Fidanza Flywheel out and get the hole
machined. This will only be the third time out and in so that's not
real bad.
Cheers,
Darrell
