Hello Gary and thanks for the timely advice. I hope to set my new bushing
this weekend. I had to cut the old one out w/ a piece of hack saw blade
(the grease/hyraulic removal method would not work even after more than a
dozen tries). I am pretty sure the new bushing is the same length, but, for
an eighth of an inch I had better check it again. I did not think it would
be a problem especially since the previous owner did not even have that
thick bellhousing plate installed. I found it in the trunk. So how did you
get the bushing in an extra one eigth of an inch if it was already resting
against the stop? Larry.

Subject: Clutch release problem found
A few days ago, I posted a message requesting ideas for the cause of a
newly installed clutch that would not release on a '68 1600. Thanks to
all who provided feedback. We pulled the engine again last night and
found the problem. It turns out that the problem was unrelated to the
clutch. The tranny input shaft was binding in the pilot bearing. With
the new clutch, we also installed a new pilot bearing (the needle
bearing type from NISMO). We installed it to the same depth in the
crank's hole as the original pilot bushing. But it needed to be 1/8"
deeper in the hole to avoid the tapered diameter section on the tranny
input shaft. The problem had the symptoms of a clutch that would not
release because the tranny input shaft always rotated with the engine
crankshaft even when the clutch was released.
I wonder who holds the record for R & R'ing the same roadster engine for
the same problem. I don't want to compete for the title even though
I've had my share of practice lately.
