Ed, there is a difference between the older crank and flywheel and the later
crank and flywheel. The older is a longer snout and the flywheel is more
dished and lighter. You can't mix the components without doing some major
work to the clutch/transmission.
Do not mix the pilot bushings! I imagine the longer one could be cut to fit
the later crank, but why? Just get the right one. They both fit in the same
way and I wouldn't want to take a chance of the shorter one not holding the
input shaft properly. We've heard of guys developing transmission leaks
after they didn't replace the pilot bearing with a rebuild or even a clutch
job.
Easy to do right now, pain to do later.

Subject: TR6 flywheel question
> I have a couple of questions aimed at those who know more than I about TR6
flywheels. I know there is an early, '69, flywheel, and a later, '70-'76
flywheel. I also understand that the early uses the smaller pilot bush that
goes into the crankshaft, while the later one has the bigger bush sandwiched
between the crank and the flywheel. My questions are this...is there a
difference in the offset of the flywheels that would make one fit and the
other foul the engine backplate? Are the cranks different? Is the hole that
the small bush goes into on the early crank carried over to the late crank,
even though the bush doesn't go into it? I have flywheels that I don't know
what they are, and I need to get my s@*t straight. Thanks for any help I can
get from the list - Ed
