I just wanted to add a concluding thought about the pins.  The question
was whether they were necessary or not.  Afterall - the clutch will bolt
on in 6 places - right?  That should be straight enough - Right?  No?

Not!  I had no pins in my flywheel and it is obvious what happened.
Something went awry and did fry my pilot bearing and scortched the
flywheel.  Missing dowels are as good a reason as any.

Let me explain.  As I was putting the mastwerpiece back together I came up
with the question.  Lock-tight or not to locktight the flywheel bolts.  I
didn't have any - and I was almost finished.  I torqued to the spec 80 lbs
withour and left it at that.  Then the clutch.  I lined it up, and put a
couple of bolts its.  This time everything said Lock Tight them.   I
wondered if I could get away with it.  I read the torque spec.  Tom's page
recommended 20 pounds and Bently 18.  WOW I thought.  What would keep that
thing from moving around like an out of control merry-go-round?  I mean
the flywheel gets 80 lbs and the clutch only 20 lbs at best?

It cried - "SOMETHING IS MISSING."   So I go back to Bentley and there
they are.  Three pins on the flywheel.  YES they serve as a guide to line
up the clutch.  But my guess is that they hold the clutch in place
centrifically as well.  So they would seem an absolute must to me.  Make
sense?

So- It appears that it is my task to fabricate something - at the
suggestion of the machine shop.  I will share what I come up with - when I
come up with it.

Thanks for continued feedback.
