There are still a few days till Tracy returns, so perhaps some of you
who have already gone down this path can assist me.
I am in the midst of installing the RD1-C drive and have aready made one
screwup.  I assembled the drive to determine fit and everything was ok,
so I removed it and started the final reinstall with sealant, grease,
etc.  With grease on the pilot bearing, air traps behind it and when I
push it in and release, it comes back out.  So I decided to use the 12
bolts to pull it in.  With grease on the thrust bearing, it stuck to the
adapter plate and was pulled off its location on the input shaft.  It
then slid down and was trapped (pinched) by the input shaft when I tried
to pull it in with the quarter inch bolts.  Crushed one of the
bearings!!  :>(  This happened just after Tracy left for vacation, so I
have had some time to think about what I did wrong...Not much joy!  I
plan to not put grease on the adapter plate side of the bearing this
time.
What can any of you suggest to me?  I would hate to go thru this again!
BTW...This is just at the location in Tracy's instructions where he says
not to force anything...I now have total understanding about why!

Also,  Tracy suggests that we put everything together and rotate the
assembly to center it, then torque the bolts that hold the damper to the
flywheel.  I can barely get any kind of wrench on the bolts, let alone a
torque wrench!  How did you guys accomplish this task?
Thanks for the help!
