There is no relative rotation between pilot on input shaft and pilot hole
in crankshaft BUT The input shaft pilot should be a close fit because it keeps
the rear of the input shaft properly aligned. Don't wallow it out
indiscriminately. A small groove in one side (from the dremmel
operation) will not hurt.

The next chore was the removal of the pilot bearing. We
had
tried removal from several approaches without success.. The Harbor
Freight
pilot bearing puller is a smidge too large to go into the
bearing hole...
finally I re-read the RD1-B install manual and it
mentioned that a dremel
has been used in the past for stubborn ones. I ended up extracting the
individual needles with a scalpel and
needlenose pliers, collapsed the
inner race and yanked it out, then
ended up using a dremel to gouge the
outer race, then collapsed IT as
well.. Infortunately this gouged the
inside of the bearing channel in
the process, so I drum sanded rough
spots until it was finger smooth.
The PSRU pilot shaft was able to fit in
without difficulty.
My understanding of the
bearing removal is that it doesn't have to be smooth, just give clearance for
the pilot shaft since the shaft does not revolve in the bearing hole. Correct?
I had a slight drag when the re-drive was rotated so dremelled the hole with a
stone to give more clearance. What I don't understand is, why would there
appear to be runout at the pilot shaft of the RD-1?
