 1) What is used to hold the pin in place? Locktite, Interference
fit?(hope not 'cause it ain't no interference fit anymore)

 2) Just how pricy is the rr main. I know it can't be cheep. That thing is
huge!

 3) Are the oversized bearings, oversized in the Id and OD. Meaning if I
need to clean up the flange and crank, can I find a bearing to fit?

Its been a long time since I have had a crank out, but as I remember the pin
slips in from the inside of the bearing & once the crank is installed the pin
cannot come out. The pin should hold the bearing in alignment with the oil
passageway. Sounds like your bearing turned inside the flange, sheared the
pin & blocked oil to the crank......not a pretty thought.

Very pricey, in the neighborhood of 200+ bucks. Again, I'm going off memory.

Not sure of bearing sizes.

I'll Soon to be getting a reminder of what the crank & bearings look like, as
the motor from the race bike comes apart.
