I had the opposite happen to my RR motor, The flywheel bolts got loose and screwed up my threads and now I need a new crank and Flywheel! I'm thinking that's what your'e gna have to do.

I do have 4 bolts that still bolt up and the other three I am drilling holes in and am going to try and back them out. I think I'll manage without changing cranks!

Although worst case I do have a extra motor laying around were I could grab a crank if needed, its old but with some cleaning and new bearing's it will be fine.

Alex, did you strip out the threads on the crank, cause an easy fix to stripping is to drill out the stripped threads with a slightly larger bit and then rethread it with tap and dye set. Although they are pricey.

Jon, you're on the right track, drill a hole in the bolt that's left and get a screw and bolt extracter kit. They are fairly cheap and simple. They have reverse threads so that when the bit goes in and tightens it backs out the stuck bolt. Also use some PB Blaster or some kind of chemical to destroy the rust, assuming that is your problem.
