I agree with Ron, if the spun bearing didn't damage the crank beyond the point of lightly polishing it then it should be servicable provided the clearance is still within specs. If your worried about a crack in the block or in the cap or whatever that can be checked for with everything together. There is a set you can get, I believe through Goodson, that is comprised of two magnets, one with a "active" North pole and one with a "active" South pole, and a magnetic/flourescent powder. If you place the the magnets on oposite sides of the block it basically polorizes the two sides of the crack, in effect turning it into a magnet. When you sprinkle the powder in the area in question it will be drawn to the crack. I watched the block man at our local machine shop use one of these sets the other day on the block he was getting ready to work on. It was amazing how the powder went straight to all the cracks, even the ones that couldn't be seen.
Good luck with your repair.
