You will need to get bearings to match the align
boring and grinding you have done. You will need to
take the case and crank to a machine shop to have them
look at it. If the damage is minimal, they can bore
and grind each one .025mm (.010"). If the damage is
substantial, they will have to bore/grind .050mm
(.020"). The case can be ground to one dimension and
the crank to another - they do not have to be the
same. Once this is done. you can order your bearings
and begin the rebuild.
