Finally split the case of a 0-320b3b that has been in my basement for years in a disassembled state. What should I look for to determine the condition of the case? I have looked it over and can find no cracks and the bearing surfaces are nice and smooth with very little sigh of fretting. Or should I just automatically bite the financial bullet and send it out for OH? If it does need OH will it still be able to use std size bearings? Thanks for the patience of the forum and the help.
