What would cause this weird bearing wear?

I have seen real good and bad new from the factory and that is on all the big three manufactures during the seventy's and eighty's because of there interest in increased production and less quality control. A part that has been rebuilt should have been checked for these type of problem's and a quality machine shop should keep there tool's sharp and true also. Quality control is what we as consumers struggle to deal with and makes our project's harder to do-this makes my head hurt:banghead:
