Hey everyone, just a quick questions, whats some tell tale signs that the bearings need to be replaced? I'm currently stripping down my 45 for a rebuild, and am going through it all. I plan to replace the bearing that goes on engine clutch, at at least the bearings on the blade cutter for that perfect finish! To me the rest of them seem in pretty good condition, no play, spin freely etc! Thanks for your help in advance!
