Roller bearing tolerances
I'll try this one in here. I'm restoring my brakesof my side carand I need to see if the roller bearings in the brake hubs need to be replaced. Does anyone know what the sizes and tolerances should be? I have a 1930 VL with side car. Not much literature out there that I could find. According to the parts book it is part number 304-15 and is listed a crank pin roller, .360" long. Anyone have any other info
Thanks
Peter

Here is a bearing cross-ref that I build on from time to time:

It's in no way complete. Just a work in progress. It does, however, list your bearing and it's uses that I've found. If you have some way to lap your bearing race true, I would say do so to set it at an0.0008" clearance. But, if not, try to find a roller oversize that will bring it to a 0.001" fit, unlapped. I can get just about any of these rollers, and some in oversizes that the OEM manual does not list. Let me know what you do.
