I spoke with a Powder Coater a few days ago and asked him if/how he protects bearing races & threaded areas in the frame. He explained to me that he uses plugs and that my races will be OK when he is done.
For anyone that has done this, did you replace the races even if the bearing and races were good?

If the races are protected and if there is no evidence of brinel damage or roughness in the bearings and if you remembered to keep track of which inner roller bearing component goes with which outer race... a fresh load of grease and proper reinstall should be just dandy.
Power coating can be a true PITA trying to refit parts in tightened up i.d.'s. I once had to painfully sand away paint from the edges of an aircraft's aluminum instrument panel that I had fabricated "just perfectly" before applying a finish... The instruments no longer fit. >:(

Yes, I planned on labelling all the bearings...but you just gave me another thought..to check the thread sizes of all the studs that I remove from the frame in case I have to chase the threads in the frame when it's re-coated.

Mike,
Before I PC'd my frame, I removed all the bearing races. I carefully masked all the bores and seats, and put dummy bolts and nuts in all the necessary holes. About the only places I didn't protect were the holes for mounting the relays and electrical bits along the backbone of the frame, and the teeth where the footpegs mount. I used star lockwashers for mounting electricals to be sure things were grounded.
