[Healeys] Bearing Cleaning

[Bob Spidell]

Hadn't thought of that, but it's certainly a good reason.  I've always assumed it's because, while the bearing and race 
surfaces are hardened, the hardening process may only be a few microns thick.  Any metal-to-metal contact could 
compromise that hardened surface, and cause premature failure of the bearing ('accelerated wear').
