Has anyone ever renewed the 1/2 hub [3/8" axle] bearing path and brake drum surface on a Harley 45 WL ? I have rust pits in both side of my bearing surfaces where the ball bearings run and the brake drum inner surface where the brake shoes contact is heavily pitted. I worked in a machine shop for 3 years running a surface grinder and we dressed grinding stones to various configurations. My idea is to grind a shaft mounted dressed round grinding stone and gently renew the bearing races on a milling machine. For the inner brake drum surface I would assemble the inner bearings and hollow center shaft assembly and spin the drum/spool hub assembly on a lathe and retrue the inner drum surface. I would buy a new center hub assembly but OEM Harley hubs are $850 and I don't trust the ones from Tedd Cysle/ V-Twinn to be made correctly or the bearings races to be hard enough. Any thoughts or experience is welcome.
