I've read in many different places that if you take a hub apart and see damage on the cups, cones, or bearings (may god have mercy on you if your cups are damaged) That they must be replaced.
I recently bought a used bike that had a lot of miles on it. There was a tiny bit of damage on the cones in the rear hub, concentrated within about 1/8 of the race.
That seems to make sense: The wheel spun very freely, so it was well-tuned, and the top of the cones took very little wear. The damage developed where the rider's weight was: on the bottom 1/8 of the cone.
So I'm wondering if I can get away with simply rotating the axle so that the cones have the damaged side up, and the good side down. That way the damaged side will be supporting an insignificant amount of weight (and not messing the balls up), and my ball bearings will have the pressure on them while they're rolling over the good part of the cone.
Does that sound like a hack that will work?
