Replacing sealed hub bearings

Woohoo, I just checked my hubs and they use sealed bearings so I can annodize them without worrying about steel cups. How hard is it to remove and replace these bearings? I can't immagine it is too difficult.

They tend to be press fit, so you're going to have some fun popping them out and putting them back in, I suppose.

It depends on the hub. With the correct tool, pressing bearings in and out is a 2 minute job. Without it, it's much harder, depending on the hub and tools you have laying around. Pressing them in is quite easy, pressing them in without damaging the bearings is much harder.

A bearing puller tool makes it easier to remove the cartridges without damage. To replace them use a bench vise with soft jaws to press them back in.

Some hubs have the bearings an easy press fit and others are a hard interference fit. If you drive them out, or press them back in with any force on the inner race, you will ruin the bearing.

I would not reuse any bearing that has been pounded or yanked out. I remove Mavic bearings by tapping them out with a large screwdriver, inserted from the opposite side. I install the new ones using a socket wrench that is just slightly smaller than the bearing OD. The force should only be applied to the outer bearing race.

Have you checked into the cost of stripping the old finish off your hubs and reanodizing? My guess is it might cost more than a new hubset, unless you've got a friend in the business.
