if you have the old on out and shave it don so it is no longer press fit, (drops in,falls out) then you can use the old race to tap in the new bearing. I've done thing for toyota bearings, make them @ 1mm undersized, cut two tabs in the to ease pulling them back out, and then use them to hammer in the new bearings.. it works and its "free" tools, that you might reuse.
but i also have a press.
