Hi!
Pullers should not be used when replacing bearings in an aluminium case! If done that way you will damage/wear the bearing surface and the bearing will sooner or later come loose.
Only heat should be used! Either an owen or a propane torch!
It doesn't matter what happens to the bearings if that were true. You use a puller to get the drive washer off. Anyway, aren't those bearings getting tossed when you get them out?
