alternate bearings

[PAULYBOY]

what about spraying the bearing with a good dose of freon?

Thanks for the tips guys. I finally got them out. I cut as many grooves as I could with the dremel, arches going back & forth across each other, until I got completely bored. That heated the metal until it was smoking. Then I doused it with penetrating oil, which cooled it off quickly. Finally I was able to pound them out from the other side. I don't know if it was the heating and cooling, or the weakening from the grooves, or a combination of both that did it.

I have a few grooves & pits in the swingarm tube now. Should I smooth them out before putting in the new bearings? I don't want the grooves to accumulate rust and make the new ones impossible to get out years from now, but I also don't want to make the tube oval and have loose bearings!
