Okay, so here's the deal. The bearing in question is a needle bearing. The race is obviously steel... The needles and carrier have been broken out, and the "lip" on the race is about 75% busted off. The bearing was seated in a blind hole (no way to get to it). I need this ****ing race out of there. Cutting? No dice. Torch heat? Nopes. Hammering? Impervious. The hole the race is seated into is aluminum. Now, I need an idea of how to get this race out of there. I was thinking maybe a few s***ches with a MIG welder? That would likely cause the race to shrink a tad (read this online) and then it would be easier to get out. Anyone else have comments on this, or suggestions? (And no, I do not have a blind hole puller. There's no lip to pull on anyhow. haha)
If you are thinking about hitting it with a MIG anyway try tacking a bolthead to it then use it to help pull it. Just a thought, might not be practicle.
My first thought was to try tapping threads and running a bolt in for grip. but the race is probably too hard for a tap. How about a small grinder and grind away a groove down one side to weaken it to the point where it isn't a tight fit. Tracy
Mig weld a bead on the inside of the race. When the weld cools off, it will shrink the race. Last time I tried that trick the race simply fell out when I turned the piece over...
Weld shrinking should probably work, or maybe try the old- pack with grease and hydraulic it out-pilot bushing trick ?
