Hello I had the hardest time removing a bearing. I managed to to remove a retaining ring with snap ring plier but well I had to forcefully damage that out. But when it came time for the bearing separator all that happen was the bearing exploded and what was left was the bearing race.
It needs to be heated with a torch to expand it a bit. The shaft might need to be cooled as you do this so it doesnt expand with it. When putting the new bearing on often the shaft would be put in the freezer for a while to get the bearing in place with the least amount of stress to it.
Heat the bearing race with a propane or MAPP gas touch. Get it as hot as possible as fast as possible. If you make a red spot on the race that's OK in fact it won't hurt a thing. If you work fast, take a good cold chisel and hit that spot. Hopefully it will leave a mark on the race and that will in turn swell the race a bit loosening the fit.
TIP: If the outer race is stuck in a bore AND you have a welder, weld on the inside of the outer race where the balls run. Let cool and the race will fall right out. As the weld cools and shrinks it takes the race with it.
