Removing bearing inner races from shafts.
Hey guys; Anybody have any good ways to remove inner bearing races from shafts? For straight through shafts and small shafts I've got no problems, just use a zip disk on a grinder, cut them almost through and break it with a chisel or press them off. But bearings against shoulders are a headache because you can't cut them right to the edge, you can't get behind them with a chisel or you damage the shoulder, heating doesn't seem to help and they are to large to get into a press. I e smashed a few but that doesn't seem to work on most, espeasially the large ones (I'm fighting with the outer wheel bearing on our 8970 right now). Do induction heaters work for something like this? Or is there a trick like welding around the inside of the outer race to remove it from the bore? I always have trouble with these, I always get them but there must be a better way.
