There are times when you need to pull a bearing off an assembly, but either don’t have the proper bearing puller, the bearing cannot be grasped well enough to pull it free, or a slip fit bearing has been overheated and its inner race is frozen onto the spindle or other shaft. A solution we’ve used is to take a cutting disc on a rotary tool or hand grinder, and place one or more notches in the inner bearing race after removing the cage and rollers. A smack or two on a notch with a cold chisel should fracture the race and allow for its removal. We once removed a frozen wheel bearing race on a truck spindle on the side of the highway using a hacksaw and chisel. It was super slow, not fun at all, but it did eventually work to get the race free.
