- Below the Mackinac bridge
Some guys have seen this, others might not. When you can't get to the back of a bearing outer race to push it out, you can fill the bearing cavity with oil and tap a close-fit shaft into the center to lift it out. In this case I had two bearings in a housing on opposite sides of a step, and couldn't get to the outer races. I put a shaft in the lower bearing and hammered a Thompson shaft into the upper. The resulting pressure under the bearings lifted them just enough to get a screwdriver onto the outer races and tap them out. They need to be sealed or shielded bearings for this to work well, these seals blew out pretty quick from the pressure.
