I restored my 2 speed motor myself. It wasn't very hard to do, but I did need to fill pits with a high build primer. I separated the motor from the gear section and had a local electric motor repair business check out the motor. The motor and gear section were reassembled with pop rivets and then I filled the centers in to make them look like a solid rivet. It can be difficult to track down the original rubber mounting isolators. The rebuild process is easy.
The motor looks great. After I had to take mine apart to repaint it I also realized there's not much to a 2 speed motor so most people could restore one themselves.
