if you can get into the housing, the motor will be held down w/ screws to the frame w/ connectors running to a pcb of some type. just disconect the chain/s,take the screws out and undo the connector wires either from the pcb or the motor itself.

Well, I was a little off. Apparently the shaft where the bearing goes is worn down, thus the loose bearing. So, the shaft has to be "metalicized" or something like that. Not quite as cheap of a repair as I had hoped for.
