This is my first post on this site and would like to share my experience. This motor is like no other one I have ever taken apart, once I figured out how it was put together I was able to get it apart. This motor was from a J head I picked up for parts, my guess is it was probably from the 50's. I wanted to clean it up and repack the bearings. The bearings in this motor are double row bearings on the shaft end this is a well built motor. Looking at the photos should help anyone that wants to rebuild theres and make sense of how it goes together. There are plugs on the top and bottom of the motor that can be removed to grease the bearings once the motor cover is removed this can be tried to quiet down a noisy bearing if you are unable or do not want to disassemble the motor.
