If you remove either cover do so carefully as there will be washers/spacers/shims on each end of the shaft, on the inside, up against the bushings. It's important to pay attention to the order of these washers.
The attached photo was helpful.
I took the motor apart. The commutator had no wear. I did turn it in my drill press and clean the carbon off. I bought brushes at the hardware store, but they were the same length as the original brushes which I re-installed. It is inconvenient to install these brushes and reassemble the motor. The later style motor shown in the video would be an improvement The motor runs a little quieter now, but not what I want. I'll probably buy an L frame motor from Amazon. Maybe an electronic controller. Suggestions for the controller would be appreciated.
