The following will do it: Take pictures!!! Clean with Electric motor cleaner spray.
Remove the bushings in the drive housing, and brush end frame. The blind hole can be difficult, use a good hacksaw blade cut to a 45* angle to cut through the bushing. The drive end bushing will push out with a small socket or square end shaft that is correct to push on the diameter.
The armature should be true and flat. A lathe is best. A drill press is next with a sharp flat file, followed by polishing with 400 grit to smooth.
The mica insulators between each segment of the commutator should be undercut. It can be done with that hacksaw, but is easier with a Dremel and tiny cutoff saw Make a jig to V the commutator, and hold the tool in alignment. Cut only 1/32 deep below the copper.
Purchase a new style cushion drive pinion (small wimpy looking spring, much better design)
Reassemble with moly grease in the bearing pocket and in the drive end bushing.
Get help (four hands) or use stiff wire to hold the brushes back while putting the armature into the brush end frame.
Put on the band and paint it black. Best of luck. Jim
