The brushes are avail. from NAPA auto. I don't have the P.# avail right now but if anyone needs it I can post it.

the commentator is avail new. . It's fairly easy to replace and not expensive.

When I rebuilt mine, all cost's combined, bearings, brushes and comm. was approx $50.

I did not look into replacing the diodes but I'm sure they can be replaced. If they where bad, you'd know it.

One thing I did was took sandpaper and lighty cleaned the armetur and stator sufaces and then painted them to protect them from rust.

Good write up, let us know how it works

The Diodes often fail. They need to be disconnected to measure.

Never use emery paper on a commutator or slip ring. The abrasive will embed itself in the copper and the brushes will fail much faster. I used to work at a company that rebuilt motors.

What's the proper way to test the Diodes? I'd like to try

To clarify, I didn't sand the comm. that the brushes ride on, I sanded the armeture with the windings
