Now I’ve polished it with silvo, I didn’t have braso, and rinsed it clean with contact cleaner.

So after our long discussion, where should/shouldn’t I grease it and what grease do I use?

Man, you outdid yourself. You could put that in a display cabinet. It shines!

Sorry of I have slowed you down, I understand your car is off the road right now, and did mine from start to finish in one sitting, on an afternoon, both sides; if one fails, the other will follow. And for me, I think one totally stopped (drivers side) while the other maybe started to intermittently fail. I should of written up what I did when I originally did it, so its from a memory and what I would do now.

So what the numbers mean:

1. the spiral insert / plastic worm drive. I cleaned it out the old grease by twisting a clean dry rag into the gears. In a perfect world, I would of repacked it with NON electrical grease that would not degrade plastic/silicon. As I thought it was only going to be temporary fix (I never expected 10+ years), I just used some grease I had (not that I would admit to it, but I would not be surprised if it was simply vasoline from the bathroom.... 🤡)

2. More cleaning and replace old grease with plastic safe & non-electrical grease

3. This is where I polished and put a light coat of electrical conductive grease. It was the gouges in your photos of the polished surface that the grease was hopefully to fill and improve the transfer of electricity, And more focus in the band shaded by wear in your before photo

4. Just a good clean (the case/magnets were clean well when done), I don't think I greased it at the time. Maybe a light non electrical grease MAY be beneficial it in case its spinning while going over a bump, and hits the magnets. IDK

5. This is where I went to town with the electrically conductive grease. This is the ground contact, and if the point is worn down away, the grease makes up the gap, and it is spinning metal on metal with no bearings. Hence the possible wear in my mind.

This still makes me scream. Totally unnecessary.

And what? Why do you think there are two brushes running on the commutator bar? There is no "ground" that matters on the shaft of the motor.

Ok. It’s working. I only greased the worm drive gear though. I built an electric motor in high school and GTSBoy is correct there is no earth grounding point at No.5 just the 2 brushes. I thoroughly rinsed out any grease and grime with the contact cleaner.

I don’t know how you managed to pull the brushes out to stretch the springs I couldn’t grab them even with pointy noses pliers and the graphite brushes felt soft and I didn’t want to damage them.

So far it’s working again. I’ll report back here as soon as it stops, if it stops. Hopefully it lasts for 10 years. The drivers one gets the most use. My passenger one is fine though.
