The top motor brush has been loose and is worn unevenly. Should i just keep it the way it is right now?

There is a thick coating of this black stuff all over the motor.

I'd dunk that in a jar of tar/grease remover (or turps) for a day, then shake and repeat. Then pull out any hairs, threads etc, try and flick the gunk out with a screwdriver, spin the bearing in the grease remover then let it dry. Bit of wire wool should clean thetop up nicely enough. Then re-pack with grease. | ||

It looks press fitted, and I've ruined bearings in the past trying to get them out! Pick the worst out with a screwdriver and soak some oil in? | ||

No idea I'm afraid! If it's pressed in I'd say regular, but that's based on no real knowledge at all! | ||

Okay I will go to my local ace hardware and see what they have. Is it possible to cut motor brushes down to size? | ||

300
I restored one of these many years ago, the brass brush cap is held in by a little circular piece of metal that slips in behind the flange on the end of the carbon brush housing tube. They are very easy to loose! I may even have a spare somewhere. As for the "tar" its a combination of old grease, carbon dust, and just plain dust. It cleans of easily with electrical part cleaner or even carb and choke cleaner. I would clean each piece individually. As for the top bearing they are very well sealed in there. Just flush some fresh, clean electric motor oil into it. I like to clean the brass sleeve in my sealed bearings with a q-tip lightly saturated with electrical parts cleaner, that way no stray dirt is clogging it.
