Anyone have suggestions about bearings?
I figure that while the motor is apart, I might want to replace the bearings.
Doesn't really look like there is anything wrong with them, but the commutator doesn't look in great shape, and I figure the bearings haven't been changed since the commutator was new. On the other hand, are bearings in electric motors designed to last forever?
The only moving parts in the motor (literally!) are the two bearings on either end of the rotating shaft, that's it!
I figure that since the motor is apart anyways, now is the time for new bearings if I am going to do them.
Is anyone familiar with turning a commutator on a lathe? I guess this is what people used to do with starter motors to fix them. Put the motor shaft in a lathe, and turn down just a tiny bit off the commutator, so it is shiny and smooth. Nice, new, clean surface for the brushes to rub against.
Anyone done this before?
