Just wondering what causes the wear in that specific location. I've seen a few bearings worn down to the copper, but none that were done this "neatly". I can't catch a nail on any of the surfaces.
This motor had 180k on it and looks really good considering. Not bad for $200.
I may toss in a new set as they are very cheap, and I'm not going to be gentle on it.
I was just thinking what ever caused these to wear this way may just wear down a new set as well.
