Man, the motor had 2 posts (front and back), and I had to remove the back HUGE spline gear thing on the "back" post in order to get access to the copper bars that the carbon brushes slide against (they had all that crap on them). I figured I could take it to a real motor person, but then again, hard plastic SOS pads only cost $0.99. It worked really well. It's now very smooth. Not perfect, but almost perfect. Good enough for government work (I'm a government employee I think. I substitute teach)
Removing that back post was like giving birth to a cactus. My 3 foot long crow bar came in handy though! ha!
The brushes were nice and long still. Now I know how to change the brushes. Really a very simple system, DC motors. Not many parts at all. The brushes were H-100's, whatever that means. Now I'm trying to put it back together. I hope it works once it's back together again.
