The motor brushes are angled for clockwise rotation from the drive end, 12 degrees as an estimate.

I know that I can reverse the polarity on the armature to change the direction, but from what I've read that would wear the brushes more quickly, spark a lot if the brushes are advanced, and likely have a lot less torque.

So is it a big deal to dis-assemble the motor, remove the brush holders, and mount them for reverse rotation?

If that is not over my head, how would I figure out the correct advance for the brushes in the new direction?

Or should I just reverse the armature leads and accept the reduced performance and life of the motor ... since it presently works as an electric motor right now and there is a good chance that it will never work again if I take it apart?
