Got it loose..! This had a couple of round brass pin that went into the
rotor and I though they were part of the assembly, but were not. A little
back and forth and she came out. Im as happy as if Steve White gave me his
big inductor. Thanks again.

Shaun....have had the same problem with 4 different units. The brushes
corrode into place and allow arcing to the windings and the burn a turn.
You have to gently tap back and forth to get it loose......take you
time......it will come free.
When you are loose take the sides and lightly sand the corrosion off so
the brush so it slides freely in the slot. Might have to sand the slot
also. A nail file comes in handy. No oil! Can use graphite powder for
lube.
