inspection covers, screws, and gaskets from each
end of motor.

being careful motor lead terminal (T) remains in

gouging. Black color on commutator is normal. Have
commutator resurfaced by qualified motor repair

motor; check both sides. Brush Repair Kit 234037

One brush has a wire on top for brush wear sig-
nal. Note which side of motor it is on. Unplug at
