Carbon Brush 384613-01

This part includes one carbon brush. Your tool will require two of these, and they should be replaced at the same time. Worn carbon brushes are the most likely reason that a motor is not performing as it should. The function of the carbon brushes are to conduct electricity to the armature. This is done through the commutator. Carbon brushes are constantly rubbing against the spinning commutator, and this is why they wear over time. For this simple repair, start by removing the motor cap. To replace the brush, remove the wire lead and tension spring, and pull the brush from the holder. To install the brush, place it into the holder, place the tension spring on the rear of the brush and reinstall the wire lead. The same thing will need to be done on the other side.
