Starter Motor Overhaul (28-MT Frame and Field Assembly)

Brush Spring On The Post:

1. Install the brush springs using the following procedure:
1.1. Start each brush spring onto the post on the brush holder assembly just enough to hold the inside end of spring from turning.
1.2. Grasp the free end of the spring with needle nose pliers and twist it to the right over the top of the brush socket.
1.3. Push the spring fully onto the post then release the free end to engage the notch in the brush socket.

NOTICE: Brush leads may be damaged by excessive handling. Do not overflex the leads near the clip welds or the clips may break

Frame And Field Assembly:

2. Install the brushes, if they were removed.
2.1. Ensure that the insulated brushes go into the brush sockets of the brush holder assembly that mounts on the insulation.
2.2. To install each brush, grasp the free end of the brush spring with needle nose pliers, twist it to the right to clear the brush socket, then insert the brush partly into the brush socket.
2.3. Gradually release the springs so that its end contacts the side (not end) of the brush. This will hold the brushes retracted until after the brush holder is installed over the armature commutator.
3. Install the grounded brush screws.
3.1. Position the terminals of the grounded brush leads behind the terminal tabs on the brush holder.
3.2. Insert the brush screws through the terminal tabs on the brush holder and thread them into the brush lead terminals.
