Preliminary Starter Motor Disassembly
1. Scribe marks completely down 1 side of the starter motor in order to ensure proper alignment of all of the components during assembly. Use a
colored pencil or a marker that will show on all of the components.
2. Use the following procedure in order to remove the motor lead on the frame assembly from the solenoid assembly:
2.1. Remove the nut from the motor terminal.
2.2. Slip off the motor lead.
2.3. Reinstall the nut.
3. Remove 2 through-bolts.
4. Remove 2 brush plate screws.

IMPORTANT: Do not lose the small dowel pin that is installed between the frame assembly and the gear reduction and drive group. The dowel
pin is necessary for assembly. If the dowel pin is lost, replace the dowel pin with a 2 mm X 10 mm (0.79 in X 0.394 in) long pin. Obtain the new
pin or manufacture the pin locally.
