Starter Drive Pinion Depth Adjustment

 

After the starter motor (11001) has been assembled, the pinion gap must be checked.

  1. Mount the starter motor securely in a vise.

  1. Using two switches and a battery, connect the starter motor as shown.

  1. When switches K1 and K2 are closed, the starter drive (11350) will be forced outward and the starter motor will turn. By opening switch K2, the starter motor will stop turning with the pinion in the full out position.

  1. Gently push the pinion back by hand and measure the amount of pinion movement. The amount corresponds to the pinion gap of conventional starters. End gap should be 0.1-2.0mm (0.004-0.079 inch).

  1. Adjust the end gap by changing the shims between the solenoid and the drive end housing. Increasing the shims will decrease the gap. Decreasing the shims will increase the gap.
