Starter Drive/Bendix: Testing and Inspection
PINION GAP
1. Measure the pinion gap while the pinion is pulled out as shown in the figure.
If the motor is running with the pinion forced endwise on the shaft, disconnect the connector from terminal M of switch assembly and connect terminal M to ground terminal (-) of battery with a lead wire. Next, gently push the pinion back with your fingertips and measure pinion gap.
2. If the pinion gap is outside specified range, remove or add number of adjustment washers used on the mounting surface of switch assembly until the correct pinion gap is obtained.
