Pinion Clearance
The pinion clearance cannot be adjusted but should be
checked after reassembly of the motor to insure proper
clearance. Improper clearance is an indication of worn parts.
To check pinion clearance, follow the steps listed below:
1. Disconnect the motor field coil connector from the
solenoid motor terminal and INSULATE IT CAREFULLY.

2. Connect a battery from the solenoid switch terminal
to the solenoid frame (Fig. 6D-57).
3. MOMENTARILY flash a jumper lead from the
solenoid motor terminal to the solenoid frame. This will shift
the pinion into cranking position and it will remain so until
the battery is disconnected.
