To check pinion clearance, perform the following steps.
1. Disconnect the motor field connector from the solenoid "M" terminal and Insulate It carefully.
2. Connect a battery of the same voltage as the solenoid from the solenoid switch terminal to the solenoid frame.
Pinion Clearance Check
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.
4. Push the pinion back toward the commutator end to eliminate stack movement.
Measuring Pinion Clearance
