Checking Pinion Clearance
Pinion clearance must be checked as follows after reassembly of motor to insure proper
adjustment.
1. Disconnect motor field coil connector from solenoid motor terminal and insulate it care-
fully.
2. Connect 12 volt battery positive (+) lead to solenoid switch and negative (–) lead to sole-
noid frame.
3. Momentarily touch a jumper lead from solenoid motor terminal M to starter motor frame.
This shifts pinion into cranking position where it will remain until battery is disconnected.
4. Push pinion back toward commutator end to eliminate slack.
5. Measure distance between pinion and pinion retainer.
