There is no provision for adjusting pinion clearance on this motor, but clearance should be checked after motor reassembly. When the shift lever is assembled properly, pinion clearance should be 0.010-0.060 inch.When clearance is not within specifications, it may indicate excessive wear of the solenoid linkage or the shift lever yoke buttons. Check pinion clearance as follows:

1. Disconnect motor field coil connector from solenoid motor terminal, then insulate end carefully.
2. Connect one battery lead to solenoid switch terminal, then the other lead to the solenoid frame.
3. Connect a jumper lead to solenoid motor terminal. Momentarily flash lead to solenoid frame. This will shift pinion into cranking position until the battery is disconnected.
4. Push pinion back toward commutator end as far as possible to take up any slack movement, then check clearance with a feeler gauge.
