6. Reconnect field coil leads to solenoid terminal.
PINION CLEARANCE CHECK
There is no provision for adjusting pinion clear­
ance on the enclosed shift lever cranking motor.
When the shift lever mechanism is correctly as­
sembled, the pinion clearance should fall within the
specified limits (.010"-.140"). When clearance ex­
ceeds these limits it may indicate excessive wear of
solenoid linkage or shift lever yoke buttons.
Pinion clearance should be checked after motor
has been disassembled and reassembled.
Check pinion clearance in following manner:
1. Disconnect the motor field coil connector from
the solenoid motor terminal and insulate it carefully.
2. Connect one battery lead to the solenoid switch
terminal and the other to the solenoid frame (Fig.
6E-9).
5. Measure the distance between pinion and pinion
stop (Fig. 6E-10).

3. Flash a jumper lead momentarily 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 pinion back towards the commutator end
to eliminate slack movement.

INSTALL IN CAR—6-CYL. ENGINE
1. Install starting motor.
NOTE: Make sure that the shim has been in­
stalled if this car is equipped with an automatic
transmission.
2. Connect battery positive cable and wiring har­
ness leads to starting motor solenoid.
3. Connect battery ground cable at battery ter­
minal post.
INSTALL IN CAR-V-8 ENGINE
1. Connect battery cable and solenoid wires to
solenoid.
NOTE: Connect purple (or violet) wire to ter­
minal marked S.
2. Install starting motor on engine and tighten
mounting screws securely.
NOTE: Make sure that the shims have been in­
stalled if this car is equipped with an automatic
transmission.
3. Push cables up where they can be reached from
above car, then lower car.
