PINION CLEARANCE CHECK INSTALL IN CAR
-
&CYL. ENGINE
There is no provision for adjusting pinion clearance on the
enclosed shift lever cranking motor. When the shift lever
mechanism is correctly assembled, the pinion clearance
should fall within the specified limits (.010"-.ON"). When
clearance exceeds these limits, it may indicate excessive
wear of solenoid linkage or shift lever yoke buttons.
1. Position starter motor to engine and attach with thru
bolts.
2. Swing starter motor brace into position and fasten
securely.
3. Connect battery positive cable and wiring harness
leads to starting motor solenoid.
4. Connect battery ground cable at battery terminal
post.
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.
INSTALL IN CAR

V-8 ENGINE
1 . Position starter motor on engine.
2. Connect battery cable and solenoid wires to solenoid
and fasten securely.
2. Connect one battery lead to the solenoid switch ter-
minal and the other to the solenoid frame (Fig. 6E-
15).
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.
NOTE: Connect purple (or violet) wire to ter-
minal marked 3 ' : yellow wire to terminal
marked " R ' !
3. Attach starting motor to engine thru bolts and fasten
4. Push pinion back towards the commutator end to
eliminate slack movement.
securely.
NOTE: Make sure that the shims have been
installed

transmission.
5. Measure the distance between pinion and pinion stop
(Fig. 6E- 16).
4. Swing brace into position and fasten securely.
