WARNING
When performing electrical maintenance,
ALWAYS disconnect intervehicular electrical
cable from semitrailer, and negative battery
cables at batteries. Failure to follow this
warning may create a spark and explosion,
resulting in serious injury or death to
personnel.
(1) Remove negative battery cable from battery
(fig. 4-37).
(2) Starter removal is done from underneath the
vehicle on the left side of the engine.
(3) Remove starter solenoid protective bracket
(1) by removing two retaining capscrews (2) and washers
(3). Remove five capscrews (4) from engine air shutter.
After these screws are removed, the engine air shutter can
be raised to get at top retaining bolt on starter.
(4) Remove hot lead No. 6 from large bottom
pole of solenoid and lead No. 74 from small pole on rear
side of solenoid.
(5) Remove capscrew (5), washer (6), capscrew
(7), external tooth lockwasher (8), and nut (9) from starter
rear support bracket (10). Remove rear starter bracket.
(6) Raise engine shutter (fig. 4-124) so you can

Installation.
WARNING
When performing electrical maintenance,
ALWAYS disconnect intervehicular electrical
cable on semitrailer, and negative battery
cables at batteries. Failure to follow this
warning may create a spark and explosion,
resulting in serious injury or death to
personnel.
(1) Before installing starter motor, check the
pinion clearance (fig. 4-124). Proper clearance is
important to ensure that starter engages.
(a)
Press on solenoid core to shift the pinion
into full mesh position, then measure the clearance
between the pinion and pinion stop.
