Periodic Maintenance
The starter motor requires no routine maintenance
beyond the occasional inspection of the electrical
connections which must be clean and tight, brush
wear and the commutator.
d. Installation
1.
Position the starter on the flywheel housing,
install three lock washers (6, Fig 10.9) and
three nuts (three bolts on later models), and
torque the nuts to 3.4 lb-ft (4,6 Nm) and the
bolts to 32 lb-ft (43 Nm).
2.
Connect all the wires to the starter solenoid
(5).
3.
Connect the positive (+) battery cable (2) to
the starter.
4.
Connect the positive (+) cable (2) to the
positive terminals on the batteries.
5.
Connect the negative (–) cable (1) to the
negative terminals on the batteries.
6.
Connect the ground cable (1) to the starter.

10.5.3 Starting Motor Relay
The starting motor relay, Fig. 10.10, consists of a
movable contact with a fixed coil in a weather-
proof casing.
The relay is internally grounded and is equipped
with two large terminals and one small terminal.
The two large terminals are for connection
between the batteries and the starting motor. The
small terminal is located on the lower side of the
relay.
Turning the ignition switch, with the transmission
in neutral, allows current to flow through the relay
coil via terminal to the ground point on the casing.
The flow of current energizes the coil forming a
magnetic field which attracts a movable contact.
When the contacts fully close, current from the
batteries is allowed to flow to the starting motor
through the relay.
Once the key switch is released, the flow of
current to the coil is stopped thereby breaking the
magnetic field and allowing the return spring to
open the contacts. This action stops the current
flow from the batteries to the starting motor.
