Starter Motor
Check Pinion Projection Length
1. Connect the positive (+) lead from a battery to
the “S” terminal.
2. Connect the negative (-) lead to the “M”
terminal.
3. Lightly pull the pinion away from the gear
housing.
4. Turn the switch ON and measure the pinion
moving distance L in the thrust direction
(Figure 10-35)
. Perform this test within 10
seconds.
Figure 10-35
See Starter Motor Specifications on page 10-5 for
service limit.
5. If the measured L dimension is outside the
standard range, adjust the dust covers to obtain
the standard range. Dust covers
(Figure 10-36, (1))
are available in 0.020 in.
(0.5 mm) and 0.031 in. (0.8 mm) thicknesses.

No-Load Test
Test the characteristics of the starter motor by
performing a no load test.
NOTICE
The starter motor can be damaged if operated
continuously longer than 10 seconds while
performing the no-load test.
1. Secure the starting motor in a vise or other
suitable fixture.
2. Connect an ammeter
(Figure 10-37, (1))
in
series between the battery positive (+) terminal
(Figure 10-37, (2))
and the main positive (+)
terminal
(Figure 10-37, (3))
on the starter
motor.
Note: The ammeter and all wire leads used in
this test must have a capacity equal to or
greater than the amperage draw
specification for the starter motor being
tested.

3. Connect a wire lead between the mounting
base of the starter motor
(Figure 10-37, (4))
and the battery negative terminal
(Figure 10-37, (5))
.
4. Connect a voltmeter
(Figure 10-37, (7))
to the
battery negative (-) terminal
(Figure 10-37, (5))
and the main positive (+) battery terminal
(Figure 10-37, (3))
on the starter motor.
