Drive Pinion
Remove the stopper for the overrunning clutch by us-
ing a pipe as shown in the figure.
Adjustment of Pinion Gap
1. Disconnect the wiring from terminal (M).
2. Apply battery power to the terminal (S) and ground
the starter motor body, the pinion will eject outward
and then stop.
3. Measure the clearance (pinion gap) between the
pinion and the stopper.
Pinion gap: 0.5—2.0 mm (0.020—0.079 in)
Caution
Do not let electricity flow continuously for
more than 10 seconds.
If the pinion gap is not within the specified range,
make the adjustment by increasing or decreasing
the number of washers used between the magnetic
switch and the drive housing. The gap will become
smaller if the number of washers is increased.
Caution
Do not use the washers
(0.079 in) in all.
more than 2 mm
INSPECTION
Armature Coil
1. Ground of the armature coil
(1) Check for continuity between the commutator
and the core by using a circuit tester.
(2) Replace the armature if there is continuity.

3. Switch coil
(1) Check for continuity between the M terminal
and the body by using a circuit tester.
(2) Replace the switch if there is no continuity.
PERFORMANCE INSPECTION
Magnetic Switch
Disconnect the terminal M wire, and make the fol-
lowing tests.
Pull-in Test
The switch is normal
if
the pinion ejects outward when
the battery is connected as shown in the figure.
Caution
Do not supply power continuously for more
than 10 seconds.
Hold-in Test
1. After completing the pull-in test, disconnect the wire
from terminal M (with the pinion left ejected).
2. The hold-in coil is functioning properly if the pin-
ion does not return.

Return Test
1. Connect the battery between terminal M of the
magnetic switch and the body, as shown in the
figure.
2. Pull the pinion out manually to the pinion stopper
position.
3. The pinion should immediately return to its origi-
nal position when it is released.
No-load Test
1. After adjusting the pinion gap, form a test circuit
with a voltmeter and an ammeter.
Note
Use wires as thick as possible and tighten
each terminal fully.
2. Close switch "K" to run the starter.
3. If the voltmeter and ammeter show the following
values while the starter is running, it is normal.

ON-VEHICLE INSPECTION
Charge the battery fully before starting the following
inspection.
1. Turn the ignition switch to the start positron.
2. Check that the starter motor operates.
3. If the starter does not operate, check the voltage
between S terminal and ground using a voltmeter.
4. If the voltage is 8V or more, the starter is mal-
function.
5. If less than 8V, the wiring harness is malfunction.
Caution
If the magnetic switch is hot, it may not func-
tion even though the voltage is standard volt-
age or more.
Note
The cranking speed is greatly affected by the
viscosity of the engine oil.

align the through bolts.
CHECKING OPERATION
Magnetic Switch
Make the following tests:
Pull-out test
1. Check that the pinion is pulled out when 12V is con-
nected to the S terminal and the body is grounded.
2. Measure the pinion gap while the pinion is pulled
out.
Specification: 0.5—2.0 mm (0.02—0.08 in)
3. Adjust the pinion gap with an adjust washer (drive
housing front cover—magnetic switch) if it is not
within specification.
Return test
1. Disconnect the motor wire from the M terminal, and
then connect the battery power to the M terminal
and ground the body.
2. Pull out the overrunning clutch with a flat-tip screw-
driver. Check that the overrunning clutch returns
to its original position when released.

inspections.
A.If the magnetic switch dose not function dur-
ing starting.
1. Turn the ignition switch to the start position.
2. Measure the voltage between the S terminal and

there is starter malfunction.
4. If it is less than standard voltage, there is a mal-
function in the wiring.
Standard voltage: 8 V

tion even though the voltage is standard volt-
age or more.
B.lf the starter won't crank, or if the cranking
speed is slow.
The problem may be a malfunction of the starter
or in the wiring.
