ON-VEHICLE INSPECTION
Charge the battery fully before starting the following
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
ground.
3. If the measured value is standard voltage or more,
there is starter malfunction.
4. If it is less than standard voltage, there is a mal-
function in the wiring.
Standard voltage: 8 V
Caution
If the magnetic switch is hot, it may not func-
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.
Note
The cranking speed is greatly affected by the
viscosity of the engine oil.

REMOVAL AND INSTALLATION
1. Disconnect the negative battery cable.
2. Disconnect the wiring from the starter.
3. Raise the front of the vehicle and support it with
safety stands.
4. Remove the intake manifold bracket. (Fuel Injec-
tion Engine)
5. Remove the starter bolts.
6. Draw out the starter from lower side of the vehicle.
Installation in the revers order of removal.

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.

2. Vibration of the commutator
(1) Place the armature on V blocks, and measure
the vibration by using a dial gauge.
(2) If the vibration is Limit or more, repair so that
it becomes standard by using a lathe, or re-
place the armature.
Standard vibration: 0.05 mm (0.002 in)
Limit: 0.4 mm (0.018 in)
Note
Before checking, be sure that there is no play
in the bearings.
3. Outer diameter of the commutator
Replace the armature if the outer diameter of the
commutator is grind limit or less.
4. Roughness of the commutator surface
(1) If the commutator surface is dirty, wipe it with
a cloth.
(2) If it is rough, repair it by using a lathe or fine
sandpaper.
Grind limit: 31 mm (1.22 in)
5. Segment groove depth
If the depth of the mold between segments is limit
depth or less, undercut the grooves by standard
depth.
Standard depth:
0.5—0.8 mm (0.020—0.031 in)
Limit depth: 0.2 mm (0.008 in)
Field Coil
1. Wiring damage
(1) Check for continuity between the connector
and brushes by using a circuit tester.
(2) Replace the yoke assembly if there is no con-
tinuity.

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.
