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.

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: 34 mm (1.34 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

if
the field coil is loose.
Brush and Brush Holder
1. Brush
If the brushes are worn beyond the wear limit, or
if the wear is near the limit, replace the brushes.

Wear limit: 11 mm (0.433 in)
2. Brush spring
(1) Measure the force of the brush spring by us-
ing a spring balance.

Bearing
Check for abnormal noise, looseness, insufficient
lubrication, etc. Replace the bearing if there is any
abnormality.
Take out the bearing, as shown in the figure, by us-
ing the suitable tools.
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.

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.
Note
Be careful not to let electricity flow continu-
ously for more than 10 seconds.
Pinion gap: 0.5—2.0 mm (0.020—0.079 in)
4. 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 more than plates.
