Installation of Brush Holder
Install the brush holder assembly and rear cover and
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.

No-Load Test
1. After adjusting the pinion gap, form a test circuit
with a voltmeter and an ammeter.
Note
Use heavy gauge wires and tighten each ter-
minal fully.
2. Close switch K to run the starter.
3. Check for the following:
Voltage (V) 11.0
Current (A) 90 max.
Gear shaft speed (rpm) 3,000 min.
4. If any abnormality is noted, check for the cause
according to "Inspection".
INSTALLATION
Install in the reverse order of removal.
Note
When installing the starter, tighten the bolts
to the specified torque.
Tightening torque:
Bolts 37—52 N m
(3.8—5.3 m-kg, 27—38 ft-lb)
B terminal 9.8—11.8 N-m

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.

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.
