FREE RUNNING TEST
1. Place the starter motor in a vise equipped with soft jaws and
connect a fully-charged 12-volt battery to the starter motor
as follows:
2. Connect a test ammeter (100-ampere scale) and carbon pile
rheostat in series between the positive battery terminal and
starter motor terminal.
3. Connect a voltmeter (15-volt scale) across the starter motor.
4. Rotate carbon pile to full-resistance position.
5. Connect the battery cable from the negative battery terminal
to the starter motor body.
6. Adjust the rheostat until the battery positive voltage shown
by the voltmeter is 11 V.
7. Confirm that the maximum amperage is within the
specifications and that the starter motor turns smoothly and
freely.
Current: maximum 90 Amps
.
MAGNETIC SWITCH RETURN TEST
1. Disconnect the field coil wire from the M-terminal of the
magnetic switch.
CAUTION
This test must be performed quickly (in less than 10 sec-
onds) to prevent the coil from burning.
2. Connect a 12-volt battery between the M-terminal and body.
WARNING
Be careful not to get your fingers caught when pulling
out the pinion.
3. Pull the pinion out and release. If the pinion quickly returns
to its original position, everything is operating properly. If it
doesn't, replace the magnetic switch.

DISASSEMBLY SERVICE POINTS
.
<<A>> ARMATURE AND BALL REMOVAL
CAUTION
When removing the armature, take care not to lose the ball
(which is used as a bearing) in the armature end.
.
<<B>> SNAP RING AND STOP RING REMOVAL
1. Press a long socket wrench of appropriate size to the stop
ring. Then tap the socket wrench to remove the stop ring to
the pinion gear side.
2. After removing the snap ring (by using snap-ring pliers),
remove the stop ring and the overrunning clutch.
STARTER MOTOR PART CLEANING
1. Do not immerse parts in cleaning solvent. Immersing the
yoke and field coil assembly and/or armature will damage
insulation. Wipe these parts with a shop towel only.
2. Do not immerse the drive unit in cleaning solvent.
Overrunning clutch is pre-lubricated at the factory and
solvent will wash lubrication from the clutch.
3. The drive unit may be cleaned with a brush moistened with
cleaning solvent and wiped dry with a shop towel.

INSPECTION
M1162001300061
.
COMMUTATOR CHECK
1. Place the armature on a pair of V-blocks, and check the
deflection by using a dial gauge.
Standard value: 0.05 mm (0.002 inch)
Limit: 0.1 mm (0.004 inch)
2. Check the outer diameter of the commutator.
Standard value: 29.4 mm (1.16 inches)
Minimum limit: 28.8 mm (1.13 inches)
3. Check the depth of the undercut between segments.
Standard value: 0.5 mm (0.02 inch)
Minimum limit: 0.2 mm (0.008 inch)
.
BRUSH CHECK
1. Check the brush for roughness of the surface that contacts
the commutator and check the brush length.Replace the
brush holder if this measurement exceeds the limit.
Minimum limit: 7.0 mm (0.28 inch)
2. .In the case contacting surface has been corrected or the
brush has been replaced, correct the contacting surface by
winding sandpaper around the commutator
