5. If pinion gap is out of specification, adjust by adding or
removing gaskets between magnetic switch and front
bracket.
MAGNETIC SWITCH PULL-IN TEST
1. Disconnect field coil wire from M-terminal of magnetic
switch.
2. Connect a 12 V battery between S-terminal and
M-terminal.
Caution
This test must be performed quickly (in less than
10 seconds) to prevent coil from burning.
3. If pinion moves out, then pull-in coil is good. If it doesn’t,
replace magnetic switch.
MAGNETIC SWITCH HOLD-IN TEST
1. Disconnect field coil wire from M-terminal of magnetic
switch.
2. Connect a 12 V battery between S-terminal and body.
Caution
This test must be performed quickly (in less than 10
seconds) to prevent coil from burning.
3. Manually pull out the pinion as far as the pinion stopper
position.
4. If pinion remains out, everything is in order. If pinion moves
in, hold-in circuit is open. Replace magnetic switch.
FREE RUNNING TEST
1. Place starter motor in a vise equipped with soft jaws
and connect a fully-charged 12 V battery to starter motor
as follows:
2. Connect a test ammeter (100-ampere scale) and carbon
pile rheostat in series with battery positive post and starter
motor terminal.
3. Connect a voltmeter (15 V scale) across starter motor.
4. Rotate carbon pile to full-resistance position.
5. Connect battery cable from battery negative post to starter
motor body.
6. Adjust the rheostat until the battery voltage shown by
the voltmeter is 11 V Reduction.
7. Confirm that the maximum amperage is within the
specifications and that the starter motor turns smoothly
and freely.

MAGNETIC SWITCH RETURN TEST
1. Disconnect field coil wire from M-terminal of magnetic
switch.
2. Connect a 12 V battery between M-terminal and body.
Caution
This test must be performed quickly (in less than
10 seconds) to prevent coil from burning.
3. Pull pinion out and release. If pinion quickly returns to
its original position, everything is in order. If it doesn’t,
replace magnetic switch.
Caution
Be careful not to get your fingers caught when pulling
out the pinion.

DISASSEMBLY SERVICE POINTS
A
A" MAGNETIC SWITCH REMOVAL
Disconnect field coil wire from “M” terminal of magnetic switch.
A
B" ARMATURE/BALL REMOVAL
Caution
When removing the armature, take care not to lose the
ball (which is used as a bearing) in the armature end.
A
C"SNAP RING/STOP RING REMOVAL
1. Press stop ring off snap ring with a suitable socket.
2. Remove snap ring with snap ring pliers and then remove
stop ring and overrunning clutch.
STARTER MOTOR PARTS CLEANING
1. Do not immerse parts in cleaning solvent. Immersing the
yoke and field coil assembly and/or armature will damage
insulation. Wipe motor assembly with a cloth only.
2. Do not immerse drive unit in cleaning solvent. Overrunning
clutch is pre-lubricated at the factory and solvent will wash
lubrication from clutch
3. The drive unit may be cleaned with a brush moistened
with cleaning solvent and wiped dry with a cloth.
