INSPECTION
1. INSPECT ARMATURE COIL
(a) Check the commutator for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the segments of the commutator.
If there is no continuity between any segment, replace the ar-
mature.
(b) Check the commutator for ground.
Using an ohmmeter, check that there is no continuity be-
tween the commutator and armature coil core.
If there is continuity, replace the armature.
2. INSPECT COMMUTATOR
(a) Check the commutator for the dirty and burnt surfaces.
If the surface is dirty or burnt, correct it with sandpaper (No.400)
or on a lathe.
(b) Check for the commutator circle runout.
(1) Place the commutator on V±blocks.
(2) Using a dial gauge, measure the circle runout.
Maximum circle runout: 0.05 mm (0.0020 in.)
If the circle runout is greater than maximum, correct it on a lathe.
(c) Using vernier calipers, measure the commutator diame-
ter.
Standard diameter: 30.0 mm (1.181 in.)
Minimum diameter: 29.0 mm (1.142 in.)
If the diameter is less than minimum, replace the armature.
(d) Check that the undercut depth is clean and free of foreign
materials. Smooth out the edge.
Standard undercut depth: 0.6 mm (0.024 in.)
Minimum undercut depth: 0.2 mm (0.008 in.)
If the undercut depth is less than minimum, correct it with a
hacksaw blade.

3. INSPECT FIELD COIL
(a) Check the field coil for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the lead wire and field coil brush lead.
If there is no continuity, replace the field frame.
(b) Check the field coil for ground.
Using an ohmmeter, check that there is no continuity be-
tween the field coil end and field frame.
If there is continuity, repair or replace the field frame.
4. INSPECT BRUSHES
Using vernier calipers, measure the brush length.
Standard length: 15.5 mm (0.610 in.)
Minimum length: 10.0 mm (0.394 in.)
If the length is less than minimum, replace the brush holder and
field frame.
5. INSPECT BRUSH SPRINGS
Check the brush spring load.
Take the pull scale reading the instant the brush spring
separates from the brush.
Standard spring installed load:
1.2 kW13.7 ± 19.6 N (1.4 ± 2.0 kgf, 3.0 ± 4.4 lbf)
1.4 kW17.6 ± 23.5 N (1.8 ± 2.4 kgf, 3.9 ± 5.3 lbf)
Minimum spring installed load:
1.2 kW9.8 N (1.0 kgf, 2.2 lbf)
1.4 kW11.8 N (1.2 kgf, 2.6 lbf)
If the installed load is less than minimum, replace the brush
springs.

6. INSPECT BRUSH HOLDER
Check the brush holder insulation.
Using an ohmmeter, check that there is no continuity be-
tween the positive (+) and negative (±) brush holders.
If there is continuity, repair or replace the brush holder.
7. INSPECT CLUTCH AND GEAR
(a) Check the gear teeth on the pinion gear, idler gear and
clutch assembly for wear or damage.
If damaged, replace the gear or clutch assembly.
If damaged, also check the ring gear of the flywheel/drive plate
for wear or damage.
(b) Check the clutch pinion gear.
Hold the starter clutch and rotate the pinion gear counter-
clockwise, and check that it turns freely. Try to rotate the
pinion gear clockwise and check that it locks.
If necessary, replace the clutch assembly.
8. INSPECT MAGNETIC SWITCH
(a) Check the pull±in coil for open circuit.
Using an ohmmeter, check that there is continuity be-
tween terminals 50 and C.
If there is no continuity, check and replace the magnetic switch.
(b) Check the hold±in coil for open circuit.
Using an ohmmeter, check that there is continuity be-
tween terminal 50 and the switch body.
If there is no continuity, replace the magnetic switch.
9. INSPECT BEARING
Turn the bearing by hand while applying inward force.
If resistance is felt or the bearing sticks, replace the bearing.

If the contact plate is not pressed down with the spe-
cified pressure, the contact plate may tilt due to coil
deformation or the tightening of the nut.
(2) Using SST, tighten the nuts to the specified torque.
SST 09810±38140
Torque: 17 N´m (173 kgf´cm, 13 ft´lbf)
NOTICE:
If the nut is over tightened, it may cause cracks on the in-
side of the insulator.
(h) Clean the contact surfaces of the remaining contact plate
and plunger with a dry shop rag.
(i) Reinstall the plunger, a new gasket and the end cover
with the 3 bolts.
Torque: 2.5 N´m (26 kgf´cm, 23 in.´lbf)

TEST
NOTICE:
These tests must be done within 3 to 5 seconds to avoid
burning out the coil.
1. DO PULL±IN TEST
(a) Disconnect the field coil lead wire from terminal C.
(b) Connect the battery to the magnetic switch as shown.
Check that the clutch pinion gear moves outward.
2. DO HOLD±IN TEST
With battery connected as above with the clutch pinion gear
out, disconnect the negative (±) lead from terminal C. Check
that the pinion gear remains out.
3. INSPECT CLUTCH PINION GEAR RETURN
Disconnect the negative (±) lead from the switch body.
Check that the clutch pinion gear returns inward.
4. DO NO±LOAD PERFORMANCE TEST
(a) Connect the battery and ammeter to the starter as shown.
(b) Check that the starter rotates smoothly and steadily with
the pinion gear moving out. Check that the ammeter
shows the specified current.
Specified current: 90 A or less at 11.5 V
