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 no 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 table.
(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 a vernier caliper, measure the commutator diame-
ter.
Standard diameter: 30.0 mm (1.181 in.)
Minimum diameter: 29.0 mm (1.412 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.

6. INSPECT BRUSH HOLDER
Check the brush holder insulator. Using an ohmmeter, check
that there is no continuity between 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, idle gear and the
clutch assembly for wear or damage.
If damaged, replace the gear or clutch assembly.
If damaged, also check the drive plate ring gear for wear or
damage.
(b) Check the clutch pinion gear.
Rotate the pinion gear counterclockwise, 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 and while apply inward force.
If resistance is felt or bearing sticks, replace the bearing.

(f) Temporarily tighten the terminal nuts.
(g) Tighten the terminal nut
(1) Put a wooden block on the contact plate and press
it down with a hand press.
Dimensions of wooden block:
20 x 37 x 40 mm (0.79 x 1.46 x 1.57 in.)
Press force:
981 N (100 kgf, 221 lbf)
NOTICE:
Check the diameter of the hand press ram. Then
calculate the gauge pressure of the press when
981 N (100 kgf, 221 lbf) of force is applied.
Gauge pressure:
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, new gasket, end cover and lead
clamp with the 3 bolts.
Torque: 2.5 N´m (26 kgf´cm, 22 in.´lbf)

(a) Keep the vehicle level.
With the engine stopped, check the fluid level in the oil
reservoir.
If necessary, add fluid.

tem.
(See page SR-3)
(e) With the engine idling, measure the fluid level in the oil
reservoir.
(f) Stop the engine.
