INSPECTION
1. INSPECT COMMUTATOR FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
segments of the commutator.
If there is no continuity between any segment, replace the ar-
mature.
2. INSPECT COMMUTATOR FOR GROUND
Using an ohmmeter, check that there is no continuity between
the commutator and armature coil core.
If there is continuity, replace the armature.
3. INSPECT COMMUTATOR FOR DIRTY AND BURNT
SURFACE
If the surface is dirty or burnt, correct it with sandpaper (No.400)
or on a lathe.
4. INSPECT COMMUTATOR CIRCLE RUNOUT
(a) Place the commutator on V±blocks.
(b) Using a dial indicator, 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.
5. INSPECT COMMUTATOR DIAMETER
Using vernier calipers, measure the commutator diameter.
Standard diameter:
35.0 mm (1.378 in.)
Minimum diameter:
34.0 mm (1.339 in.)
If the diameter is less than minimum, replace the armature.
6. INSPECT UNDERCUT DEPTH
Check that the undercut depth is clean and free of foreign mate-
rials. Smooth out the edge.
Standard undercut depth:
0.7 mm (0.028 in.)
Minimum undercut depth:
0.2 mm (0.008 in.)
If the undercut depth is less than minimum, correct it with a
hacksaw blade.

7. INSPECT FIELD COIL FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
lead wire and field coil brush lead.
If there is no continuity, replace the field frame.
8. INSPECT SHUNT COIL FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
field coil end and field frame.
If there is no continuity, repair or replace the field frame.
9. INSPECT SHUNT COIL FOR OPEN CIRCUIT
Using an ohmmeter, measure the resistance between shunt
coil terminals (A) and (B).
Resistance: 1.5 to 1.9 W at 20 °C (68 °F)
If the resistance is not as specified, replace the field frame.
10. INSPECT BRUSH LENGTH
Using vernier calipers, measure the brush length.
Standard length: 15.0 mm (0.591 in. )
Minimum length: 9.0 mm (0.354 in. )
If the length is less than minimum, replace the brush holder and
field frame.
11. INSPECT BRUSH SPRING LOAD
Using a pull scale, measure the spring load by pulling the spring
from the brush until they are separated.
Standard spring installed load: 21.5 to 27.5 N ( 2.2 to
2.8 kgf, 4.8 to 6.2 lbf )
Minimum installed load: 12.7 N (1.3 kgf, 2.9 lbf )
If the installed load is less than minimum, replace the brush
springs.

12. INSPECT BRUSH HOLDER INSULATION
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.
13. INSPECT GEAR TEETH
Check the gear teeth on the pinion gear, idle gear and the clutch
assembly for wear or damage.
If any damage is found, replace the gear or clutch assembly,
and also check the drive plate ring gear for wear or damage.
14. INSPECT CLUTCH PINION GEAR
Rotate the pinion gear clockwise, and check that it turns freely.
Check that it locks by rotating the pinion gear counterclockwise.
If necessary, replace the clutch assembly.
15. INSPECT FRONT AND REAR BEARING
Turn the bearing by hand as applying inward force.
If resistance is felt or the bearing sticks, replace the bearing.
16. DO PULL±IN COIL OPEN CIRCUIT TEST
Using an ohmmeter, check that there is continuity between ter-
minals 50 and C.
If there is no continuity, replace the magnetic switch.
17. DO HOLDING COIL OPEN CIRCUIT TEST
Using an ohmmeter, check that there is continuity between ter-
minal 50 and the switch body.
If there is no continuity, replace the magnetic switch.

(g) Tighten terminal nuts.
(1) Put a wooden block on the contact plate and press
it down with a hand press.
Dimensions of wooden block:
20 x 33 x 40 mm (0.79 x 1.30 x 1.57 in.)
Press force:
981 N (100 kgf, 221 lbf)
NOTICE:

Check the diameter of the hand press ram. Then cal-
culate 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 (170 kgf´cm, 13 ft´lbf)
NOTICE:
If the nut is over tightened, it may cause cracks on the plas-
tic frame.
(h) Clean contact surfaces of the contact plate and the plung-
er.
Clean the contact surfaces of the remaining contact plate
and plunger with a dry shop rag.
(i) Reinstall the magnetic switch end cover.
Install the plunger, the new gasket and the end cover with
the 3 nuts.
Torque: 3.6 N´m (37 kgf´cm, 32 in.´lbf)
