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 GROUNDED
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
SURFACES
If the surface is dirty or burnt, clean 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:
1.2 kW, 1.4 kW type: 30 mm (1.18 in.)
1.8 kW, 2.0 kW type: 35 mm (1.38 in.)
Minimum diameter:
1.2 kW, 1.4 kW type: 29 mm (1.14 in.)
1.8 kW, 2.0 kW type: 34 mm (1.34 in.)
If the diameter is less than minimum, replace the armature.
6. INSPECT UNDERCUT DEPTH OF SEGMENT
Check that the undercut depth is clean and free of foreign mate-
rial. Smooth out the edge.
Standard undercut depth:
1.2 kW, 1.4 kW type: 0.6 mm (0.024 in.)
1.8 kW, 2.0 kW type: 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 THAT FIELD COIL IS NOT GROUNDED
Using an ohmmeter, check that there is no continuity between
the field coil end and field frame.
If there is continuity, repair or replace the field frame.
9. INSPECT BRUSH LENGTH
Using vernier calipers, measure the brush length.
Standard length:
1.2 kW, 1.4 kW type: 15.5 mm (0.610 in.)
1.8 kW, 2.0 kW type: 15.0 mm (0.591 in.)
Minimum length:
1.2 kW, 1.4 kW type: 10.0 mm (0.394 in.)
1.8 kW, 2.0 kW type: 9.0 mm (0.354 in.)
If the length is less than minimum, replace the brush holder and
field frame.
10. INSPECT BRUSH SPRING LOAD
Take the pull scale reading the instant the brush spring sepa-
rates from the brush.
Standard installed load:
1.2 kW type
13.7 − 19.6 N (1.40 − 2.00 kgf, 3.1 − 4.4 lbf)
1.4 kW type
17.6 − 23.5 N (1.80 − 2.40 kgf, 4.0 − 5.3 lbf)
1.8 kW, 2.0 kW type
21.5 − 27.5 N (2.20 − 2.80 kgf, 4.9 − 6.2 lbf)

1.8 kW, 2.0 kW type: 12.7 N (1.30 kgf, 2.7 lbf)
If the installed load is less than minimum, replace the brush
springs.
HINT:
Take the pull scale reading the instant the brush spring sepa-
rates from the brush.
11. INSPECT INSULATION OF BRUSH HOLDER
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.
12. INSPECT GEAR TEETH
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 flywheel or drive plate ring gear for
wear or damage.
13. INSPECT CLUTCH
Hold the starter clutch and rotate the clutch pinion gear clock-
wise and check that it turns freely. Try to rotate the clutch pinion
counterclockwise and check that it locks. If necessary, replace
the clutch assembly.
14. INSPECT REAR BEARING
Turn the bearing by hand while applying inward force.
If the resistance is felt or if the bearing sticks, replace the bear-
ing.
