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
SURFACES
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 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.
5. INSPECT COMMUTATOR DIAMETER
Using vernier calipers, measure the commutator diameter. Standard diameter:
1.4 kW type: 30 mm (1.18 in.)
2.0 kW type: 35 mm (1.38 in.)
Minimum diameter:
1.4 kW type: 29 mm (1.14 in.)
2.0 KW type: 34 mm (1.34 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:
1.4 kW type: 0.6 mm (0.024 in.)
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 FIELD COIL FOR GROUND
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:
1.4 kW type:15.5 mm (0.610 in.)
2.0 kW type:15.0 mm (0.591 in.)
Minimum length:
1.4 kW type: 10.0 mm (0.394in.)
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 spring installed load:
1.4 kW type:
17.6 − 23.5 N (1.79 − 2.41 kgf, 4.0 − 5.3 lbf)
2.0 kW type:
21.5 − 27.5 N (2.19 − 2.80 kgf, 4.8 − 6.2 lbf)
