INSPECTION AND REPAIR

Repair or replace necessary parts if extreme wear or
damage is found during inspection.

Armature

1) Measure the outer diameter of commutator, and

replace with a new one if it is out of the limit.

Standard: 38.0 mm (1.50 in)
Limit: 36.5 mm (1.44 in)

2) Check for continuity between commutator and

segments. Replace commutator if there is no
continuity (i.e., disconnected).

3) Check for continuity between commutator and

shaft. Also, check for continuity between
commutator and armature core, armature core and
shaft. Replace commutator if there is continuity
(i.e., internally grounded).

4) Measure runout of armature core and commutator

with a dial gage. Repair or replace, if it exceeds the
limit.

Armature

Standard: 0.05 mm (0.002 in) Max.
Limit: 0.1 mm (0.004 in)

Commutator

#500 to #600 if it is rough.

6) Measure the depth of insulator in commutator.

Repair, if it is below the limit.

Standard: 0.5 – 0.8 mm (0.02 – 0.03 in)

Limit: 0.2 mm (0.008 in)
