Using an ohmmeter, check that there is continuity between
the segments of the commutator.
If there is no continuity, replace the armature.

Using an ohmmeter, check that there is no continuity
between the commutator and armature coil core.
If there is continuity, replace the armature.

Commutator

SURFACE
If the surface is dirty or burnt, correct with sandpaper
(No.400) or on a lathe.

Maximum circle runout: 0.05 mm (0.0020 in.)
If the circle runout is greater than maximum, correct it on a
lathe.
3. INSPECT COMMUTATOR DIAMETER
Using calipers, measure the diameter.
Standard diameter:
