1. ARMATURE
1) Check the commutator for any sign of burns of
rough surfaces or stepped wear. If wear is of a mi-
nor nature, correct it by using sand paper.
2) Run-out test
Check the commutator for run-out, and then re-
place if it exceeds the limit.
Commutator run-out:
Standard
0.05 mm (0.0020 in)
Service limit
Less than 0.10 mm (0.0039 in)
(A) Dial gauge
(B) V-block
3) Depth of segment mold
Check the depth of segment mold.

4) Armature short-circuit test
Check the armature for short-circuit by placing it on
growler tester. Hold an iron sheet against the arma-
ture core while slowly rotating the armature. A
short-circuited armature will cause the iron sheet to
vibrate and to be attracted to core. If the iron sheet
is attracted or vibrates, the armature, which is
short-circuited, must be replaced or repaired.

5) Armature ground test
Using a circuit tester, touch one probe to the com-
mutator segment and the other to shaft. There
should be no continuity. If there is continuity, the ar-
mature is grounded.
Replace the armature if it is grounded.
