9. Measure the commutator (A) runout.
-
If the commutator runout is within the service limit, check the commutator for carbon dust or brass chips between the segments.
-
If the commutator runout is not within the service limit, replace the armature.
10. Check the mica depth (A). If the mica is too high (B), undercut the mica with a hacksaw blade to the proper depth. Cut away all the mica (C)
between the commutator segments. The undercut should not be too shallow, too narrow, or V-shaped (D).
11. Use an ohmmeter to check for continuity between the segments of the commutator. If there is an open circuit between any segments, replace the
armature.
