6. 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).
Commutator mica depth
Standard (New) : 0.5 mm (0.0197 in.)
Limit : 0.2 mm (0.0079 in.)
7. Check for continuity between the segments of the commutator. If an open circuit exists between any segments, replace the armature.
8. Check with an ohmmeter that no continuity exists between the commutator (A) and armature coil core (B), and between the commutator and
armature shaft (C). If continuity exists, replace the armature.
