Commutator and Mica

1. Check the contact of the commutator for wear, and grind the

commutator with emery paper if it is slightly worn.

2. Measure the commutator O.D. with an outside micrometer at

several points.

3. If the minimum O.D. is less than the allowable limit, replace the

armature.

4. If the difference of the O.D.'s exceeds the allowable limit, correct

the commutator on a lathe to the factory specification.

5. Measure the mica undercut.

6. If the undercut is less than the allowable limit, correct it with a saw

blade and chamfer the segment edges.
