Commutator and Mica
1. Check the contact face of the commutator for wear, and grind the
commutator with emery paper
if it is slightly worn.
2. Measure the commutator 0.0. with an outside micrometer at
several
pOints.
3. If the minimum 0.0. is less than the allowable limit, replace the
armature.
4. If the difference of the O.O.'s exceeds the allowable limit, correct
the commutator
on a lathe to the factory speCification.
5. Measure the mica undercut.
6. Ifthe undercut is less than the allowable limit, correct it with a saw
blade and chamfer the segment edges.
