5. INSPECT COMMUTATOR DIAMETER
Using vernier calipers, measure the commutator diameter.
Standard diameter:
30 mm (1.18 in.)
Minimum diameter:
29 mm (1.14 in.)
If the diameter is less than minimum, replace the armature.
6. INSPECT COMMUTATOR UNDERCUT DEPTH
Check that the undercut depth is clean and free of foreign materials. Smooth out the edge.
Standard undercut depth:
0.6 mm (0.024 in.)
Minimum undercut depth:
0.2 mm (0.008 in.)
If the undercut depth is less than minimum, correct it with a hacksaw blade.
7. INSPECT FIELD FRAME (FIELD COIL) FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the lead wire and field coil brush lead.
If there is no continuity, replace the field frame.
