b. Using an ohmmeter, check that there is no continuity between the commutator and armature coil core.
If there is continuity, replace the armature.
c. Place the commutator on V-blocks. Using a dial gauge, measure the circle runout.
Maximum circle runout: 0.05 mm (0.0020 in.)
If the circle runout is greater than maximum, correct it on a lathe.
d. 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.
e. 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.
