1. Visually inspect the commutator sur-

polish it with 600-grit wet-or-dry sand-
paper.
2. Measure the outside diameter of the
commutator by use of a vernier caliper.
If the diameter is less than the specified
minimum outside diameter, replace the
whole armature.

Standard: 22 mm (0.87 in)
Minimum: 21 mm (0.83 in)
