Inspect Armature Commutator
The armature commutator shown in Fig. 16 (A) can
be cleaned with fine sandpaper. DO NOT use emery
cloth. The commutator can be machined a diameter
of NO LESS THAN
1.230” (31.24 mm) .
Slots between commutator bars should be cleaned
as shown in
Fig. 16 (A) after sanding or machining.
Check the armature for shorts with a growler.
NOTE: The style armature commutator shown in
Fig. 16 (B) cannot be machined.

Inspect Brushes
Check the brushes for proper seating, weak brush
springs, dirt, oil or corrosion. Brush springs should
be strong enough to ensure good brush contact with
armature. Replace the brushes if worn to
1/4” (6
mm) (1) or less Fig. 17 (A) , or 1/8” (3 mm) (2) or
less, Fig. 17 (B) . Lengths of new brushes (3) are
shown for reference.
Verify that the brushes are not sticking in their
holders.
