CAUTION
• Never use emery cloth on the commutator. Particles of emery are conductive and may short-
circuit the commutator bars. Never use oil or lubricants on the commutator or brushes.
2. Using a micrometer, measure the outside diameter at four points; two points 90° to each other to the out-
side of the commutator (A1 and A2), and two points 90° to each other to the inside of the commutator
(B1 and B2). If the commutator diameter is less than 1.535 inches (39 mm) at any of the four locations,
replace the armature assembly and bearings (Figure 12a-12, Page 12a-9).
Measure each position
in 2 places, 90° apart.

CAUTION
• Do not submerge armature in solvent.
NOTE: Before testing, wipe the armature with a clean cloth and remove carbon dust and metal particles
from between commutator bars.
1. Using a multimeter set on 200 Ω (ohms), place the positive probe on the commutator bars and the neg-
ative probe on the armature core. The reading should be no continuity. If the reading is incorrect, replace
the armature and the two bearings (Figure 12a-13, Page 12a-10).
