Cleaning and Inspection
1. The drive (71), armature (45) and fields (46)
should not be cleaned in any degreasing tank,
or with grease dissolving solvents, since these
would dissolve the lubricant in the drive and
damage the insulation in the armature and field
coils.
2. All parts except the drive should be cleaned
with mineral spirits and a clean cloth.
3. If the commutator is dirty, it may be cleaned
with No. 00 sandpaper.
NOTE: Never use emery cloth to clean commutator.
4. Inspect the brushes (13, Figure 2-6) for wear.
a. If worn excessively when compared with a
new brush, they should be replaced.
b. Make sure the brush holders (10) are clean
and the brushes are not binding in the hold-
ers.
c. The full brush surface should ride on the
commutator. Check by hand to insure that
the brush springs (16) are giving firm contact
between the brushes (13) and commutator.
d. If the springs (16) are distorted or discolored,
they should be replaced.
