CLEANING, INSPECTION, AND REPAIR (cont)
23. Clean, inspect, and repair armature assembly by the following:
Drycleaning solvent P-D-680 is toxic and flammable. Wear protective goggles and gloves and use
only in a well-ventilated area. Avoid contact with skin, eyes, and clothes and don't breathe vapors. Do
not use near open flame or excessive heat. The flash point is 100 - 138°F (38 - 59°C). If you become
dizzy, get fresh air immediately and get medical aid. If contact with eyes is made, wash your eyes and
get medical aid immediately.
Compressed air used for cleaning purposes will not exceed 30 psi (207 kPa). Do not direct
compressed air against skin. Use goggles or full face shield.
Check that drycleaning solvent does not get on commutator, copper parts, coils, and windings. Damage to
equipment will result.
Armature must be repaired at depot maintenance level.
Blow carbon dust from armature assembly with compressed air. Direct air into the pockets and through the
openings of the armature to remove internal accumulations of dirt.
Use a cloth dampened with drycleaning solvent and wipe armature surface to remove external grease and dirt.
Dry with compressed air.
Inspect for journal damage. If journal shows signs of bearing slippage, have armature repaired.
Do not coat commutator surfaces with insulating varnish.
If varnished surfaces of coil insulation are damaged, repair at depot level maintenance facility.
Inspect varnished surfaces of coil insulation.
