CAUTION
Avoid getting petroleum products, such as dry
rubber parts, as they will deteriorate the rubber.
a. General. Any special cleaning instructions required for speci-
fic components or parts are contained in the pertinent section.
General cleaning instructions are as outlined in (1) through (4)
below.
(1) Metal parts.
(a) Use clean water or a solution of 1/4 pound of soap chips
to 1 gallon of hot water for all parts and for overall general clean-
ing of painted surfaces.
(b) After parts are clean, dry them thoroughly. Apply a light
film of lubricating oil preservative, medium (MIL-L-3150) to all parts
having a polished surface to prevent rusting.
(c) Before installing new parts, remove any rust-preventing
compound, protective grease, etc. Prepare as required (oil seals,
etc.). For those parts requiring lubrication, apply the lubricant
(2) Electrical parts.
Use technical trichloroethane (methyl
chloroform), specification O-T-620, for cleaning. Clean painted parts:
and plastics by wiping, brushing, or spraying but never immersing or
soaking in trichloroethane. Do not use trichloroethane to clean
leather or rubber parts (other than neoprene).
(3) Rubber parts other than electrical. Clean rubber parts with
soap and warm water. Apply a coating of powdered talcum (specifica-
tion U-T-30) to preserve the rubber.
(4) Meters. Clean each meter glass using a soft cloth dampened
with a solution of common detergent and water. After cleaning, allow
to dry without rubbing.
b. Rust Removal. Remove rust or corrosion from all parts of the
test stand. To remove rust or corrosion from unfinished surfaces, use
steel cleaning brushes or abrasive cloth. On finished surfaces other
than highly polished surfaces, remove rust or corrosion by buffing
with a rotary wire brush constructed of steel wire between 0.010 and
0.025 inch in diameter. Crocus cloth may be used manually to remove
rust or corrosion from polished surfaces.
c. Paint Touch-up. To touch up painted enclosure surfaces, use
primer, specification TT-P-664, followed by enamel paint, alkyd gloss,
specification TT-E-489, class B, machinery gray color per ANSI 255.1,
color chip number 70.
