with preservative oil. The compressor should be run for five minutes, and
while it is operating, preservative oil should be sprayed into the intake with
the air cleaner removed until the oil coming from the unloader shows no sign
of emulsification. After compressors have been treated, they should be tagged
and dated.
Treat compressors to inhibit corrosion. The water jackets in the
engine block and in the radiator should be flushed out with a mixture
consisting of 60 percent antifreeze and 40 percent water. The water jackets
should then be drained, and openings not otherwise closed should be plugged
with suitable wood plugs and sealed with tape. Hydraulic couplings should be
refilled with oil. If a compressor is to stand idle for a long period, remove
the piston rod packing to avoid corrosion and pitting of the rods.
Engines

Diesel Engines. Diesel engines should be run for at least 5
a)
minutes, at a speed of not more than 15 percent above the
normal operating speed, under no load. Lubricating oil should
then be drained, and a yellow tag should be attached either to
the crankcase oil filler cap or in a conspicuous place on a
radial engine. This tag should read:
"CAUTION: This engine was treated for storage on (date) .
When the engine is placed in service, refill lubricating
oil sump with
."
Fuel lines and injectors should be drained and filled with
flushing oil. The exterior surfaces of the engines should be
cleaned of dirt and grease. All openings in engines and
accessories, including breathers, air intakes, exhausts,
exhaust expansion joints, and openings in starters and
generators, must be closed with plastic sheeting or waterproof
paper and taped. After all unprotected exterior surfaces of
engines are dry, all taped surfaces and all engine accessories,
except electrical wiring and accessories, should be sprayed
with a preservative compound.
b) Gasoline Engines. Gasoline engines should be run on unleaded,
undyed gasoline for at least 10 minutes beyond the time
required to run out the leaded gasoline in the lines and
carburetor. Interior surfaces of engines should be treated
with crankcase preservative oil as follows: remove spark
plugs; while the engine is rotating, spray sufficient oil
through spark plug holes for adequate protection to cylinder
walls, valve heads and stems, and valve guides using an air-
atomizing type of spray gun. For L-head type engines, the oil
may be poured in spark plug holes instead of spraying. Replace
