3.3.14 Diesel Engine Processing.
3.3.14.1 Fuel System and Combustion Chamber. Prior to processing engine,
the engine shall be cooled to assure that cylinder head temperature, measured
at injector nozzle flange surface of all cylinders, is not more than 100F.
Cooling shall be accomplished by induced air currents, circulation of engine
coolant, or by waiting the period of time required to arrive at the above
specified temperature. When ambient temperature exceeds 100F, engine shall
be cooled to a temperature equivalent to ambient. After engine has been
cooled, the fuel supply system from the fuel tank shall be shut off. A
portable container with two compartments shall be positioned to provide
gravity feed to the engine. One compartment shall be filled with preservative
oil conforming to grade 1 of MIL-P-46002 to which has been added an oil
soluble red dye conforming to MIL-D-81298, in a concentration sufficient to
impart a marked coloring to the oil. The second compartment shall be filled
with diesel fuel conforming to VVF-800 (see note 1). The fuel line between
the primary fuel filter and fuel pump at the primary fuel filter outlet shall
be disconnected. The residual diesel fuel from the secondary fuel filter
shall be drained. (Note: If vehicle is not equipped with a secondary fuel
filter, disregard all requirements concerning the secondary fuel filter.) The
filter can shall be removed and the filter element extracted. The filter can
shall be filled with oil, preservative, grade 1, MIL-P-46002 and replaced.
The residual dispenser fuel return line shall be disconnected at quick
disconnect coupling. A transparent plastic fuel line shall be connected to
the engine end of the disconnected fuel return line and the other end of the
plastic fuel line inserted into a recovery container to collect the residual
returned oil. An air restrictor plate fabricated in accordance with Figure 4
shall be installed at the nearest and most convenient place to cut off the air
supply to the engine; assuring that air leakage to the engine is completely
sealed off. The fuel line on the auxiliary fuel tank shall be turned to the
preservative oil position (grade 1, MIL-P-46002). The throttle shall be
placed at the maximum open position and engine cranked with starter for a
minimum period of 30 seconds, not exceeding a maximum of 45 seconds. (Note:
Engine may fire for approximately five (5) seconds. If engine continues to
fire, stop cranking and rock starter intermittently to prevent engine from
running.) The fuel valve on the auxiliary fuel container shall be turned to
the off position. The filter can shall be removed from the secondary fuel
filter, The oil, preservative, grade I, HIL-P-46002, shall be drained and the
l
can, wiped clean with a clean lint free cloth. The element shall be
reinstalled, the can filled with diesel fuel, VV-F-800, and the filter can
reinstalled.
NOTE 1 - The container shown in Figure 3 has proven
satisfactory for engine preservation.
CAUTION:
Special precautions shall be taken to assure
that time limits specified shall not be
exceeded or the engine, starter or starter
solenoid may be damaged.
