Preparations for the initial and each additional star-
ting operation should include careful checks of the
oil, fuel, cooling, and electrical systems. The cylinder
air housing door should be closed with all airshrouds
in
place.
Before engine is put in operation, check all com-
ponents for mechanical security. If an abnormal
condition, defective part, or operating difficulty is
detected, repair or service as required. The engine
should be kept free of dust,
dirt,
and spilledoil or fuel.
Be sure proper operating procedure is followed.
Crankcase
Oil:
Use an oil with the API designation
CD/SD or CD/SE. However, to reduce oil consump-
tion to a normal level in theshortest time possible on a
new or rebuilt engine, use CC oil for the first fill only
(50
hours). Then use the recommended oil only.
Select the correct SAE grade oil by referring to the
following:
Above
32"
F
(0"
C)
.......................
SAE
30
0"
F
to
32" F
(-18" C to 0°C)
...
SAE 1OW or
5W-30
Below
0"
F
(-18"
C)
..................
SAE
5W-30
Multigrade oils are recommended for temperatures of
32"
F
(0"
C) and below, but they are not recommend-
ed for temperatures above
32"
F
(0"
C). When adding
oil between oil changes,
it
is preferable to use the
same brand as various brands of oil may not be
compatible when mixed together.
Never remove
011
level Indicator cap with the
engine running, because oil will blow out of
the tube causing possible injury.
Recommended Fuel:
Although number
2
diesel fuel
gives the best economy for most operating con-
ditions, number
1
diesel fuel can be used:
1.
When ambient temperatures are below
32°F
2.
During long periods of light engine load;
or,
3.
If preferred by user.
(0"
C);
Use low sulfur content fuel having a pour point (ability
to filter) of at least 10" below the lowest expected
temperature. Keep the fuel clean and protected from
adverse weather. Leave some room for expansion
when filling the fuel tank.
Due to the precise tolerances of diesel injec-
tion systems, it is extremely important the fuel
be kept clean. Dirt in the system can cause severe damage to both
the injection pump and the injection nozzles.
Bleed air from fuel system as follows: Disconnect the
fuel return line. See Figure 1
.
Operate the hand
priming lever on diaphragm type fuel transfer pump
until there are no air bubbles in fuel flowing from the
fuel return line fitting. Then connect the fuel return
line.

If
the camshaft pump lobe is up, crank engine one revolution to
permit hand priming. When finished, return priming lever inward
(disengaged position) to permit normal pump operation.
