6-18. FUEL INJECTOR INSTALLATION.
Ensure that the fuel injector bore in the cylinder head is dean. If necessary, dean carbon soot from the bore
using a dean rag placed on the end of a wooden dowel.
Lubricate the fuel injector bore in the cylinder head with dean lubricating oil, such as MIL-L-9000, or equivalent.
Lubricate the preformed packings (5, 6, and 7, Figure 6-21) with dean lubricating oil, such as MIL-L-9000, or
equivalent, and install them into the grooves on the adapter (17). Ensure that the preformed padrings (5, 6, and
7) are not twisted in the grooves after installation.
If the fuel injector will not seat properly in the bore in the cylinder head, remove the fuel
injector and inspect the preformed packings (5, 6, and 7) and the sealing ring (1) for signs of
twisting or damage. Straighten or replace as necessary.
Install the sealing ring (1) on the cup (16), and place the fuel injector into the bore in the cylinder head. Seat the
fuel injector in the bore in the cylinder head with a quick, hard push.
Place the damp (18) over the fuel injector and finger-tighten the capscrews (19).
Install the injector plunger link (2) in the plunger (3).
Torque the capscrews (19) alternately and evenly to 120 to 165 pound-inches (15 to 18 newton-meters).
Install the push rods (1 and 2, Figure 9-13), if removed, and install the valve crossheads (8, Figure 9-1), rock
arms (12, 13, and 14, Figure 9-2) and shaft (11) assembly, and the rocker arm cover (6, Figure 9-2) on the
cylinder head in accordance with paragraph 9-10.
SECTION V. FUEL TANK
6-19. GENERAL The fuel tank is of welded construction, and has a capacity of 130 gallons (492 liters). Three internal
baffles are welded in place to prevent fuel sloshing. Welded flanges are provided for the vent hose fittings, drain valve
nipple, fuel suction tube, fuel return hose elbow, liquid quantity transmitter, fuel level switch, and fuel level alarm switch.
6-20. FUEL TANK REPLACEMENT . Replace the fuel tank in accordance with paragraph 2-18.
6-21. FUEL TANK REPAIR.
Remove. Remove the fuel tank in accordance with paragraph 2-18.
Although not as flammable as gasoline, diesel fuel is volatile and the vapor will bum or
explode. To avoid injury to personnel, do not weld the fuel tank, or perform other operations
that may produce sparks, until the tank is rendered safe.
Cleaning. Before performing repair operations, the fuel tank should be cleaned and rendered safe as follows: (1)
Before starting the cleaning procedure, inspect for possible leak areas as indicated by fuel seepage, or wet spots.
Mark these areas for further inspection and testing.
Steam or vapor pressure cleaning creates hazardous noise levels, and may cause severe
bums. Eye, skin, and ear protection is required.
Steam dean the tank for at least 4 hours. During this time, high pressure steam should be introduced into
all openings to vaporize and flush away all residual fuel.
