(1)
Tighten the union nut of the high pressure fuel
line (not shown) t the following
torque: ........................................................22 Nm (16 lb-ft)
(2)
Tighten the banjo bolts of the leak off tubing
(not shown) to the following torque: .....................9.5 Nm
(84 lb-in)
(3)
Tighten the nut of the fuel injection nozzle to the
following torque: .......................................30 Nm (22 lb-ft)
NOTE: When the fuel injection nozzle is installed, put a
2.0 mm (.08 inch) bead of 4C-5591 Anti- Seize
Compound on the first two threads of the gland
nut. Do not rotate the fuel injection nozzle after
installation. The seal which is made by the anti-

NOTE: Remove the original seat washer from the
threaded hole for the fuel injection nozzle which is
located in the cylinder head. If the original seat
washer is not removed, the projection of the
nozzle will be incorrect when a new sea washer is
installed. Do not reuse the seat washer (5).
Bench test the fuel injection nozzles at a
temperature of 18 to 20 ° C (64 to 70 ° F).
NOTE: Use dean SAE J-967 oil (ISO 4113) when you are
conducting the test. The oil is available in 5
gallon containers (6V-6068 Calibration Fluid) and
55 gallon containers (6V-6067 Calibration Fluid).
If dirty oil is used for the test, the components of
the fuel injection nozzle will be damaged.
