Fuel injection nozzle
(1) Connection for the union nut of the fuel supply line
(2) Threaded hole for the banjo bolt of the leak off line
(3) Clamp
(4) Seal
(5) Spacer
(6) Fuel injector assembly
(7) Seat washer (1) Tighten the union nut of the high pressure fuel line (not shown) to the following torque: ... 18 N m (13.3 lb ft) (2) Tighten the banjo bolts of the leak off tubing (not shown) to the following torque: ... 9.5 N m (84 lb in) (3) Tighten the flange bolts (not shown) for the clamp to the following torque: ... 12 N m (9 lb ft)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 seat washer is installed. Do not reuse the seal (4) and the seat washer (7).Bench test the fuel injection nozzles at a temperature of 18 to 20 °C (64 to 70 °F).Note: Use clean 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.Refer to Testing And Adjusting, "Pressure Adjustment, Back Leakage Test, Nozzle and Seat Test".
