Fuel injection nozzle (1) Tighten the union nut of the high pressure fuel line (not shown) to the following torque. ... 22 N m (16 lb ft) (2) Tighten the banjo bolts of the leak off tubing (not shown) to the following torque. ... 9.0 N m (80 lb in) (3) Tighten the nut of the fuel injection nozzle to the following torque. ... 30 N m (22 lb ft)Note: When the fuel injection nozzle is installed, put a 2.0 mm (0.08 inch) bead of 4C-5591 Anti-Seize Compound on the first two threads of the union nut. (4) Wire clip (5) Seat washerNote: 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 seat washer (5) .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, "Fuel Injection Nozzle - Test".

Do not use dirty test fluids when you test fuel injection nozzles. Also, do not test fuel injection nozzles unless you have the correct service tools.The use of dirty test fluids and the use of incorrect service tools will result in damage to fuel injection nozzles.
Caterpillar Inc. recommends the use of SAEJ-967 Calibration Oil (ISO 4113) for testing the fuel injection nozzles. The oil is available in 5 gallon containers ( 6V-6068 Calibration Fluid ) and 55 gallon containers ( 6V-6067 Calibration Fluid ).Refer to the Testing and Adjusting Module, "Fuel System" topic for additional information.
