Information:
1. Thoroughly clean the area around each fuel injection line connection before removal of any fuel injection lines. 2. Remove bolts (3) and (5) that fasten the mounting brackets to the cylinder head.3. Disconnect all fuel injection line nuts (2) at the fuel injection pump housing.
Do not let the tops of fuel injection nozzles (4) turn when fuel injection line nuts (6) are tightened. The nozzles will be damaged if the top of the nozzle turns in the body. The engine will be damaged if a defective fuel injection nozzle is used because the shape of fuel (spray pattern) that comes out of the nozzles will not be correct.
4. Use two wrenches, one to hold fuel injection nozzles (4) so they will not turn and one to disconnect fuel injection lines (1) from the nozzles.5. Remove fuel injection lines (1) from the engine. Put caps and plugs on the nozzles, fuel injection lines and fuel injection pump housing to keep dirt from entering the fuel system. The following steps are for installation of the fuel injection lines.6. Make sure the fuel injection lines are clean and dry.7. Put fuel injection lines (1) in position. Install all fuel injection line nuts (2) and (6) until they are finger tighten.8. Use a torque wrench and Tool (A) to tighten all fuel injection line nuts (2) to a torque of 41 7 N m (30 5 lb ft).
Do not let the tops of fuel injection nozzles (4) turn when the fuel injection lines are tightened. The nozzles will be damaged if the top of the nozzle turns in the body. The engine will be damaged if a defective fuel injection nozzle is used because the shape of fuel (spray pattern) that comes out of the nozzles will not be correct.
9. Use a wrench to hold fuel injection nozzles (4) so they will not turn. Use a torque wrench and Tool (A) to tighten all fuel injection line nuts (6) to a torque of 41 7 N m (30 5 lb ft).10. Install bolts (3) and (5) that fasten the mounting brackets to the cylinder head.11. Remove (bleed) the air from the fuel system. See the Operation & Maintenance Manual.
