Use Tooling (A) to rotate the crankshaft so that number one piston is at top dead center position . Refer to System Operation, Testing and Adjusting, "Fuel Injection Timing - Check". Use Tooling (B) to lock the crankshaft so that number one piston is at top dead center position.
Remove plug (8) and remove O-ring seal (9) (not shown). Use Tooling (C) to lock fuel injection pump (10).
Place a suitable container below fuel injection pump (10) to catch any fuel that might be spilled.
Clean fuel injection pump (10) and the area around the fuel injection pump. Ensure that the area is free from contamination before beginning disassembly.
Loosen banjo bolt (7) to drain fuel from the fuel system. Remove banjo bolt (7). Remove sealing washers (6) and disconnect hose assembly (12) from fuel injection pump (10). Use Tooling (D) to plug the tube assembly with a new plug. Cap the port in the fuel injection pump with a new cap.
Disconnect plastic tube assembly (2), plastic tube assembly (4), and plastic tube assembly (5) from fuel injection pump (10).
Use Tooling (D) to plug the plastic tube assemblies. Cap the ports in the fuel injection pump with new caps.
Disconnect harness assembly (3) from the solenoid on fuel injection pump (10).Note: The harness assemblies should be positioned to avoid an obstruction to the fuel injection pump.
Disconnect harness assembly (1) from the sensor on fuel injection pump (10).
Remove fuel injection line (11) that connects fuel injection pump (10) to the fuel manifold. Refer to Disassembly and Assembly, "Fuel Injection Lines - Remove" for the correct procedure.Note: Discard the fuel injection line.
Use Tooling (D) to plug the open ports in the fuel injection pump and in the fuel manifold.
If necessary, remove the accessory drive. Refer to Disassembly and Assembly, "Accessory Drive - Remove and Install" for the correct procedure.
