Typical example
Install a new O-ring seal (10) onto the fuel injection pump (4).
Install new washers (9) to bolts (8).
Align the holes in the fuel injection pump with the holes in the front housing. Install the fuel injection pump (4) to the housing.
Note: The fuel injection pump should be supported by hand until the bolts are installed.
Install bolts (8). Tighten the bolts to a torque of 25 N·m (18 lb ft).
Position support bracket (11) onto the cylinder block. Install bolt (14) finger tight.
Install bolt (13) and nut (12) finger tight.
Tighten bolt (14) to a torque of 44 N·m (32 lb ft). Tighten bolt (13) and nut (12) to a torque of 22 N·m (16 lb ft).
Note: Ensure that the fuel injection pump is not stressed as the bolts for the bracket are tightened.
Ensure that the No. 1 cylinder is at top dead center on the compression stroke. Refer to Systems Operation, Testing and Adjusting, "Fuel Injection Timing - Check". If necessary, use Tooling (A) in order to rotate the crankshaft so that number one piston is at the top center position on the compression stroke. Refer to Systems Operation, Testing and Adjusting, "Finding Top Center Position for No.1 Piston".
Note: Either Tooling (A) can be used. Use the Tooling that is most suitable.
Use Tooling (B) in order to lock the camshaft in the correct position. Use Tooling (C) in order to lock the crankshaft in the correct position. Refer to Disassembly and Assembly, "Gear Group (Front) - Remove and Install " for the correct procedure.
Install the fuel injection pump gear to fuel injection pump (4). Refer to Disassembly and Assembly, "Fuel Injection Pump Gear - Install" and refer to Disassembly and Assembly, "Gear Group (Front) - Remove and Install ".
Note: Ensure that the fuel injection pump is in the unlocked position after the installation of the fuel injection pump gear is completed.
