Use Tooling (D) in order to lubricate O-ring seal (10). Install a new O-ring seal (10) onto the fuel injection pump.
Install new washers to bolts (13).
Align the holes in the fuel injection pump with the holes in the front housing. Install the fuel injection pump to the housing. Note: The fuel injection pump should be supported by hand until the bolts are installed.
Install bolts (13). Tighten bolts (13) to a torque of 22 N m (16 lb ft).
Position support bracket (11) onto the cylinder block. Install bolt (15) finger tight.
Install bolt (12) and nut (14) finger tight.
Tighten bolt (12) and nut (14) to a torque of 22 N m (16 lb ft). Tighten bolt (15) to a torque of 44 N m (32 lb ft). Note: Ensure that the fuel injection pump is not stressed as the bolts for the bracket are tightened.
Illustration 2 g00956200Note: Ensure that the mating surfaces of the fuel injection pump gear and the shaft of the fuel injection pump are clean. Lubricate the threads of the shaft for the fuel injection pump. The nut must turn freely until contact is made with the fuel injection pump gear.
Position fuel injection pump gear (9) on the shaft of the fuel injection pump. Install the washer and nut (8). Rotate the fuel injection pump gear in a counterclockwise direction in order to remove the backlash. Tighten nut (8) to a torque of 24 N m (17 lb ft).

Connect the harness assembly to timing advance solenoid (7).
Connect harness assembly (2). Connect fuel line (3).
Connect fuel return line (1). Connect tube assembly (4) to the fuel injection pump.
Loosen bolt (5). Move spacer (6) in order to prevent bolt (5) from tightening against the shaft of the fuel injection pump. Tighten bolt (5) to a torque of 12 N m (106 lb in). Note: Spacer (6) must be correctly positioned and bolt (5) must be tightened in order to prevent the bolt from contacting the shaft of the fuel injection pump.
