Note: The shaft of the fuel injection pump must remain locked until the timing gear (9) has been installed and tightened onto the shaft of the fuel injection pump. The locking screw (5) must remain locked until you are instructed to loosen the locking screw. The fuel injection pump must be returned to your Perkins Dealer if the shaft of the fuel injection pump was rotated accidentally.

Illustration 1 g01062058 Typical example Note: Do not lubricate the new O-ring (10). The O-ring should be installed dry.
- Install the new O-ring (10) onto the fuel injection pump. Position the fuel injection pump onto the front housing. Install the setscrews (13). Tighten the setscrews (13) to a torque of
25 N·m (18 lb ft) .Note: The two steps that follow are only required if the bracket (11) is installed on the fuel injection pump.
- Install the setscrew (15) and the bracket (11) onto the cylinder block if the bracket was previously removed. Ensure that the bracket (11) supports the fuel injection pump without applying any other external force on the fuel injection pump. Tighten the setscrew (15) to a torque of
44 N·m (32 lb ft) . - Install the bolt (12) and the nut (14). Tighten the bolt (15) to a torque of
22 ± 5.5 N·m (16 ± 4.1 lb ft) .Show/hide table
Illustration 2 g01011369 Typical example Note: 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 (8) must turn freely until contact is made with the fuel injection pump gear.
- Position the fuel injection pump gear (9) onto the shaft of the fuel injection pump. Install the washer and the nut (8). Rotate the fuel injection pump gear (9) in a counterclockwise direction in order to remove the backlash. Tighten the nut (8) to a torque of
24 N·m (17 lb ft) .Show/hide table
Illustration 3 g00956204 Typical example - Connect the harness assembly to the timing advance solenoid (7).
- Connect the harness assembly (2).
- Remove all of the dust caps from the connectors on the fuel injection pump. Remove all of the plugs from the fuel hose assemblies and from the tube assemblies.
- Connect the fuel line (3), the fuel return line (1), and the tube assembly (4) to the fuel injection pump.
- Loosen the locking screw (5). Move the spacer (6) in order to prevent the locking screw (5) from tightening against the shaft of the fuel injection pump. Tighten the locking screw (5) to a torque of
12 N·m (106 lb in) .Note: The spacer (6) must be correctly positioned and locking screw (5) must be tightened in order to prevent the locking screw from contacting the shaft of the fuel injection pump.
