Ensure that Tooling (B) is installed into Hole (X) in camshaft gear (1).
Ensure that shaft (10) of the fuel injection pump is clean and free from damage.
Ensure that the fuel injection pump is locked in the correct position. Refer to Disassembly and Assembly, "Fuel Injection Pump - Install".

Install a new spring washer (11) and install nut (8) to shaft (10) of the fuel injection pump. Apply sufficient pressure to fuel injection pump gear (2) in a counterclockwise direction in order to remove the backlash. Tighten nut (8) to a torque of 24 N m (212 lb in).
In order to unlock fuel injection pump (7), loosen locking bolt (5) in the fuel injection pump. Slide spacer (6) into unlock position. Tighten locking bolt (5) against the spacer to a torque of 12 N m (106 lb in). The spacer will prevent the locking bolt from tightening against the shaft of the fuel injection pump.
Remove Tooling (B) and Tooling (C).
Tighten nut (8) to a torque of 90 N m (66 lb ft).
Ensure that the backlash for gear (1), gear (2) and gear (9) is within specified values. Refer to the Specifications, "Gear Group (Front)" for further information.
