Alignment of timing marks
Illustration 4 g06323721Note: Ensure that the fuel pump gear is clean and free from wear of damage. If necessary, replace the fuel pump gear.
Install fuel pump gear (2). Ensure that the timing marks on gear (1), gear (2), and gear (9) are in alignment and that the mesh of the gears is correct.
Install the new spring washer and nut (8). Apply sufficient pressure to gear (2) in a counterclockwise direction to remove the backlash. Tighten nut (8) to a torque of 24 N m (212 lb in).
To unlock fuel injection pump (7), loosen locking bolt (5) in fuel injection pump (7). Slide spacer (6) into unlock position. Tighten locking bolt (5) against spacer (6) to a torque of 12 N m (106 lb in). Spacer (6) will prevent locking bolt (5) from tightening against the shaft of fuel injection pump (7).
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.

Install a new O-ring seal (3) to plug (4). Install plug (4) to the cylinder block. Tighten plug (4) to a torque of 21 N m (186 lb in).
Lubricate the teeth of the gears with clean engine oil.End By:
Install the front cover.
