Typical exampleNote: A new fuel injection pump is supplied, locked in the correct position. Do not unlock the fuel injection pump before installation.
If the fuel injection pump timing has been lost, it is possible to reset the fuel injection pump timing. Follow Step 1.a through Step 1.e in order to reset the fuel injection pump timing.
Loosen locking screw (22) and slide spacer (21) to Position (AA) . Tighten locking screw (22) to a torque of 9 N m (80 lb in). Placing the spacer into Position (AA) will prevent the locking screw from tightening against the shaft of the fuel injection pump.The fuel injection pump is now unlocked.
Position Tooling (E) onto the shaft of fuel injection pump (1) . Align the lever of Tooling (E) with Keyway (Y) and engage the lever into the keyway.Note: The lever of Tooling (E) should be a close fit in the keyway. If the lever is a loose fit in the keyway, It is not possible to reset the fuel injection pump timing.
Rotate the shaft of the fuel injection pump and engage the pin of Tooling (E) into Hole (Z) .The fuel injection pump timing is now set in the correct position.
Loosen locking screw (22) and slide spacer (21) to Position (BB) . Tighten locking screw (22) to a torque of 9 N m (80 lb in). The locking screw is now tightened against the shaft of the fuel injection pump.The fuel injection pump is now locked.
Remove Tooling (E) .

Inspect Bore (X) in front housing (20) for damage. If the bore is damaged, replace the front housing. Refer to Disassembly and Assembly, "Housing (Front) - Remove" and Disassembly and Assembly, "Housing (Front) - Install".
Use Tooling (F) to lubricate a new O-ring seal (17) . Install the O-ring seal onto fuel injection pump (1) .
Align fuel injection pump (1) with front housing (20) . Carefully install the fuel injection pump to the front housing.Note: The fuel injection pump should be supported by hand until the bolts are installed.
Install bolts (18) and new sealing washers (19) . Tighten the bolts to a torque of 25 N m (18 lb ft).Note: One sealing washers should be installed to each bolt.
If necessary, use Tooling (A) in order to rotate the crankshaft so that number one piston is at top dead center on the compression stroke. Refer to System Operation, Testing and Adjusting, "Finding Top Center Position for No.1 Piston".
Use Tooling (B) in order
