Ensure that all adjustments and repairs that are carried out to the fuel system are performed by authorised personnel that have the correct training.Before begining ANY work on the fuel system, refer to Operation and Maintenance Manual, "General Hazard Information and High Pressure Fuel Lines" for safety information. Refer to Systems Operation, Testing and Adjusting, "Cleanliness of Fuel System Components" for detailed information on the standards of cleanliness that must be observed during ALL work on the fuel system.
This procedure must be done before any of the following reasons:
Removal of the fuel injection pump
The bolts that hold the fuel injection pump to the front housing are loosened.
Set the number one piston at the top center piston on the compression stroke. Refer to Systems Operation, Testing and Adjusting, "Finding Top Center Position for the No.1 Piston" for the procedure.
Carefully remove the fuel injection pump from the front housing. Refer to Disassembly and Assembly, "Fuel Injection Pump - Remove" for the correct procedure.

To check the fuel injection pump timing, follow steps 3.a and 3.b.
Position Tooling (A) onto the shaft (8) of the fuel injection pump. Align the lever of Tooling (A) with the key slot (7). Engage the lever into the key slot.
Insert the locking pin of Tooling (A) into the hole (6) in fuel injection pump. If the locking pin can be inserted into the hole, the fuel injection pump timing is correct. If the locking pin cannot be inserted into the hole, the fuel injection pump timing is not correct.Note: There should be no resistance when the locking pin is inserted.
If the fuel injection pump timing has been lost follow steps 5 through 9 in order to reset the fuel injection pump timing.
If necessary, loosen the locking screw (4) on the fuel injection pump. Slide the spacer (5) into position (X). Tighten the locking screw (4) to a torque of 9 N m (80 lb in). This will prevent the locking screw from tightening against the shaft (8). The fuel injection pump is now unlocked.
Position Tooling (A) onto the shaft (8) of the fuel injection pump. Align the lever of Tooling (A) with the key slot (7) in the fuel injection pump. Engage the lever into the key slot.
Use the lever of Tooling (A) to rotate the shaft (8) until the pin of Tooling (A) can be engaged into the hole (6). Engage the pin of Tooling (A) into the hole.
Loosen the locking screw (4) in the fuel injection pump. Slide the spacer (5) into position (Y). Tighten the locking screw (4) against the shaft of the fuel injection pump to a torque of 9 N m (80 lb in). The fuel injection pump is now locked.
Remove Tooling (A).
Reinstall the fuel injection pump to the front housing. Refer to Disassembly and Assembly, "Fuel Injection Pump - Install" for the correct procedure. There are functional tests in order to ensure that
