Illustration 1 g00911852
The pump is shown with the optional logic control governor.Note: Parts that are inside of the fuel injection pump are only serviceable by an authorized Delphi dealer. Please consult your parts book for availability of parts on the outside of the pump that are not related to the settings of the fuel pump and for the possibility of remanufacturing options.Hub nut (not shown)Note: Do not release the hub nut from the fuel injection pump. The fuel pump hub is positioned to the pump shaft in order to ensure that the fuel pump is in the correct position for timing. If the hub is removed, the hub will need to be accurately positioned to the pump shaft. Accurate positioning requires the use of special equipment by a Caterpillar Dealer. (1) Tighten the locknut for the pivot to the following torque. ... 5.7 N m (50 lb in) (2) Tighten the adjustment nut for the throttle lever to the following torque. ... 5.7 N m (50 lb in) (3) Electrical connection for the stop solenoid

(4) Tighten the locking screw to the following torque. ... 12 N m (8.8 lb ft)The locking screw prevents the rotation of the drive shaft. Before the crankshaft is turned or the fuel injection pump is installed, move the locking spacer under locking screw (4). Refer to position (A) in Illustration 2. This position ensures that the drive shaft is released.Tighten the flange nuts for the fuel injection pump to the following torque. ... 28 N m (20 lb ft)Stanadyne Fuel Injection Pump (DB2 or DB4)

If the hub is removed, the hub will need to be accurately positioned to the pump shaft. Accurate positioning requires the use of special equipment by a Caterpillar Dealer. (1) Electrical connection for the stop solenoid (2) Tighten the fitting for the fuel return line connection to the following torque. ... 5 to 6 N m (44 to 53 lb in) (3) Tighten the high idle speed adjustment screw to the following torque. ... 4 to 4.5 N m (35 to 40 lb in) (4) Tighten the screw for the low idle speed adjustment to the following torque. ... 4 to 4.5 N m (35 to 40 lb in) (5) Tighten the flange nuts to the following torque. ... 28 N m (20 lb ft) (6) Adjustment screw for advance timing (7) Tighten the fittings for the fuel discharge to the following torque. ... 70.5 to 81.4 N m (52 to 60 lb ft) (8) Tighten the nuts for the high pressure fuel injection line to the following torque. ... 22 N m (16 lb ft) (9) Tighten the nut for the end cap to the following torque. ... 22 N m (16 lb ft)Tighten the nut for the drive gear to the following torque. ... 80 N m (60 lb ft)
The No. 1 cylinder must be at the top center position on the compression stroke before the fuel injection pump is installed. If the crankshaft needs to be rotated, the fuel injection pump must be mounted temporarily or the loose gear could cause damage to the front housing.
