How to Replace a 1999 7 3L HI Pressure Oil Pump

The 7.3-liter Power Stroke engine that Ford manufactured from 1995 to 2002 is a diesel engine and typically has a turbocharger. It is most common in heavy Ford trucks from this period, and is the standard engine for the 1999 Ford F350 Super Duty with four-wheel drive. This engine requires a high-pressure oil pump, which is mounted directly to the cylinder block. The oil pump replacement procedure on a 1999 7.3-liter engine requires the removal of the radiator and the crankshaft damper.

Instructions

1

Disconnect the negative battery cable with a socket wrench to prevent anyone from starting the engine. Place a drain pan for the coolant under the radiator drain and open the drain. Allow the coolant to drain into the drain pan and replace the drain plug.

2

Remove the retainers for the air intake duct with a suitable pry tool and detach the air intake duct from the radiator support. Disconnect the expansion tank on top of the radiator with a socket wrench and remove the cover for the radiator support brace.

3

Disconnect the cooling fan and its shroud from the engine. Detach the hoses from the radiator and remove the retaining bolts for the radiator with a socket wrench. Remove the radiator from the vehicle.

4

Raise the vehicle with a jack and support it on jack stands. Disconnect the cover for the flywheel housing with a socket wrench and hold the flywheel in place with a suitable holding tool. Remove the mounting bolt for the crankshaft pulley bolt and disconnect the pulley. Detach the crankshaft vibration damper from the engine.

5

Assemble Step Plate Adapter D80L-630-A, Damper Wear Ring Remover T94T-6379-AH1, Bearing Collet Sleeve T77F-7025-C, Remover Tube T77J-7025-B and Forcing Screw T84T-7025-B to the crankshaft damper. Tighten the forcing screw to pull the damper wear ring from the hub.

6

Remove the retaining bolts that attach the oil pump to the cylinder block with a socket wrench. Detach the oil pump housing and its square gasket from the cylinder block.

7

Install the new oil pump and gasket to the cylinder block. Torque its mounting bolts to 14 ft. lbs with a torque wrench. Complete the oil pump installation by performing steps 2 through 5 in reverse order. Connect the negative battery terminal with a socket wrench. Start the engine and check for oil leaks.
