Tools Required

J 36660-A Torque/Angle Meter

1. Remove the engine front cover. Refer to Engine Front Cover Replacement .



2. Remove the 3 oil pump assembly retaining bolts (1, 2, 3) identified by the larger head size.
3. Slide the oil pump assembly off the nose of the crankshaft with the drive collar in place.
4. Clean and inspect the oil pump. Refer to Oil Pump Cleaning and Inspection in Engine Mechanical 4.6L-Unit Repair.

1. Install the oil pump drive spacer into the oil pump so that the drive flat engages the pump rotor.
2. Position the oil pump on the crankshaft.
3. Install the retaining bolts.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

4. Apply upward pressure on the pump while tightening the three retaining bolts. Tighten the bolts in the sequence (1, 2, 3) shown.
