Important: Replace the pressure relief valve spring when using the oil pump again.

1. Install the following items:

1.1. | The pressure relief valve

1.2. | The pressure relief valve spring

1.3. | The retaining pin

2. Coat the drive gear, the driven gear and the housing gear surfaces with clean engine oil.
3. Install the drive gear and the driven gear into the pump body. Align the matching marks on the gears. Install the smooth side of the gear toward the pump cover.
4. Install the oil pump cover.

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.

5. Install the oil pump cover bolts.

Tighten
Tighten the oil pump cover bolts to 12 N·m (106 lb in).

6. Inspect the oil pump for smoothness of operation by turning the oil pump driveshaft by hand.

Notice: Ensure the oil pump driveshaft is inspected for wear and/or damage, and replaced if necessary. An excessively worn or damaged oil pump driveshaft may fail causing severe engine damage.

7. Install the oil pump driveshaft and the new retainer.
