OIL PUMP / ASSEMBLY
1. Clean and inspect all components. Make sure that all passages are thoroughly cleaned and are free from dirt or debris. Make sure that all valves move freely in their proper bore. Make sure that all gear pockets and bushings are free from excessive wear and scoring. Replace the oil pump if any excessive wear or scoring is found.
2. Coat the gears with Mopar ATE +4, type 9602, and install into their original locations.
3. Lubricate the oil pump valves with Mopar ATE +4, type 9602, and install the valve, spring and retainer into the appropriate oil pump valve body bore (Fig. 106) (Fig. 107).
4. Place the separator plate onto the oil pump body (Fig. 105).
5. Install the screws to hold the separator plate onto the oil pump body (Fig. 105). Tighten the screws to 4.5 Nm (40 in. lbs.).
6. Position the oil pump cover onto the locating dowels (Fig. 104).
7. Seat the two oil pump halves together and install all bolts finger tight.
8. Torque all bolts down slowly starting in the center and working outward. The correct torque is 4.5 Nm (40 in. lbs.).
9. Verify that the oil pump gears rotate freely and smoothly.
10. Position the reaction shaft support into the oil pump (Fig. 104).
11. Install and torque the bolts to hold the reaction shaft support to the oil pump (Fig. 104). The correct torque is 12 Nm (105 in. lbs.).
