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.

Lubricate the oil pump valves with Mopar® ATF +4 and install the valve (2), spring, and retainer (1) into the appropriate oil pump valve body (3) bore.

Install the T/C regulator valve (1), T/C limit valve (2), and regulator valve (3). The pump separator plate is heat treated and therefore may exhibit a blue color or other discoloration in some areas. This is normal.

Coat the gears (2, 6) with Mopar® ATF +4 and install into their original locations.Place the oil pump flapper valve (3) into its pocket in the pump housing, with the rounded edges facing down.Place the separator plate (1) onto the oil pump housing (4).Install the screws (7) to hold the separator plate (1) onto the oil pump housing (4). Tighten the screws to 4.5 N·m (40 in.lbs.).

Position the oil pump valve body (5) onto the locating dowels.Seat the two oil pump halves together and install all bolts finger tight.Torque all bolts down slowly starting in the center and working outward. The correct torque is 4.5 N·m (40 in.lbs.).Verify that the oil pump gears rotate freely and smoothly.Position the reaction shaft support (4) onto the oil pump valve body (6).Install and tighten the bolts to hold the reaction shaft support (4) to the oil pump valve body (5). The correct torque is 12 N·m (105 in.lbs.).
