Oil Pump

WARNING: This page is about a different variant/trim than selected.

NOTE: 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.

Position the oil pump valve body (5) onto the locating dowels. See Fig 4.
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). See Fig 4.
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.). See Fig 4.
