    ------ WARNING! ------

    Improper assembly of parts that are spring loaded can cause bodily injury.

    To prevent possible injury, follow the established assembly procedure and wear protective equipment.


  1. Align the joints of sleeve bearings (8) to 45 ± 15 degrees from the centerlines of the bearing bores in oil pump body assembly (9). Use Tooling (A) to install sleeve bearings (8) in oil pump body assembly (9). The sleeve bearings must be 1.5 ± 0.5 mm (0.06 ± 0.02 inch) below the gear bore.

  2. Install hollow dowels (16) in pump cover assembly (4) at a distance of 6.0 ± 0.5 mm (0.24 ± 0.02 inch) above the face of the pump cover assembly.

  3. Align the joints of sleeve bearings (5) to 45 ± 15 degrees from the centerlines of the bearing bores in pump cover assembly (4). Use Tooling (A) to install sleeve bearings (5) in pump cover assembly (4). The sleeve bearings must be 1.5 ± 0.5 mm (0.06 ± 0.02 inch) below the face of the pump cover assembly.

  4. Apply clean engine oil to pump drive shaft assembly (7) and to idler shaft assemblies (6). Install the pump drive shaft assembly and the idler shaft assemblies in oil pump body assembly (9). Position pump cover assembly (4) onto the oil pump body assembly and install bolts (10).

  5. Install the dowels in pump cover assembly (2) at a distance of 6.0 ± 1.0 mm (0.24 ± 0.04 inch) above the surface of the cover assembly. Position gasket (3) and pump cover assembly (2) on oil pump body assembly (9). Install bolts (1).

    Note: The engine oil pump must turn freely after assembly. Turn the engine oil pump by hand.

  6. Apply clean engine oil on pressure relief spool (15). Install pressure relief spool (15) and spring (14) in the oil pump body assembly. Install gasket (13), relief valve cover (12), and bolts (11).

End By:

  1. Install the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Install".
