Install the rotor assembly (17). Check the clearance between the outer rotor and the body. Check the clearance between the inner rotor and the outer rotor. Check the end play for the rotor assembly. Refer to Specifications, "Engine Oil Pump".
Lubricate the rotor assembly with clean engine oil. Install the cover (16). Install the setscrews (15). Tighten the setscrews to a torque of 28 N m (21 lb ft).
Ensure that the threads of the shaft are clean and dry. Position the oil pump gear (14) on the shaft. Install the nut (13). Tighten the nut to a torque of 95 N m (70 lb ft).
Use Tooling (D) and install a new bearing (11) in the idler gear (10).
Lubricate the bearing (11) with clean engine oil. Install the shaft (9) in the idler gear (10).
Position the idler gear (10) and the thrust washer (12) on the balancer group. Ensure that the threads of the setscrew (8) are clean and dry. Apply Tooling (F) to the threads of the setscrew and install the setscrew (8). Tighten the setscrew to a torque of 26 N m (19 lb ft).
Check the end play for the idler gear. Refer to Specifications, "Engine Oil Pump".
Check the backlash between the gear for the engine oil pump and the idler gear. Refer to Specifications, "Engine Oil Pump".
Ensure that the dowel (7) and the hollow dowel (6) are installed in the balancer (1).
Make sure that the No. 1 cylinder is at the top center compression stroke. Refer to Testing and Adjusting, "Finding Top Center Position for No. 1 Piston". Note: Install Tooling (A) through the camshaft gear. Install Tooling (B) into the crankshaft web.

Install the Tooling (E) in the cylinder block.
Illustration 3 g01152049
Install the Tooling (C). Ensure that the Tooling (C) is fully located in the drive shaft.
Carefully position the balancer group (1) onto the Tooling (E). Ensure that the teeth of the idler gear and the crankshaft gear are aligned. Note: The balancer weights must be pointing away from the cylinder block.
Install two setscrews (5) in the center of the balancer group. Tighten the setscrews to a torque of 54 N m (40 lb ft).
Remove the Tooling (E) and install the remaining setscrews (5). Tighten the setscrews to a torque of 54 N m (40 lb ft).
Remove the Tooling (A) from the camshaft gear. Remove the Tooling (B) from the crankshaft web.
Remove the Tooling (C). Rotate the crankshaft in order to ensure that the balancer group turns freely. End By:
Install the engine oil relief valve. Refer toDisassembly and Assembly, "Engine Oil Relief Valve - Remove and Install (Engine with Balancer Group)".
