Typical example
Install inner rotor (16) and install outer rotor (17). Used rotors should be installed in the original direction of rotation. Check the clearance between the outer rotor and the body of the oil pump. Check the clearance between the inner rotor and the outer rotor. Check the end play of the rotor assembly. Refer to Specifications, "Engine Oil Pump" for more information.
Lubricate the assembly of the oil pump with clean engine oil. Install front cover (15). Install bolts (14). Tighten the bolts to a torque of 26 N m (19 lb ft).
Ensure that the shaft of the oil pump is clean and dry. Position gear (13) onto the shaft. Install nut (12). Tighten the nut to a torque of 95 N m (70 lb ft). Note: Do not use a timing pin to lock the balancer in order to tighten nut (12).
Lubricate hub (9), thrust washer (11) and the bush of idler gear (10) with clean engine oil. Install hub (9) and thrust washer (11) to idler gear (10). Note: Ensure the correct orientation of the idler gear.
Install the assembly of the idler gear to balancer (1).
Ensure that the threads of bolt (8) are clean and dry. Apply Tooling (E) to the threads of the bolt. Install bolt (8). Tighten the bolt to a torque of 26 N m (19 lb ft).
Check the end play of idler gear (10). Refer to Specifications, "Engine Oil Pump".
