Assembly Procedure

Assembly Procedure





1. Apply ATF to new oil seal and install it onto oil pump housing using the SST.





2. Measure the clearance between the end of the oil pump housing and the outer rotor and inner rotor at four places along their circumferences.

Clearance between the end of the oil pump housing and the outer rotor and inner rotor
Standard: 0.04-0.05 mm (0.0016-0.0019 in)
Maximum: 0.05 mm (0.002 in)

^ If not as specified, replace the oil pump.





3. Measure the clearance between the outer rotor and the inner rotor.

Clearance between the outer rotor and the inner rotor
Standard: 0.02-0.11 mm (0.0008-0.0043 in)
Maximum: 0.12 mm (0.0047 in)

^ If not within the specification, replace the oil pump.
4. Apply ATF to the outer and inner rotors.
5. Align the marks and install the outer and inner rotors.





6. Install the oil pump flange.
7. Mount the oil pump cover onto the oil pump housing.





8. Tighten the bolts evenly and gradually in the order shown.

Tightening torque:
8.1-10.9 Nm (83-111 kgf-cm, 72-96 in. lbf.)





9. Apply ATF to new O-ring and install it onto the oil pump housing.

O-ring inner diameter:
209.5 mm (8.248 in)





10. Apply ATF to new seal rings and install them onto the oil pump cover.

Seal ring inner diameter:
47.1 mm (1.854 in)
