9. Check the housing-to-outer rotor radial clearance between the outer rotor (A) and pump housing (B). If the housing-to-outer rotor radial clearance exceeds the service limit, replace the oil pump assembly.

Housing-to-Outer Rotor Radial Clearance

Standard (New): | 0.10 - 0.18 mm (0.004 - 0.007 in.)
Service Limit | 0.20 mm (0.008 in.)

10. Inspect both rotors and the pump housing for scoring or other damage. Replace parts if necessary.

2. Grease the lips of the oil seal and apply oil to the new O-ring (B).
3. Install dowel pins (C), then align the inner rotor with the crankshaft and install the oil pump.
4. Clean the excess grease off the crankshaft and balancer shaft and check the seal for distortion.

18. Install the oil screen (D) with a new gasket (E).
