1. Oil seal lip for fault or other damage. Replace as necessary.
2. Outer and inner rotors, rotor plate and oil pump body for excessive wear or damage. Replace as necessary.

MEASURE





1. Radial clearance between outer rotor and case, using a feeler gage. If radial clearance exceeds its limit of 0.310 mm (0.0122 inch), then replace the outer rotor or case.





2. Side clearance using straight edge and feeler gage. The limit on side clearance is 0.15 mm (0.0059 inch).
