[6] OIL PUMP

Rotor Lobe Clearance

1. Measure the clearance between the lobes of the inner rotor and

the outer rotor with a feeler gauge.

2. Measure the clearance between the outer rotor and the pump

body with a feeler gauge.

3. If  the  clearance  is  more  than  the  allowable  limit,  replace  the

rotor assembly of the oil pump.

Clearance between Rotor and Cover

1. Put a strip of plastigauge on the rotor face with grease.

2. Install the cover and tighten the screws.

3. Remove the cover carefully.

4. Measure the width that plastigauge becomes flat with the scale

to get the oil clearance.

5. If  the  clearance  is  more  than  the  allowable  limit,  replace  the

rotor assembly of the oil pump.
