M/T Oil Pump Clearance Inspection

1. Measure the thrust clearance between the oil pump gears (A) and clutch housing (B) with a straight edge (C) and a feeler gauge (D).
   Standard: | 0.03−0.13 mm (0.001−0.005 in.)
   Service Limit: | 0.15 mm (0.006 in.)

1. Measure the side clearance between the outer rotor (A) and clutch housing (B) with a feeler gauge (C).
   Standard: | 0.1−0.2 mm (0.004−0.008 in.)
   Service Limit: | 0.22 mm (0.009 in.)

1. Measure the side clearance between the outer rotor (A) and inner rotor (B) with a feeler gauge (C).
   Standard: | below 0.14 mm (0.006 in.)
   Service Limit: | 0.2 mm (0.008 in.)
If clearance is not within standard, replace the oil pump outer and inner rotors. |
