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 (New):
    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 (New):
    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 (New) :
    0.14 mm (0.006 in.)
    Service Limit:
    0.2 mm (0.008 in.)

  1. If the clearance is not within the standard, replace the oil pump outer and inner rotors.
