    *1 Feeler Gauge

    1. Check the tip clearance.


      1. Using a feeler gauge, measure the clearance between the tips of the drive rotor and driven rotor.

        Standard tip clearance
        0.08 to 0.16 mm (0.0031 to 0.0063 in.)
        Maximum tip clearance
        0.21 mm (0.0083 in.)

        If the tip clearance is greater than the maximum, replace the oil pump.

      *1 Feeler Gauge

      Check the body clearance.


      1. Using a feeler gauge, measure the clearance between the driven rotor and oil pump body.

        Standard body clearance
        0.10 to 0.18 mm (0.0039 to 0.0071 in.)
        Maximum body clearance
        0.20 mm (0.0079 in.)

      *1 Feeler Gauge
      *2 Steel Square

      Check the side clearance.


      1. Using a feeler gauge and steel square , measure the clearance between the rotors and steel square.

        Standard side clearance
        0.03 to 0.09 mm (0.0012 to 0.0035 in.)
        Maximum side clearance
