OIL PUMP INSPECTION


  1. INSPECT OIL PUMP ASSEMBLY


    1. A017DOW

      Turn the drive gear with 2 screwdrivers and make sure that it rotates smoothly.

      Note

      Be careful not to damage the oil seal lip.

  2. INSPECT CLEARANCE OF OIL PUMP ASSEMBLY


    1. A017DNDE03

      Push the driven gear to one side of the body.

    2. Using a feeler gauge, measure the clearance.

      Standard body clearance
      0.10 to 0.17 mm (0.0039 to 0.0067 in.)
      Maximum body clearance
      0.17 mm (0.0067 in.)

      If the body clearance is greater than the maximum, replace the oil pump body sub-assembly.

    3. A017CNX

      Using a feeler gauge, measure the tip clearance between the driven gear teeth and drive gear teeth.

      Standard tip clearance
      0.07 to 0.15 mm (0.0028 to 0.0059 in.)
      Maximum tip clearance
      0.15 mm (0.0059 in.)

      If the tip clearance is greater than the maximum, replace the oil pump body sub-assembly.

    4. A017ELZ

      Using a straightedge and feeler gauge, measure the side clearance of both gears.

      Standard side clearance
      0.02 to 0.05 mm (0.0008 to 0.0020 in.)
      Maximum side clearance
      0.05 mm (0.0020 in.)
      Drive gear thickness: mm (in.)
      Mark Thickness
      A 11.690 to 11.699 (0.4602 to 0.4606)
      B 11.700 to 11.709 (0.4606 to 0.4610)
      C 11.710 to 11.720 (0.4610 to 0.4614)
      D 11.721 to 11.730 (0.4615 to 0.4618)
      E 11.731 to 11.740 (0.4619 to 0.4622)
      Driven gear thickness: mm (in.)
      Mark Thickness
      A 11.690 to 11.699 (0.4602 to 0.4606)
      B 11.700 to 11.709 (0.4606 to 0.4610)
      C 11.710 to 11.720 (0.4610 to 0.4614)
      D 11.721 to 11.730 (0.4615 to 0.4618)
      E 11.731 to 11.740 (0.4619 to 0.4622)
  3. INSPECT FRONT OIL PUMP AND GEAR BODY SUB-ASSEMBLY


    1. A017FUS

      Using a dial indicator, measure the inside diameter of the oil pump body bushing.

      Standard inside diameter
      38.113 to 38.138 mm (1.5005 to 1.5015 in.)
      Maximum inside diameter
      38.188 mm (1.5035 in.)

      If the inside diameter is greater than the maximum, replace the oil pump body sub-assembly.

  4. INSPECT STATOR SHAFT ASSEMBLY


    1. A017BNG

      Using a dial indicator, measure the inside diameter of the stator shaft.

      Standard inside diameter
      21.500 to 21.526 mm (0.8465 to 0.8475 in.)
      Maximum inside diameter
      21.57 mm (0.8492 in.)

      If the inside diameter is greater than the maximum, replace the stator shaft.
