OIL PUMP INSPECTION


  1. INSPECT FRONT OIL PUMP AND GEAR BODY SUB-ASSEMBLY


    1. A01EL4I

      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 FRONT OIL PUMP AND GEAR BODY SUB-ASSEMBLY


    1. A01EJ9G

      Push the driven gear to one side of the body.

    2. Using a feeler gauge, measure the clearance.

      Standard clearance
      0.08 to 0.15 mm (0.00315 to 0.00591 in.)
      Maximum clearance
      0.15 mm (0.00591 in.)

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

    3. A01EMQB

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

      Standard side clearance
      0.025 to 0.04 mm (0.000984 to 0.00157 in.)
      Maximum side clearance
      0.04 mm (0.00157 in.)
      Drive Gear Thickness
      Mark Thickness
      1 11.547 to 11.555 mm (0.45461 to 0.45492 in.)
      2 11.555 to 11.563 mm (0.45492 to 0.45524 in.)
      3 11.564 to 11.571 mm (0.45527 to 0.45555 in.)
      4 11.572 to 11.579 mm (0.45559 to 0.45587 in.)
      5 11.580 to 11.587 mm (0.45590 to 0.45618 in.)
      Driven Gear Thickness
      Mark Thickness
      1 11.547 to 11.555 mm (0.45461 to 0.45492 in.)
      2 11.555 to 11.563 mm (0.45492 to 0.45524 in.)
      3 11.564 to 11.571 mm (0.45527 to 0.45555 in.)
      4 11.572 to 11.579 mm (0.45559 to 0.45587 in.)
      5 11.580 to 11.587 mm (0.45590 to 0.45618 in.)

  3. INSPECT FRONT OIL PUMP AND GEAR BODY SUB-ASSEMBLY


    1. A01ELZ0

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

      Standard inside diameter
      43.122 to 43.138 mm (1.69771 to 1.69834 in.)
      Maximum inside diameter
      43.188 mm (1.7003 in.)

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

  4. INSPECT STATOR SHAFT ASSEMBLY


    1. A01ELYM

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

      Standard inside diameter
      22.500 to 22.526 mm (0.88583 to 0.88685 in.)
      Maximum inside diameter
      22.570 mm (0.8886 in.)

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