OIL PUMP INSPECTION

  1. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY

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

      A011V7C

      Note

      Be careful not to damage the oil seal lip.

  2. INSPECT CLEARANCE OF FRONT OIL PUMP AND GEAR BODY SUB-ASSEMBLY

    1. Push the driven gear to one side of the body.

      A011QVS

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

      A011UG6
      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 (0.4546 to 0.4549 in.)
      2 11.555 to 11.563 mm (0.4549 to 0.4552 in.)
      3 11.564 to 11.571 mm (0.4553 to 0.4556 in.)
      4 11.572 to 11.579 mm (0.4556 to 0.4559 in.)
      5 11.580 to 11.587 mm (0.4559 to 0.4562 in.)
      Driven Gear Thickness
      Mark Thickness
      1 11.547 to 11.555 mm (0.4546 to 0.4549 in.)
      2 11.555 to 11.563 mm (0.4549 to 0.4552 in.)
      3 11.564 to 11.571 mm (0.4553 to 0.4556 in.)
      4 11.572 to 11.579 mm (0.4556 to 0.4559 in.)
      5 11.580 to 11.587 mm (0.4559 to 0.4562 in.)

  3. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY

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

      A011UNE
      Standard inside diameter
      43.113 to 43.138 mm (1.6974 to 1.6983 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. Using a dial indicator, measure the inside diameter of the oil pump body bushing.

      A011R2W
      Standard inside diameter
      22.500 to 22.526 mm (0.8858 to 0.8868 in.)
      Maximum inside diameter
      22.570 mm (0.8886 in.)

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