OIL PUMP INSPECTION

PROCEDURE


  1. INSPECT OIL PUMP ASSEMBLY


    1. A01VAUN

      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 BODY AND GEAR SUB-ASSEMBLY


    1. A01VALW

      Inspect the body clearance.


      1. Push the driven gear to one side of the front oil pump body.

      2. Using a feeler gauge, measure the front oil pump body clearance.

        Standard clearance
        0.08 to 0.15 mm (0.00315 to 0.00590 in.)
        Maximum clearance
        0.15 mm (0.00590 in.)

        If the clearance is more than the maximum, replace the front oil pump drive gear, front oil pump driven gear or front oil pump body sub-assembly.

    2. A01VALD

      Inspect the side clearance.

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


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

        Standard side clearance
        0.035 to 0.05 mm (0.00138 to 0.00196 in.)
        Maximum side clearance
        0.05 mm (0.00197 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 (0.45493 to 0.45523 in.)
        3 11.564 to 11.571 mm (0.45528to 0.45555 in.)
        4 11.572 to 11.579 mm (0.45559 to 0.45586 in.)
        5 11.580 to 11.587 mm (0.45591 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 (0.45493 to 0.45523 in.)
        3 11.564 to 11.571 mm (0.45528to 0.45555 in.)
        4 11.572 to 11.579 mm (0.45559 to 0.45586 in.)
        5 11.580 to 11.587 mm (0.45591 to 0.45618 in.)

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

  3. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY


    1. A01V6TU

      Using a caliper gauge, measure the inside diameter of the front oil pump body bushing.

      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 more than the maximum, replace the front oil pump body sub-assembly.

  4. INSPECT STATOR SHAFT ASSEMBLY


    1. A01V9TQ

      Using a caliper gauge, measure the inside diameter of the stator shaft bushing.

      Standard inside diameter
      22.500 to 22.526 mm (0.88583 to 0.88684 in.)
      Maximum inside diameter
      22.570 mm (0.8886 in.)

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