OIL PUMP DISASSEMBLY


  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. REMOVE STATOR SHAFT ASSEMBLY


    1. A01EMST

      Using a "TORX" wrench (T30), remove the 16 bolts and stator shaft assembly from the front oil pump body sub-assembly.

      Note

      Keep the gears in the order of installation.

  3. 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 front 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.)
