OIL PUMP DISASSEMBLY


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


    1. A01CFSH

      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. A01CCD0

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

      Note

      Keep the gears in the order of disassembly.

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


    1. A01CBHC

      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 0.00590 in.)
      Maximum clearance
      0.15 mm (0.00590 in.)

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

    3. A01CFV8

      Using a straightedge 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 (0.4546 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.)

  4. REMOVE FRONT OIL PUMP BODY O-RING

      Remove the O-ring from the oil pump body.

  5. REMOVE FRONT OIL PUMP DRIVE GEAR


    1. A01CDXL

      Remove the front oil pump drive gear from the oil pump body.

  6. REMOVE FRONT OIL PUMP DRIVEN GEAR


    1. A01CB7W

      Remove the front oil pump driven gear from the oil pump body.

  7. REMOVE FRONT OIL PUMP OIL SEAL


    1. A01CBZME01
