OIL PUMP DISASSEMBLY


  1. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY


    1. A01G4P1

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

      Note

      Be careful not to damage the front oil pump oil seal lip.

  2. REMOVE STATOR SHAFT ASSEMBLY


    1. A01G9JJ

      Using a "TORX" socket 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 they were removed.

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


    1. A01G6TU

      Push the front oil pump driven gear to one side of the front oil pump body sub-assembly.

    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. A01G70E

      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.)
      Front Oil Pump 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.)
      Front Oil Pump 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


    1. A01G4UO

      Remove the front oil pump body O-ring from the front oil pump body sub-assembly.

  5. REMOVE FRONT OIL PUMP DRIVE GEAR


    1. A01G9O6

      Remove the front oil pump drive gear from the front oil pump body sub-assembly.

  6. REMOVE FRONT OIL PUMP DRIVEN GEAR


    1. A01G7ZS

      Remove the front oil pump driven gear from the front oil pump body sub-assembly.

  7. REMOVE FRONT OIL PUMP OIL SEAL


    1. A01G4WIE01

      Secure the front oil pump body sub-assembly in a vise between aluminum plates.

      Note

      Do not overtighten the vise.

    2. Using SST, remove the front oil pump oil seal from the front oil pump body sub-assembly.
