OIL PUMP DISASSEMBLY


  1. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY


    1. A01HQH3

      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. A01HMNS

      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. A01HPY0

      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 oil pump body sub-assembly.

    3. A01HPF6

      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


    1. A01HO98

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

  5. REMOVE FRONT OIL PUMP DRIVE GEAR


    1. A01HMP6

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

  6. REMOVE FRONT OIL PUMP DRIVEN GEAR


    1. A01HQVP

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

  7. REMOVE FRONT OIL PUMP OIL SEAL


    1. A01HPYVE01

      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.
