OIL PUMP DISASSEMBLY


  1. REMOVE FRONT OIL PUMP BODY O-RING


    1. A003ADN

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

  2. SECURE OIL PUMP ASSEMBLY


    1. A003HH0

      Place the oil pump assembly on the torque converter assembly.

  3. REMOVE CLUTCH DRUM OIL SEAL RING


    1. A003C5E

      Remove the 2 clutch drum oil seal rings from the oil pump assembly.

  4. INSPECT FRONT OIL PUMP DRIVE GEAR ROTATION


    1. Install the oil pump assembly to the torque converter assembly.

    2. A003DAM

      Check that the front oil pump drive gear rotates smoothly.

    3. Remove the oil pump assembly from the torque converter assembly.

  5. REMOVE FRONT OIL PUMP PLATE


    1. A003HR7

      Using a T30 "TORX" socket wrench, remove the 3 screws and front oil pump plate from the oil pump assembly.

  6. REMOVE STATOR SHAFT ASSEMBLY


    1. A003EX7

      Using a T30 "TORX" socket wrench, remove the 7 screws and stator shaft assembly from the front oil pump body sub-assembly.

  7. INSPECT STATOR SHAFT ASSEMBLY


    1. A003CPW

      Using a dial indicator, measure the inside diameter of the stator shaft assembly bushing.

      Maximum inside diameter
      22.227 mm (0.875 in.)

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

  8. INSPECT CLEARANCE OF OIL PUMP ASSEMBLY


    1. A003CRC

      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 body clearance
      0.10 to 0.17 mm (0.00394 to 0.00669 in.)

      If the body clearance is more than the standard clearance, check the front oil pump drive gear, front oil pump driven gear and front oil pump body sub-assembly.

    3. A003I62

      Using a feeler gauge, measure the clearance between the front oil pump driven gear teeth and the front oil pump drive gear teeth.

      Standard tip clearance
      0.07 to 0.15 mm (0.00276 to 0.00590 in.)

      If the tip clearance is more than the standard clearance, check the front oil pump drive gear, front oil pump driven gear and front oil pump body sub-assembly.

    4. A003E17

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

      Standard side clearance
      0.03 to 0.05 mm (0.00118 to 0.00196 in.)

      If the side clearance is more than the standard thickness, check the front oil pump drive gear, front oil pump driven gear and front oil pump body sub-assembly.

  9. REMOVE FRONT OIL PUMP DRIVE GEAR


    1. A003B8X

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

  10. REMOVE FRONT OIL PUMP DRIVEN GEAR


    1. A003DA7

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

  11. REMOVE FRONT OIL PUMP OIL SEAL


    1. A003GGZE01
      Text in Illustration
      *a Protective Tape

      Using a screwdriver, remove the front oil pump oil seal from the front oil pump body sub-assembly.

      Note

      Do not damage the bushing or front oil pump body sub-assembly.

      Tech Tips

      Tape the screwdriver tip before use.

  12. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY


    1. A003C96

      Using a dial indicator, measure the inside diameter of the front oil pump body sub-assembly bushing.

      Maximum inside diameter
      38.138 mm (1.50 in.)

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