      Remove the O-ring from the oil pump body.

    2. Remove the oil pump body from the torque converter clutch.

  6. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY


    1. A009AH9E01

      Using a dial indicator, measure the inside diameter of the oil pump body bush.

      Maximum inside diameter
      38.188 mm (1.50 in.)

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

  7. INSPECT STATOR SHAFT ASSEMBLY


    1. A009460E01

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

      Maximum inside diameter
      Front side
      21.577 mm (0.849 in.)
      Rear side
      32.08 mm (1.26 in.)

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

  8. INSPECT CLEARANCE OF OIL PUMP ASSEMBLY


    1. A009AEGE01

      Push the driven gear to one side of the body.

    2. Using a feeler gauge, measure the body clearance.

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

      • If the body clearance is more than the maximum, replace the drive gear, driven gear or pump body assembly. Replace the part or parts determined to be the most likely cause of the problem.

    3. A0095NUE01

      Using a feeler gauge, measure the tip clearance between the driven gear teeth and drive gear teeth.

      Standard tip clearance
      0.070 to 0.150 mm (0.00276 to 0.00591 in.)
      Maximum tip clearance
      0.150 mm (0.00591 in.)

      • If the tip clearance is more than the maximum, replace the drive gear, driven gear or pump body assembly. Replace the part or parts determined to be the most likely cause of the problem.

    4. A00992ME01

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

      Standard side clearance
      0.02 to 0.05 mm (0.000787 to 0.00197 in.)
      Maximum side clearance
      0.05 mm (0.00197 in.)

      If the side clearance is more than the maximum, replace the drive gear, driven gear or pump body assembly. Replace the part or parts determined to be the most likely cause of the problem.

      Tech Tips

      There are 5 different drive and driven gear thicknesses.

      Drive and Driven Gear Thickness
      Mark Thickness
      0 10.74 to 10.749 mm (0.42283 to 0.42319 in.)
      1 10.75 to 10.759 mm (0.42323 to 0.42358 in.)
      2 10.76 to 10.77 mm (0.42362 to 0.42401 in.)
      3 10.771 to 10.78 mm (0.42405 to 0.42441 in.)
      4 10.781 to 10.79 mm (0.42445 to 0.42480 in.)

  9. REMOVE FRONT OIL PUMP DRIVE GEAR

    A0099BVE01

  10. REMOVE FRONT OIL PUMP DRIVEN GEAR

    A0098UXE01

  11. REMOVE FRONT OIL PUMP OIL SEAL


    1. A009BXLE01

      Using a screwdriver, pry out the oil seal.

      Note

      Be careful not to damage the bushing or oil pump body.
