OIL PUMP INSPECTION


  1. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY

    A01J5HEE01

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

      Maximum inside diameter
      38.188 mm (1.504 in.)

      • If the inside diameter is greater than the maximum, replace the oil pump body.

  2. INSPECT STATOR SHAFT ASSEMBLY

    A01J7K3E01

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

      Maximum inside diameter
      Front side
      21.577 mm (0.850 in.)
      Rear side
      32.08 mm (1.263 in.)

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

  3. INSPECT CLEARANCE OF OIL PUMP ASSEMBLY

    A01J5QPE01

    1. Push the driven gear to one side of the body.

    2. Using a feeler gauge, measure the clearance.

      Standard body clearance
      0.10 to 0.17 mm (0.00039 to 0.00067 in.)
      Maximum body clearance
      0.17 mm (0.0067 in.)

      • If the body clearance is greater than the maximum, replace drive gear, the driven gear or pump body.

    3. A01J5BDE01

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

      Standard tip clearance
      0.070 to 0.150 mm (0.0028 to 0.0059 in.)
      Maximum tip clearance
      0.150 mm (0.0059 in.)

      • If the tip clearance is greater than the maximum, replace drive gear, the driven gear or pump body.

    4. A01J6HVE01

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

      Standard side clearance
      0.02 to 0.05 mm (0.0008 to 0.002 in.)
      Maximum side clearance
      0.05 mm (0.002 in.)

    5. There are 5 different thicknesses for the drive and driven gears.

      Standard drive and driven gears thickness
      Mark Thickness
      0 10.74 to 10.749 mm (0.4228 to 0.4232 in.)
      1 10.75 to 10.759 mm (0.4232 to 0.4236 in.)
      2 10.76 to 10.77 mm (0.4236 to 0.424 in.)
      3 10.771 to 10.78 mm (0.4241 to 0.4244 in.)
      4 10.781 to 10.79 mm (0.4244 to 0.4248 in.)

      • If the side clearance is greater than the maximum, replace drive gear, driven gear or pump body.

  4. INSPECT FRONT OIL PUMP DRIVE GEAR ROTATION

    A01J3XHE01

    1. Make sure the drive gear rotates smoothly.

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