OIL PUMP INSPECTION


  1. INSPECT STATOR SHAFT SPRING SUB-ASSEMBLY


    1. A015YM1E01

      Using a vernier caliper and straightedge, measure the distance between the spring end and the straightedge.

      Standard thickness
      6.52 mm (0.257 in.)

  2. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY


    1. A0161MG

      Using a caliper gauge, measure the inside diameter of the oil pump body bush.

      Maximum inside diameter
      45.078 mm (1.77 in.)

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

  3. INSPECT STATOR SHAFT ASSEMBLY


    1. A0161A2

      Using a caliper gauge, measure the inside diameter of the stator shaft bush.

      Maximum inside diameter
      Front side
      25.925 mm (1.02 in.)
      Rear side
      35.251 mm (1.39 in.)

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

  4. INSPECT CLEARANCE OF OIL PUMP ASSEMBLY


    1. A0160RZ

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

    2. Using a feeler gauge, measure the clearance between the driven gear and pump body.

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

      If the clearance is not as specified, replace the drive gear, driven gear and pump body.

    3. A01604B

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

      Standard tip clearance
      0.07 to 0.15 mm (0.00276 to 0.00591 in.)

      If the tip clearance is not as specified, replace the drive gear, driven gear and pump body.

    4. A0160IL

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

      Standard side clearance
      0.03 to 0.05 mm (0.00118 to 0.00197 in.)

      If the side clearance is not as specified, replace the drive gear, driven gear and pump body.

      Tech Tips

      There are 7 different thicknesses for the drive and driven gears.

      Standard Drive and Driven Gear Thickness
      Mark Thickness
      0 11.636 to 11.642 mm (0.45811 to 0.45835 in.)
      1 11.643 to 11.649 mm (0.45838 to 0.45862 in.)
      2 11.650 to 11.656 mm (0.45866 to 0.45890 in.)
      3 11.657 to 11.663 mm (0.45894 to 0.45917 in.)
      4 11.664 to 11.670 mm (0.45921 to 0.45945 in.)
      5 11.671 to 11.677 mm (0.45949 to 0.45972 in.)
      6 11.678 to 11.684 mm (0.45976 to 0.46000 in.)

  5. INSPECT OIL PUMP DRIVE GEAR ROTATION


    1. A015ZQM

      Place the oil pump assembly on the torque converter clutch.

    2. Make sure that the drive gear rotates smoothly.
