OIL PUMP DISASSEMBLY


  1. REMOVE AUTOMATIC TRANSMISSION CASE O-RING

    A01ENKN

    1. Remove the O-ring from the oil pump.

  2. FIX OIL PUMP ASSEMBLY

    A01EQ90E01

    1. Place the oil pump body on the torque converter.

  3. REMOVE CLUTCH DRUM OIL SEAL RING

    A01EQNZE01

    1. Remove the 3 oil seal rings.

  4. REMOVE STATOR SHAFT ASSEMBLY

    A01EQRHE01

    1. Remove the 17 bolts, and then remove the stator shaft from the oil pump body.

  5. REMOVE FRONT OIL PUMP BODY O-RING

    A01EPGC

    1. 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

    A01ES3H

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

      Standard inside diameter
      45.064 to 45.078 mm (1.774 to 1.775 in.)

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

  7. INSPECT STATOR SHAFT ASSEMBLY

    A01EQ53

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

      Standard inside diameter
      25.900 to 25.921 mm (1.020 to 1.021 in.)

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

  8. INSPECT CLEARANCE OF OIL PUMP ASSEMBLY

    A01ERGJ

    1. 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.

    3. A01EQ91

      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.

    4. A01EQLC

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

      Standard side clearance
      0.03 to 0.05 mm (0.00118 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.

      Tech Tips

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

      Drive and Driven Gears Thickness
      Mark Thickness
      0 11.636 to 11.642 mm (0.4581 to 0.4583 in.)
      1 11.643 to 11.649 mm (0.4584 to 0.4586 in.)
      2 11.650 to 11.656 mm (0.4587 to 0.4589 in.)
      3 11.657 to 11.663 mm (0.4589 to 0.4592 in.)
      4 11.664 to 11.670 mm (0.4592 to 0.4594 in.)
      5 11.671 to 11.677 mm (0.4595 to 0.4597 in.)
      6 11.678 to 11.684 mm (0.4598 to 0.4600 in.)

  9. REMOVE FRONT OIL PUMP DRIVE GEAR

    A01EOA2

  10. REMOVE FRONT OIL PUMP DRIVEN GEAR

    A01EP0O

  11. REMOVE FRONT OIL PUMP OIL SEAL

    A01ENDZE01

    1. Using a screwdriver, pry out the oil seal.

      Note

      Be careful not to damage the oil pump body.

      Tech Tips

      Wrap the tip of the screwdriver with tape.
