  4. INSPECT CLEARANCE OF OIL PUMP ASSEMBLY


    1. A01CBHGE02

      Push the driven gear to one side of the body. Using a feeler gauge, measure the clearance.

      Standard body clearance
      0.10 to 0.17 mm (0.0039 to 0.0067 in.)
      Maximum body clearance
      0.17 mm (0.0067 in.)

      If the body clearance is greater than the maximum, replace the oil pump body.

    2. A01CDD7E01

      Measure the tip clearance between the driven gear teeth and drive gear teeth.

      Standard tip clearance
      0.07 to 0.15 mm (0.0028 to 0.0059 in.)
      Maximum tip clearance
      0.15 mm (0.0059 in.)

      If the tip clearance is greater than the maximum, replace the oil pump body.

    3. A01CEH3E01

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

      Standard side clearance
      0.02 to 0.05 mm (0.0008 to 0.0020 in.)
      Maximum side clearance
      0.05 mm (0.0020 in.)
      Standard Drive Gear Thickness
      Mark Thickness
      1 10.690 to 10.699 mm (0.4209 to 0.4212 in.)
      2 10.700 to 10.709 mm (0.4213 to 0.4216 in.)
      3 10.710 to 10.720 mm (0.4217 to 0.4220 in.)
      4 10.721 to 10.730 mm (0.4221 to 0.4224 in.)
      5 10.731 to 10.740 mm (0.4225 to 0.4228 in.)
      Standard Driven Gear Thickness
      Mark Thickness
      1 10.690 to 10.699 mm (0.4209 to 0.4212 in.)
      2 10.700 to 10.709 mm (0.4213 to 0.4216 in.)
      3 10.710 to 10.720 mm (0.4217 to 0.4220 in.)
      4 10.721 to 10.730 mm (0.4221 to 0.4224 in.)
      5 10.731 to 10.740 mm (0.4225 to 0.4228 in.)

      If the side clearance is greater than the maximum, replace the oil pump body.

  5. REMOVE FRONT OIL PUMP DRIVE GEAR


    1. A01CAL1E11

      Remove the front oil pump drive gear.

  6. REMOVE FRONT OIL PUMP DRIVEN GEAR


    1. A01CC5H

      Remove the front oil pump driven gear.

  7. REMOVE FRONT OIL PUMP BODY O-RING


    1. A01CAZ0E02
      *1 Protective Tape

      Using a screwdriver with its tip wrapped with protective tape, remove the front oil pump body O-ring from the oil pump body.

  8. REMOVE FRONT OIL PUMP OIL SEAL


    1. A01CC4KE01

      Mount the oil pump in a soft jaw vise.

    2. Using SST, remove the oil seal from the oil pump body.

      SST
      09308-00010

  9. INSPECT FRONT OIL PUMP AND GEAR BODY SUB-ASSEMBLY


    1. A01CDTIE01

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

      Standard inside diameter
      38.11 to 38.14 mm (1.5005 to 1.5015 in.)
      Maximum inside diameter
      38.19 mm (1.5035 in.)

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

  10. INSPECT STATOR SHAFT ASSEMBLY


    1. A01CCVXE01

      Set the stator shaft assembly by aligning each bolt hole.

    2. Using a T30 ''TORX'' socket, install the 11 bolts.
