      Maximum body clearance
      0.17 mm (0.00669 in.)

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

    2. A01EVRTE01

      Measure the tip 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.)
      Maximum tip clearance
      0.15 mm (0.00591 in.)

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

    3. A01EY95E01

      Using a 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.)
      Standard Drive Gear Thickness
      Mark Thickness
      1 10.690 to 10.699 mm (0.42087 to 0.42122 in.)
      2 10.700 to 10.709 mm (0.42126 to 0.42161 in.)
      3 10.710 to 10.720 mm (0.42165 to 0.42205 in.)
      4 10.721 to 10.730 mm (0.42209 to 0.42244 in.)
      5 10.731 to 10.740 mm (0.42248 to 0.42283 in.)
      Standard Driven Gear Thickness
      Mark Thickness
      1 10.690 to 10.699 mm (0.42087 to 0.42122 in.)
      2 10.700 to 10.709 mm (0.42126 to 0.42161 in.)
      3 10.710 to 10.720 mm (0.42165 to 0.42205 in.)
      4 10.721 to 10.730 mm (0.42209 to 0.42244 in.)
      5 10.731 to 10.740 mm (0.42248 to 0.42283 in.)

  5. REMOVE FRONT OIL PUMP DRIVE GEAR


    1. A01ET27E11

      Remove the front oil pump drive gear.

  6. REMOVE FRONT OIL PUMP DRIVEN GEAR


    1. A01ET27E10

      Remove the front oil pump driven gear.

  7. REMOVE FRONT OIL PUMP BODY O-RING


    1. A01EUNFE01

      Using a screwdriver, pry out the O-ring.

      Tech Tips

      Tape the screwdriver before use.

  8. REMOVE FRONT OIL PUMP OIL SEAL


    1. A01ETU6E01

      Mount the oil pump in a soft jaw vise.

      Note

      Be careful not to the damage the oil pump body in the vise.

    2. Using SST, tap out the oil seal from the oil pump body.

      SST
      09308-00010

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


    1. A01EXMUE01

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

      Standard inside diameter
      38.11 to 38.14 mm (1.50039 to 1.50157 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. A01EWPOE01

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

      Standard inside diameter
