OIL PUMP INSPECTION

PROCEDURE


  1. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY


    1. A01MXYM

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

      Standard inside diameter
      38.138 mm (1.5015 in.)

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

  2. INSPECT STATOR SHAFT ASSEMBLY

    A01MY3T

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

      Standard inside diameter
      21.527 mm (0.8475 in.)

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

  3. INSPECT CLEARANCE OF OIL PUMP ASSEMBLY

    A01MV9Q

    1. Push the front oil pump driven gear to one side of the front oil pump body sub-assembly.

    2. Using a feeler gauge, measure the clearance.

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

      If the body clearance is more than the standard clearance, check the front oil pump drive gear, front oil pump driven gear and front oil pump body sub-assembly.

    3. A01MWO2

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

      Standard tip clearance
      0.070 to 0.150 mm (0.00276 to 0.00590 in.)

      If the tip clearance is more than the standard clearance, check the front oil pump drive gear, front oil pump driven gear and front oil pump body sub-assembly.

    4. A01MZ5Y

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

      Standard side clearance
      Drive Gear
      0.030 to 0.050 mm (0.00118 to 0.00197 in.)
      Driven Gear
      0.025 to 0.045 mm (0.00098 to 0.00177 in.)

    5. There are 7 different thicknesses for the oil pump drive gear and front oil pump driven gear.

      Front Oil Pump Drive Gear Thickness
      Part No. Mark

      Thickness

      mm (in.)
      35321-22120 0 9.946 to 9.952 (0.39157 to 0.39181)
      35321-22130 1 9.953 to 9.959 (0.39185 to 0.39209)
      35321-22140 2 9.960 to 9.966 (0.39213 to 0.39236)
      35321-22150 3 9.967 to 9.973 (0.39240 to 0.39264)
      35321-22160 4 9.974 to 9.980 (0.39268 to 0.39291)
      35321-22170 5 9.981 to 9.987 (0.39295 to 0.39319)
      35321-22180 6 9.988 to 9.994 (0.39323 to 0.39346)
      Front Oil Pump Driven Gear Thickness
      Part No. Mark

      Thickness

      mm (in.)
      35322-22120 0 9.946 to 9.952 (0.39157 to 0.39181)
      35322-22130 1 9.953 to 9.959 (0.39185 to 0.39209)
      35322-22140 2 9.960 to 9.966 (0.39213 to 0.39236)
      35322-22150 3 9.967 to 9.973 (0.39240 to 0.39264)
      35322-22160 4 9.974 to 9.980 (0.39268 to 0.39291)
      35322-22170 5 9.981 to 9.987 (0.39295 to 0.39319)
      35322-22180 6 9.988 to 9.994 (0.39323 to 0.39346)

      If the side clearance is more than the standard thickness, check the front oil pump drive gear, front oil pump driven gear and front oil pump body sub-assembly.

  4. INSPECT OIL PUMP DRIVE GEAR ROTATION


    1. A01MYEY

      Make sure that the drive gear rotates smoothly.

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