OIL PUMP(for 2GR) INSPECTION

PROCEDURE


  1. INSPECT STATOR SHAFT SPRING SUB-ASSEMBLY


    1. A01R4GCC02
      *a Straightedge

      Using a vernier caliper and straightedge, measure the distance between the end of the spring of the stator shaft spring sub-assembly and the straightedge.

      Standard Distance
      6.52 mm (0.257 in.)

      If the distance is greater than specified, replace the stator shaft spring sub-assembly.

  2. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY


    1. A01R4EC

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

      Maximum Inside Diameter
      45.078 mm (1.77 in.)

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

  3. INSPECT STATOR SHAFT ASSEMBLY


    1. A01R3C8

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

      Maximum Inside Diameter (Front Side)
      21.527 mm (0.848 in.)
      Maximum Inside Diameter (Rear Side)
      35.251 mm (1.39 in.)

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

  4. INSPECT OIL PUMP ASSEMBLY CLEARANCE


    1. A01R4I7

      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 between the front oil pump driven gear and front oil pump body sub-assembly.

      Standard Clearance
      0.10 to 0.17 mm (0.00394 to 0.00669 in.)

      • If the clearance is not as specified, replace the front oil pump drive gear, front oil pump driven gear and front oil pump body sub-assembly.

    3. A01R5XD

      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
      0.07 to 0.15 mm (0.00276 to 0.00591 in.)

      • If the tip clearance is not as specified, replace the front oil pump drive gear, front oil pump driven gear and front oil pump body sub-assembly.

    4. A01R6PX

      Using a 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.)

      • If the side clearance is not as specified, replace the front oil pump drive gear, front oil pump driven gear and front oil pump body sub-assembly.

      Tech Tips

      There are 7 front oil pump drive gears and front oil pump driven gears of different thicknesses.

      Front Oil Pump Drive Gear Thickness
      Part No. Mark Thickness
      35321-50080 0 11.636 to 11.642 mm (0.45811 to 0.45835 in.)
      35321-50090 1 11.643 to 11.649 mm (0.45838 to 0.45862 in.)
      35321-50100 2 11.650 to 11.656 mm (0.45866 to 0.45890 in.)
      35321-50110 3 11.657 to 11.663 mm (0.45894 to 0.45917 in.)
      35321-50120 4 11.664 to 11.670 mm (0.45921 to 0.45945 in.)
      35321-50130 5 11.671 to 11.677 mm (0.45949 to 0.45972 in.)
      35321-50140 6 11.678 to 11.684 mm (0.45976 to 0.46000 in.)
      Front Oil Pump Driven Gear Thickness
      Part No. Mark Thickness
      35322-50080 0 11.636 to 11.642 mm (0.45811 to 0.45835 in.)
      35322-50090 1 11.643 to 11.649 mm (0.45838 to 0.45862 in.)
      35322-50100 2 11.650 to 11.656 mm (0.45866 to 0.45890 in.)

  5. INSPECT FRONT OIL PUMP DRIVE GEAR ROTATION

    A01R38N

    1. Install the oil pump assembly to the torque converter assembly.

    2. Check that the front oil pump drive gear rotates smoothly.

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