OIL PUMP INSPECTION

PROCEDURE


  1. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY


    1. B001XGE

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

      Maximum Inside Diameter
      38.138 mm (1.50 in.)

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

  2. INSPECT STATOR SHAFT ASSEMBLY


    1. B001Y04

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

      Maximum Inside Diameter
      22.227 mm (0.875 in.)

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

  3. INSPECT CLEARANCE OF OIL PUMP ASSEMBLY


    1. B001WQN

      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. B001ZEN

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

      Standard Tip Clearance
      0.07 to 0.15 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. B001VV1

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

      Standard Side Clearance
      0.03 to 0.05 mm (0.00118 to 0.00196 in.)

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

    2. B001XFA

      Check that the front oil pump drive gear rotates smoothly.

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