OIL PUMP (for Sedan) > INSPECTION



1. INSPECT STATOR SHAFT ASSEMBLY


C067787
  1. Using a dial indicator, measure the inside diameter of the stator shaft bushings.

    Standard inside diameter:
    21.500 to 21.526 mm (0.84646 to 0.84748 in.)

    Maximum inside diameter:
    21.526 mm (0.84748 in.)
    If the inside diameter is greater than the maximum, replace the stator shaft.


    C067788
  1. Install the input shaft assembly onto the stator shaft assembly and check that the input shaft assembly turns smoothly.

    NOTICE:
    Replace the stator assembly with a new one if it moves roughly or makes unusual noise.
    Inspect the input shaft's contact surface with the bearing when replacing, and replace the input shaft with a new one if any damage or discoloration is found.


2. INSPECT OIL PUMP GEAR CLEARANCE


C067791
  1. Measure the clearance between the tips of the driven gear teeth and the 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 sub-assembly.


    C067792
  1. Push the driven gear to one side of the body. Using a feeler gauge, measure the clearance.

    Standard body clearance:
    0.10 to 0.15 mm (0.0039 to 0.0059 in.)

    Maximum body clearance:
    0.15 mm (0.0059 in.)
    If the body clearance is greater than the maximum, replace the oil pump body sub-assembly.


    C067793
  1. Using a steel straight edge 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.)
    If the side clearance is greater than the maximum, replace the drive gear, driven gear or pump body.

    Drive gear thickness:
    No.
    Thickness mm (in.)
    1
    9.44 to 9.45 (0.3709 to 0.3713)
    2
    9.45 to 9.46 (0.3713 to 0.3717)
    3
    9.46 to 9.47 (0.3717 to 0.3721)
    4
    9.47 to 9.48 (0.3721 to 0.3725)
    5
    9.48 to 9.49 (0.3725 to 0.3729)

    Driven gear thickness:
    No.
    Thickness mm (in.)
    1
    9.44 to 9.45 (0.3709 to 0.3713)
    2
    9.45 to 9.46 (0.3713 to 0.3717)
    3
    9.46 to 9.47 (0.3717 to 0.3721)
    4
    9.47 to 9.48 (0.3721 to 0.3725)
    5
    9.48 to 9.49 (0.3725 to 0.3729)


3. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY


C067797
  1. Using a dial indicator, measure the inside diameter of the oil pump body bushing.

    Standard inside diameter:
    38.113 to 38.138 mm (1.50050 to 1.50149 in.)

    Maximum inside diameter:
    38.138 mm (1.50149 in.)
    If the inside diameter is greater than the maximum, replace the oil pump body sub-assembly.
