PROCEDURE


  1. INSPECT VANE PUMP SHAFT AND BUSH IN FRONT VANE PUMP HOUSING

      *a Outer Diameter
      *b Inner Diameter

      Using a micrometer, measure the outer diameter of the vane pump shaft.

    2. Using a vernier caliper, measure the inner diameter of the vane pump front housing bush.

    3. Calculate the oil clearance.

      Oil clearance = Inner diameter of the bush - Outer diameter of the shaft

      Maximum oil clearance
      0.07 mm (0.00276 in.)

      If the oil clearance is more than the maximum, replace the vane pump assembly.

  2. INSPECT VANE PUMP ROTOR AND VANE PUMP PLATE

      *a Thickness

      Using a micrometer, measure the thickness of the vane pump plates.

      Standard thickness
      1.405 to 1.411 mm (0.0554 to 0.0555 in.)

      If the thickness is not as specified, replace the vane pump assembly.

      *1 Feeler Gauge

      Using a feeler gauge, measure the clearance between the side of the vane pump rotor groove and the vane pump plates.

      Maximum clearance
      0.025 mm (0.00098 in.)

      If the clearance is more than the maximum, replace the vane pump assembly.

  3. INSPECT PRESSURE PORT UNION

    If the union seat in the pressure port union is severely damaged, it may cause fluid leakage. In that case, replace the vane pump assembly.
