    *1 Front Housing
    *2 Vane Pump Shaft
    *a Bushing

    1. Using a micrometer and a caliper gauge, measure the oil clearance.

      Standard clearance
      0.03 - 0.05 mm (0.0012 - 0.0020 in.)
      Maximum clearance
      0.07 mm (0.0028 in.)

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

  2. INSPECT VANE PUMP ROTOR AND VANE PUMP PLATES

    *a Thickness
    *b Height
    *c Length

    1. Using a micrometer, measure the height, thickness and length of the vane plates.

      Minimum thickness
      1.397 - 1.403 mm (0.0550 - 0.0552 in.)
      Minimum height
      8.6 - 8.8 mm (0.339 - 0.346 in.)
      Minimum length
      14.991 - 15.001 mm (0.5902 - 0.5906 in.)

      *1 Feeler Gauge

      Using a feeler gauge, measure the clearance between the vane pump rotor grove and vane plate.

      Maximum clearance
      0.03 mm (0.0012 in.)

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

  3. INSPECT FLOW CONTROL VALVE

    A01KHER

    1. Coat the flow control valve with power steering fluid and check that it falls smoothly into the flow control valve hole by its own weight.

      *a Compressed Air

      Check the flow control valve for leakage. Close one of the holes and apply compressed air of 392 - 490 kPa (4 - 5 kgf*cm2, 57 - 71 psi) into the opposite side hole, and confirm that air does not come out from the end holes.

      If necessary, replace the vane pump assembly.

  4. INSPECT FLOW CONTROL VALVE COMPRESSION SPRING

    *1 Vernier Calipers

    1. Using vernier calipers, measure the free length of the spring.

      Minimum free length
      36.9 mm (1.453 in.)

      If it is not within the specification, replace the vane pump assembly.

  5. INSPECT PRESSURE PORT UNION


    1. If the pressure union seat in the pressure port union is remarkably damaged and it may cause fluid leakage, fluid leakage, replace the vane pump assembly.
