  1. Using a micrometer, measure the diameter (a) of the vane pump shaft.

  1. Using a caliper gauge, measure the inside diameter (b) of the front housing.

    NOTICE:
    Do not damage the bushing in the front housing.

  1. Subtract (a) from (b) to calculate the oil clearance.

    Maximum oil clearance:
    0.07 mm (0.0028 in.) or less
    If it is greater than the maximum, replace the vane pump assembly.


2. INSPECT VANE PUMP ROTOR AND VANE PUMP PLATES

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

    Maximum clearance:
    0.03 mm (0.0012 in.)
    NOTICE:
    1. If the clearance is more than the maximum, replace the vane pump plates, vane pump rotor and vane pump cam ring.
    2. Refer to the following table to select an appropriate combination of vane pump rotor, vane pump cam ring and vane pump plates.

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

    NOTICE:
    Make sure to use clean and dry air.

  1. If there is leakage, replace the flow control valve.

    NOTICE:
    1. Check the mark on the front housing and replace the flow control valve with one having the same mark as that of the front housing.
    2. Refer to the following table to select an appropriate combination of front housing and flow control valve.

      Combination of front housing and flow control valve:

      Front Housing Mark
      		Flow Control Valve Mark

  1. Coat the flow control valve with power steering fluid.

    NOTICE:
    Make sure to use new power steering fluid.

  1. Insert the flow control valve into the flow control valve installation hole of the front housing, and check that the flow control valve enters smoothly under its own weight.

  1. If the flow control valve does not enter the front housing smoothly, replace the flow control valve.



4. INSPECT FLOW CONTROL VALVE COMPRESSION SPRING

  1. Using a vernier caliper, measure the free length of the flow control valve compression spring.

    Minimum free length:
    32.3 mm (1.272 in.)
    If the length is less than the minimum, replace the flow control valve compression spring.


5. INSPECT PRESSURE PORT UNION

  1. If the union seat in the pressure port union is severely damaged, replace the pressure port union.
