Standard clearance:

0.021 to 0.043 mm (0.0008 to 0.0017 in.)

Maximum clearance:

0.07 mm (0.0028 in.)

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

2. INSPECT VANE PUMP ROTOR AND VANE PUMP PLATE

(a) Using a micrometer, measure the height, thickness and length of the vane pump plates.

Feeler Gauge

Maximum clearance:

0.025 mm (0.0012 in.)

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

3. INSPECT FLOW CONTROL VALVE

(a) Coat the flow control valve with power steering fluid and check that it falls

(a) Coat the flow control valve with power steering fluid and check that it falls smoothly into the flow control valve hole under its own weight.

(b) Check the flow control valve for leakage. Close one of the holes and apply compressed air of 392 to 490 kPa (4.0 to 5.0 kgf/cm2, 57 to 71 psi) to the hole on the opposite side. Confirm that the air does not flow out of the end holes.

Vernier Caliper

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 SUB-ASSEMBLY

(a) If the union seat in the pressure port union sub-assembly is badly damaged, it could cause fluid leakage, so replace the vane pump assembly.
