22. INSPECT VANE PUMP ROTOR AND VANE PUMP PLATES
a. Using a micrometer, measure the height, thickness and length of the vane pump plates.
Minimum height: 7.7 mm (0.303 inch)
Minimum thickness: 1.408 mm (0.05543 inch)
Minimum length: 11.993 mm (0.47216 inch)
b. Using a feeler gauge, measure the clearance between a side face of the vane pump rotor groove and vane pump plate.
Maximum clearance: 0.03 mm (0.0012 inch)
If it is more than the maximum, replace the vane pump assy.
23. INSPECT FLOW CONTROL VALVE
a. 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.
b. 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 assy.
