b. Check the no strongly damage or wear on the bushing of the vane pump housing front and the vane pump shaft.
If necessary, replace the vane pump assy.
22. INSPECT VANE PUMP ROTOR AND VANE PUMP PLATES
a. Using a micrometer, measure the thickness of the vane pump plates.
Minimum thickness: 1.397 to 1.403 mm (0.0550 to 0.0552 inch)
b. Using a feeler gauge, measure the clearance between the vane pump rotor groove and the vane pump plate.
Maximum clearance: 0.03 mm (0.0012 inch)
If clearance exceeds 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.
If it gets symptom like lack smoothness, replace the vane pump assy.
b. 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 both end holes.
If it gets air leaks, replace the vane pump assy.
