xB L4-1.5L (1NZ-FE) (2004)
b. Using a feeler gauge, measure the clearance between a side face of the vane pump rotor groove and the vane plates.
Maximum clearance: 0.03 mm (0.0012 inch)
If the clearance exceeds the maximum, replace the vane pump assy.
29. 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 under its own weight.
If necessary, replace the vane pump assy.
b. Check the flow control valve for leakage. Close one of the holes and apply compressed air of 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.
If necessary, replace the vane pump assy.
30. INSPECT FLOW CONTROL VALVE COMPRESSION SPRING
a. Using vernier calipers, measure the free length of the compression spring.
Minimum free length: 29.2 mm (1.150 inch)
If it is less than minimum, replace the vane pump assy.
31. INSPECT PRESSURE PORT UNION
If the union seat in the pressure port union is severely damaged, it may cause fluid leakage. In that case, replace the vane pump assy.
32. INSTALL VANE PUMP HOUSING OIL SEAL
a. Coat a new housing oil seal lip with power steering fluid.
b. Using SST and a press, install a new housing oil seal.
SST 09950-60010 (09951-00280), 09950-70010 (09951-07100)
NOTICE: Make sure that the oil seal is installed correctly.
