Inspection

14. Check the pressure control valve for wear, burrs,

and other damage to the edges of the grooves in
the valve.

15. Inspect the bore of the pressure control valve on

the pump housing for scratches and wear.

16. Slip the pressure control valve back in the pump

housing, and check that it moves in and out
smoothly. If OK, go to step 17; if not, replace the
pump as an assembly. The pressure control valve
is not available separately.

17. Attach a hose (A) to the end of the pressure control

valve (B) as shown. Then submerge the pressure
control valve in a container of power steering fluid
or solvent (C), and blow in the hose.

• If air bubbles leak through the valve at less than

98 kPa (1.0 kgf/cm , 14.2 psi), replace the pump
as an assembly. The pressure control valve is not
available separately.

• If the pressure control valve is OK, set it aside for

reassembly later.

18. Inspect the ball bearing by rotating the outer race

slowly. If you feel any play (axial or radial) or
roughness, remove the faulty ball bearing (A), and
install a new one (B).

19. Inspect each part shown with an asterisk in the

Exploded View; if any of them are worn or
damaged, replace the pump as an assembly.
