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

2

,

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.

Reassembly

20. Install the new pump seal (A) (with its grooved side facing in) into the pump

housing (B) by hand, then drive it in using the driver and the attachment until
the seal is fully seated in the pump housing. Do not apply more than 1,370 N

22. Install the 40 mm internal snap ring (C) with its radiused edge facing out.
23. Coat the new 23.8 mm O-ring (A) with power steering fluid, then position it on

the bottom (B) of the pump housing.
