5. Submerge the valve in a container of power steering

fluid or solvent, and blow in the hose. If air bubbles

leak through the valve at less than 98 kPa

(1.0 kgf/cm2,14.2 psi), repair it as follows.

6. Hold the bottom end of the valve with a open end

wrench.

7. Unscrew the seat in the top end of the valve, and

remove any shims, the relief check ball, relief valve

and relief valve spring.

8. Clean all the parts in solvent, dry them off, then

reassemble and retest the valve. If the flow control

valve tests OK, reinstall it in the pump. If the flow con-

trol valve still leaks air, replace the pump as an assem-

bly. The flow control valve is not available separately.

NOTE: If necessary, relief pressure is adjusted at

the factory by adding shims under the check ball

seat. If you found shims in your valve, be sure you

reinstall as many as you took out.

3. Install the new ball bearing using a press as shown.
2. Remove and discard the ball bearing using a press

as shown.
Ball Bearing Inspection/Replacement:

1. Inspect the ball bearing by rotating the outer race

slowly. If you feel any play (axial or radial) or rough-

ness is felt, replace the ball bearing.ProCarManuals.com
