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
2
(1.0 kgf/cm ,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.
Ball Bearing Inspection/Replacement:

slowly. If you feel any play (axial or radial) or rough-
ness is felt, replace the ball bearing.
2. Remove and discard the ball bearing using a press
as shown.
3. Install the new ball bearing using a press as shown.
