Remove the pump cover and pump cover seal. Remove the outer side plate, pump cam ring, pump rotor, pump vanes, side plate and O-rings. Remove the snap ring, then remove the sub-valvefrom the pump housing. Remove the circlip, then remove the pump driveshaft by tapping the shaft end with the ptastic ham-mer. Remove the pump seal spacer and pump seal. 17-26 Inspection Flow Control Valve 1. Check the flow control valve for wear, burrs, and other damage to the edges of the grooves in thevalve. 97 model: FLOWCONTROL VALVE Check fordamage to edges. 98 - 0O mod€ls: FLOW CONTBOL VALVE Check for damageto edges. Insp€d the bore of the flow control valve tor scratchesor wear. Slip the valve back in the pump, and check that itmoves in and out smoothly. lf OK, go to step 4; ifnot, replace the pump as an assembly. The flowcontrolvalve is not available separately. CONTROL VALVE 4. Attach a hose to the end of the valve as shown. FLOW CONTROL VALVE HOSE www.emanualpro.com
5. Submerge the valve in a container of power steer-
ing fluid or solvent, and blow in the hose. lf air bub-
bles leak through the valve at less than 98 kPa
(1.0 kgflcm, 14.2 psi), repair it as follows (97 model).

adding shims under the check ball seat lf you found
shims in your valve, be sure you reinstall as many
as you took out.
lf the flow control valve tests OK, reinstall it in the
pump. It the flow control valve still leaks air, replace
the pump as an assembly. The flow control valve is
not available separately.
