The Ford non-integral linkage type power steering system is a hydraulically controlled system composed of an integral pump and fluid reservoir, a control valve, a power cylinder, connecting fluid lines, and the steering linkage. The hydraulic pump, which is driven by a belt turned by the engine, draws fluid from the reservoir and provides fluid pressure through hoses to the control valve and the power cylinder. There is a pressure relief valve to limit the pressures within the steering system to a safe level. After the fluid has passed from the pump to the control valve and the power cylinder, it returns to the reservoir.
Control Valve Centering Spring
- Raise the car and remove the spring cap attaching screws and the spring cap.
- Tighten the adjusting nut snugly (about 90-100 inch lbs.); then loosen the nut 1 / 4 turn (90°). Do not tighten the adjusting nut too tightly.
- Place the spring cap on the valve housing. Lubricate and install the attaching screws and washers. Tighten the screws to 72-100 inch lbs.
- Lower the car and start the engine. Check the steering effort using a spring scale attached to the steering wheel rim for a tightness of no more than 12 lbs.
