Ford Rack and Pinion Pressure Port Check Valve Installation

Tech Tip: Ford Rack and Pinion Pressure Port Check Valve Installation

The original rack and pinion may have a check valve and retaining clip in the pressure port. The valve prevents fluid from backing up into the pump when the engine is shut off. Not all original units have a check valve, but if one is present, it should be transferred to the replacement rack.

Application:
Ford Rack and Pinions: 22-217, 218, 220, 231, 232, 234, 235, 239, 241, 242, 243, 244, 246, 253, 264, 268, 271, 272, 276, 283, 294

Problem:
Correctly transferring and installing pressure port check valve.

Solution:
The original rack and pinion may have a check valve and retaining clip in the pressure port. See graphic below for a typical installation. The valve prevents fluid from backing up into the pump when the engine is shut off. Not all original units have a check valve, but if one is present, it should be transferred to the replacement rack. Note also that they don’t always have a retaining clip. The installation will be successful without the clip; it’s there to hold the valve in place during installation and to prevent the valve from falling out if the lines are serviced. If the clip is reused, be very careful not to damage port threads. The most important thing is to install the check valve in the pressure port, being careful to orient the valve as shown.

CAUTION: Pressure and Return ports are the same thread size. Refer to ProTech PT 22-0007 to determine which port is the pressure port.

Ride Height Sensors

If one of these sensors is replaced, it must be calibrated after it is installed.

Ride-height sensors not only measure the position of the suspension, but also the rate of movement. They are supplied with a voltage of around 5 volts. The signal voltage is changed as a magnet moves past a coil. Most sensors have three wires — ground, power and signal.

Internally, it is difficult to damage one of these sensors. Externally, the linkage that connects the sensor to the suspension arm can also be damaged. The connector can be damaged and cause a short or open and a code will be set. If one of these sensors is replaced, it must be calibrated after it is installed.
