How does a rack and pinion steering system work?
Pump pressurizes fluid and sends it through the pump’s flow control valve to the pinion and valve on the rack and pinion assembly. See Fig. 1. Pinion and valve direct fluid to either side of the piston and rack, depending on turning direction of steering wheel. Piston and rack converts hydraulic pressure into linear force, reducing turning effort.
Why are the seals on a rack and Pinon important?
The seals around the rack and pinion are responsible for keeping the power steering fluid inside the mechanism. If the seals begin to wear out, fluid can seep into the bellows that encompass both ends of the rack.
What should be included in power steering kit?
The parts supplied for your particular installation should be included in the kit. Begin the installation by assembling the proper adapters into the pump and rack & pinion. The pressure port in the rack is the 1/2-20 port.
Where does the steering column go in rack and pinion?
There is a seal where your steering column enters the rack and pinion assembly, then a seal where each tie rod attaches. Each of these seals have to keep high-pressure power steering fluid contained while allowing the steering column to rotate and the tie rods to move as well.
How to replace power steering rack seals from the pinion through replacing in the pinion the seals You’d replace them using matching seals from the seal kit and the rack. If required, you’d use pliers to securely fix every seal to the shaft which is found in the pinion.
