2 STEERING SYSTEM DESCRIPTION
The steering system consists of the steering
wheel and column assembly, a vane-type
hydraulic pump, tank, filter, interconnecting
system lines and hoses, integral power steering
gear, linkage and steering damper (Figure 1).
The steering linkage includes the pitman arm,
drag link, steering arm, tie rod arms and tie rod.
Hydraulic components are added to transmit,
increase and regulate steering control forces.
These elements are:
1. Steering stabilizer (damper);
2. A vane type hydraulic pump;
3. Hydraulic tank and hoses.
The steering stabilizer reduces road shocks and
vibrations in the system. The steering gearbox is
self-powered and provides movement with power
assistance to the left wheel.
Steering stability and tire wear are influenced by
wheels, hubs, tires, air suspension, brakes, front
suspension and front end alignment which are
all covered in their respective sections in this
manual.
