The steering axle is mounted to the rear of the frame. A
hydraulic cylinder actuates the steering (Figure 9F-1).
The steering cylinder is attached to the right hand arm

left hand steering arm using a tie rod and ball joints.
The right ball joint has right hand threads and the left
ball joint has left hand threads. The tie rod can be
turned to adjust the steering components.
