(5) Steering System (figure 22).
Power is supplied to the main
steering gear (1) by an engine-driven pump (2). The fluid reservoir
(3) is shared with the main hydraulic system. The steering wheel (4)
is mechanically linked to the main steering gear.
Steering wheel
motion is hydraulically transmitted to a piston in the slave gear (5)
causing it to follow the rotation of the main gear.
The main gear
pitman arm (6) is mechanically connected to the slave gear pitman arm
(7). These pitman arms move the steering mechanism on the front axles
(8) left or right, causing the vehicle to steer left or right.
