Hydraulic Steering Gear Assembly

The steering system is composed of a fully hydraulic
steering gear and steering cylinder. See Figure 19
Item 2. The hydraulic steering gear transfers high
pressure hydraulic fluid from the bypass valve to the
steering cylinder. When engine is turned off, the pump
cannot feed hydraulic fluid, and steering may be
performed manually.
The steering column and steering wheel are designed
to tilt 4.5º forward and backward, for operator comfort.
See Figure 19 Item 1.
