6A.1 GENERAL DESCRIPTION
The steering system consists primarily of a steering wheel, an orbitrol, and a power cylinder.
When the steering wheel is turned, the rotation is transmitted to the orbitrol; the oil passages in the
orbitrol are changed over to direct the hydraulic pressure from the flow divider valve to the power
cylinder, which extends or contracts depending on the hydraulic pressure, thereby steering the
truck.
