THEORY OF OPERATION - CONTINUED
The power steering system consists of an integral steering gear (which includes a manual
steering mechanism and hydraulic control valve), hydraulic hoses, power steering pump,
reservoir, and other components.
The power steering pump, driven by the engine, provides the power-assist for the steering
TRACTION CONTROL SYSTEM
The inter-axle differential lock is controlled by the air operated lever labeled INTER-AXLE
DIFFERENTIAL on the drivers instrument panel. Under normal driving conditions, the con-
trol lever should be in the UNLOCKED position. During poor driving conditions the control
lever may be moved to the LOCKED position to improve traction. When the inter-axle differen-
tial lock is applied the drive shaft becomes a solid connection between the two rear axles.
