TM 9-2320-360-34-1
1-16. STEERING SYSTEM
The steering system uses two steering axles, one at the front (1) and one at the rear (2). Each axle turns in response to
turning the steering wheel (3) in the cab.
Steering power is generated by a steering pump (4) driven directly at the engine providing pressure to two steering gears
(5), one at each steering axle. The pump delivers hydraulic fluid to enable the operator to turn the wheels of a fully-loaded
truck. An interconnected series of shaft linkages rotate with hydraulic power assist to turn the two axles.
As the steering wheel is turned, the rotational motion of the upper steering assembly shafts (6) is translated at a tee gear
box (7) below the cab to both the front and rear power steering gears (5). The gear boxes multiply the rotational force to a
pair of drag links (8) and axle steering arms that apply directional motion to turn the axles.
In the event a steering line (9) to a steering axle is severed or fluid leaks from the system (power steering inoperable), the
truck can be steered for short distances in emergency situations.
