POWER STEERING, GENERAL
The VN power steering consists of an integrated gear. The VHD
vehicle has both the integrated gear and the hydraulic power cylinder.
There is also a power steering pump with fluid container. The pump,
driven by the engine, provides hydraulic pressure to the power
steering. If the engine is not working, the steering is only manual. With
the power steering not working, the effort required to turn the steering
wheel is much greater than with power assist. If the power steering
assist fails, bring the vehicle to a safe stop. DO NOT drive the vehicle
until correcting the cause of the problem.
While operating the vehicle, avoid ruts and obstructions which cause
binding condition on the sides of the front wheels. Drive the vehicle out
of the rut, then turn the steering wheel. If possible, avoid turning the
wheels while the vehicle is at a standstill as this places a considerable
load on the power steering system and front axle.
Periodically check the power steering fluid reservoir and keep it filled to
the proper level with the recommended fluid. See the Operator’s
Manual Vehicle Maintenance for more information.
