The Power Steering Gear Box with OEM number 3401000LD010 is a direct-fit replacement hydraulic steering gear for JAC N56 light trucks. This component converts the rotary motion of the steering wheel into the linear motion that turns the front wheels, while providing hydraulic assistance to reduce driver effort.
Working Principle: The steering gear box receives hydraulic pressure from the power steering pump. When the driver turns the steering wheel, the input shaft actuates a rotary valve that directs hydraulic fluid to the appropriate side of the internal piston. The piston moves the sector shaft, which is connected to the steering linkage, turning the wheels. A worn or leaking gear box causes steering play, heavy steering effort, and fluid loss.
