The main components of the steering system are the priority valve in main pump, load sensing steer unit, hydraulic tank and front power track rod ram.
When the steering wheel is turned, a pressure demand is sensed at the priority valve in main pump via load sensing line LS.
Oil from the main pump is then distributed via the priority valve to the steer unit, which then directs the oil to the front power track rod ram until the required steering lock is achieved.
When the steering lock is held, the pressure signal LS ceases, flow from the main pump is now distributed to the main hydraulic circuit via the priority valve in main pump.
Maximum steering system pressure is controlled by a relief valve located in the steering unit.
