Hydraulic Operation
The main components of the steering system are the priority
valve 7, load sensing steer unit 42, hydraulic tank T and the
front power track rod ram 10.
When the steering wheel is turned, a pressure demand is
sensed at the priority valve 7 via load sensing line LS.
Oil from the hydraulic pump P2 is then distributed via the
priority valve to the steer unit 42, which then directs the oil
to the front power track rod ram 10 untill the required
steering lock is achieved.
When the steering lock is held, the pressure signal LS
ceases, flow from the hydraulic pump P2 is now distributed
to the main hydraulic circuit via the priority valve 7.
Maximum steering system pressure is controlled by a relief
valve located in the steering unit 42.
