Left Side ViewSteering Components (10) Left steering cylinderThe primary steering system is made up of two basic circuits. The two basic circuits are the pilot circuit and the high-pressure circuit. When a machine is equipped with the secondary steering attachment, the steering system includes one additional circuit.Metering pump (1) is attached to the bottom of the steering column, and located under the floor of the cab. Neutralizer valves (2) and (4) are located on the front center section of the upper frame under the cab near the upper hitch.Steering control valve (6) is located on the right side of the machine under the cab platform. Hydraulic oil tank (15) is located behind the cab.Steering pump (13) is located under the cab on the right side of the machine. A pressure and flow compensator valve is attached to steering pump (13) .Pilot Circuit
The pilot circuit consists of the following components. Metering pump (1), neutralizer valve for a left turn (2), neutralizer valve for a right turn (4), selector spool (7),
