Front of Engine Compartment (1) Drum offset manifold (2) Offset left solenoid (3) Offset right solenoidDrum offset manifold (1) is located at the front of the engine compartment. This manifold contains two solenoids: offset left solenoid (2) and offset right solenoid (3). The ECM controls these solenoids. The manifold also contains a priority valve, a flow control valve, two pilot opened check valves, and a relief valve. The steering and charge pump provides the flow to port "P" of drum offset manifold (1). The flow control valve in the offset manifold is adjustable and set to provide a flow rate of 10 L/min (2.6 US gpm) to the drum offset cylinder. The pilot opened check valves are located in the lines to the head and rod ends of the drum offset cylinder. The line to the head end of the cylinder is connected to port "A1" of the manifold, and the line to the rod end of the cylinder is connected to port "B1" of the manifold. The relief valve limits the maximum pressure available to the drum offset cylinder to 15000 1500 kPa (2180 218 psi).Drum offset pressure can be measured at the pressure tap in port "X" on the bottom face of drum offset manifold (1).
