Illustration 2 g01072654
Hydraulic implement pump (1) is a pressure compensated piston pump with variable displacement. The pump provides the oil flow for the implement hydraulic system. Oil is pumped from the hydraulic tank and to the control valves. The oil is then available to activate the implements when the operator moves the implement control levers.A compensator valve is attached to the hydraulic pump. The compensator valve regulates pump output flow in response to the demands of the system. This valve also limits the maximum system pressure.The hydraulic pump is mounted to the lower left portion of the torque converter housing.Implement Control Levers

Bulldozer control lever (8) controls lifting and tilting of the blade. The bulldozer control lever also controls the angle of the blade. Ripper control lever (9) is located behind the bulldozer control lever. The ripper control lever controls the lift operation of the ripper, if the machine is equipped with a ripper. The control levers are connected to the control valves by linkages.Implement Control Valve
