Clean filtered charge circuit oil exits the filter at the left hand fitting and flows to the pilot steering control and the steering pump. A combination S•O•S and fluid sampling port (K) is installed on the inlet side of the charge circuit filter base. The implement pump (16) is mounted to the lower left rear face of the torque converter housing. The Pilot Control Manifold (33) for the AccuGrade™ system is located below the bank 4 valve stack behind the right hand lower interior trim panel. Located inside the machine right fender outside compartment is the Hydraulic Pressure Remote Test Port panel. Machine system pressures can be checked and monitored here. The arrangement of the pressure ports on this panel are: - D Pilot Supply. - E Charge pump relief. - A Implement pump discharge. - SOS Oil Sampling. - Y2 Left steer pilot. - Y1 Right steer pilot. - MA Right steer loop. - MB Left steer loop. - B Implement pump signal.

Service points identi- fied above are: (HA) Implement pump discharge pressure test port. (14) Accumulator. (CP) Pilot supply pressure test port. (S•O•S) Hydraulic oil sampling port. (CPG) Accumulator pressure test port. The implement hydraulic pump (1) is mounted to the rear of the flywheel housing, at the upper left corner. High pressure supply oil to the implement valve stack is directed through a hose that connects to the pump discharge port (B). High pressure supply oil to the pressure reduc- ing manifold is directed through a hose that connects to the lower fitting (C) from the pump discharge port. A pump discharge pressure sensor (D) is installed on the opposite side of the "tee" fitting from the pressure reducing manifold supply line. This pressure sensor is only present on machines that are equipped with AccuGrade. It is a necessary component for the calibration of the four proportional solenoids on the EH pilot manifold that are used for blade control. Machines that are not equipped with AccuGrade will have an "L" fitting at this location, connecting the pump- supply line to the pressure reducing manifold. Other components identified above are: E. pump pressure and flow compensator valve F. fitting for the load sensing signal line (from the signal resolver network) G. fitting for the case drain line This implement pump is identical to the implement pump used in the D6R Series II machines with differential steering. The steering and implement control valve stack is mounted to a bracket inside the right fender, below the right console in the operator compartment. The implement valve stack consists of the inlet manifold (5), the steering valve (6), the blade lift control valve (7), the blade tilt control valve (8), the optional blade angle control valve (A), the ripper (or winch) control valve (9), and the end cover (10), EH pilot manifold for tilt and lift. The blade angle control valve and the ripper/winch control valve may not be present, depending on how the machine is equipped. 5 6 7 8 A 9 28 10 The AccuGrade Boost solenoid valve directs pilot supply oil to an external resolver. The blade lower solenoid controlled pilot valve also directs pilot supply oil to this same external resolver, in addition to the pilot supply oil that is directed to the LOWER end of the blade lift control valve. Pilot supply oil is directed (through the resolver) to the Float Pilot Boost line when either solenoid is ENERGIZED. The Float Pilot Boost signal line enters the signal resolver network through the end cover of the valve stack. In either situation, the pump's flow compensator valve senses the pilot supply oil as a signal and the implement pump will up stroketo maintain margin pressure above LOW PRESSURE STANDBY pressure. (If the steering valve or another implement valve sends a higher signal into the resolver network, the highest pressure is sensed by the compensa- tor valve.)This EH pilot manifold is only present on ARO machines. 15 14 Illustration (A) shows the EH pilot manifold when the operator has moved the thumb rocker switch to the BLADE ANGLE RIGHT position. The Machine ECM receives the signal from the thumb rocker switch and sends a corresponding signal to the ANGLE RIGHT solenoid controlled pilot valve and the solenoid is ENERGIZED. Pilot supply oil is then directed to the appropriate end of the blade angle control valve. EH PILOT MANIFOLDS PRESSURE MANIFOLD MACHINE COMPONENT LOCATIONS IMPLEMENT PUMP STEERING and IMPLEMENT CONTROL VALVE The EH pilot manifold (28) for blade lift and tilt functions is mounted to the outboard side of the valve stack bracket, if the machine is equipped with AccuGrade. Components of the AccuGrade EH pilot manifold identified above are the blade raise solenoid, the blade tilt right solenoid, the AccuGrade Boost solenoid, the blade tilt left solenoid, and the blade lower solenoid. The EH pilot manifold receives pilot supply oil from the pressure reducing manifold. The EH pilot manifold contains four (proportional) solenoid controlled pilot valves that receive PWM signals from the Machine ECM for operation of the blade lift and the blade tilt functions. When ENERGIZED, the solenoid controlled pilot valve directs pilot supply oil to the end of the corresponding implement control valve, in direct proportion to the movement of the dozer control lever (or as automatically commanded by the AccuGrade system). The EH pilot manifold also contains the AccuGrade Boost solenoid valve, which uses an ON/OFF solenoid.The AccuGrade Boost strategy was discussed earlier in the Implement Hydraulics section ofthis presentation.
