The implement control levers for the D10R are not mechanically connected to the dozer and ripper control valves. The blade control lever (1) and the ripper control lever (2) are input devices to an Electronic Control Module (ECM) located below the implement control levers. Moving the blade control lever forward or rearward LOWERS or RAISES the blade. Moving the lever left or right allows the blade to TILT LEFT or TILT RIGHT. The thumb lever (3) allows the operator to PITCH the blade forward or rearward. The left button (4) on the blade control handle allows the operator to activate the Automatic Mode and the right button (5) cancels the Automatic Mode, so that the blade may be controlled manually. Located on the front of the blade control handle is a trigger switch (not visible). When this switch is engaged, the blade will PITCH FORWARD to dump the blade load. The trigger switch performs the same function as the thumb lever when moved to the right. Ripper RAISE and LOWER positions are controlled by the thumb switch (6) at the front of the ripper control lever. The finger switch (7) allows the operator to control SHANK IN and SHANK OUT. Pushing the button (8) on the ripper control lever raises the ripper to maximum height or moves the ripper tip to the full SHANK IN position. Also located in this view are the throttle control switch (9) and the horn switch (10).

The ATAAC assembly is located in the hood above the engine. Hot air from the turbochargers flows in the aftercooler inlets (1). The hot air passes though the aftercooler and exits through the aftercooler outlets (2) and into the engine. A fan (not visible) on the inside of the ATAAC assembly is rotated by the hydraulic fan motor (3). The fan distributes air evenly over the heat exchangers (4) to cool the turbocharged air. Some of the hot air passing over the heat exchangers is vented to the outside air through air ducts at the top of the radiator housing as discussed on the previous page. NOTE: The fan motor is driven by oil supplied from the rear section of the implement hydraulic pump. The rear section of the implement pump also supplies oil to the implement pilot system.

POWER TRAIN Major changes to the D10R power train include a five-section pump and an updated Power Train Electronic Control System. The D10R is equipped with an Electronic Clutch Pressure Control (ECPC) transmission similar to the medium size track-type tractor transmissions. The ECPC transmission includes five proportional solenoid valves that are electronically modulated. Each solenoid valve directs oil to a single clutch in the transmission. In the current D10R, the transmission solenoids are ON/OFF solenoid valves and modulation is done hydraulically. The priority valve which is housed in the priority valve and lube management valve group is electronically controlled by the Power Train ECM. The priority valve allows transmission/torque converter charging section oil (A) to supplement transmission charging section oil (D) when the engine speed is below 1485 rpm, during a transmission shift, or when the power train oil is cold.

Shown is a sectional view of an ECPC transmission valve. The Power Train ECM controls transmission shifting by modulating the current to the ECPC solenoid valves, which varies the oil pressure to the clutches. Increasing the current forces the shaft to the right, which pushes the ball to the right and restricts the oil flow to drain. The reducing spool also moves to the right due to the pressure increase in the chamber at the left of the orifice. This movement allows more oil to flow from the supply passage, across the metering surfaces to the clutch. As the spool moves to the right, the ball reduces the rate of internal oil flow to drain.

Components visible at the rear of the torque converter include the torque converter outlet relief valve (1) and pressure tap (2). The power train oil temperature sensor (3) provides a signal to the VIDS ECM indicating power train oil temperature. The transmission input speed sensor (4) provides a signal to the Power Train ECM indicating transmission input (torque converter output) speed. NOTE: Transmission intermediate speed is measured at the No. 4 clutch with two intermediate speed sensors, and transmission output speed is measured at the transmission output shaft with two output speed sensors.

IMPLEMENT HYDRAULIC SYSTEM The D10R is equipped with an Electro-hydraulic Implement Control System similar to the D11R, which controls the hydraulic pilot valves for the blade and ripper. The Implement ECM receives input signals from the blade control lever position sensors, ripper control lever position sensors, and various other sensors and switches. The ECM sends corresponding output signals to energize the appropriate pilot solenoid valves on the electro-hydraulic manifold. The proportional solenoid valves control the amount of pilot oil that is sent to the dozer or ripper control valves to shift the appropriate spools and direct main pump oil to the head or rod end of the cylinders. The ECM also sends corresponding output signals to energize the pitch and single tilt ON/OFF solenoid valves on the dual tilt valve. The pitch and single tilt ON/OFF solenoid valves direct oil to shift the dual tilt valve, which determines blade tilt and pitch angles. The ECM controls the blade height, blade tilt, blade pitch, ripper height, and ripper shank in or out functions.

The implement hydraulic system for the D10R Track-type Tractor is a continuous flow design that permits minimum pressure in the system when the implement control valves are not activated. The oil flow for operation of the bulldozer and ripper is provided by two sections (tilt and lift) of the three-section implement gear pump. The third section of the implement pump supplies oil to the ATAAC fan motor and pilot oil for the implement system. The cooling oil for the hydraulic circuits is also provided by the ATAAC fan circuit.

27 The implement system for the D10R is operated by pilot oil. The fan pump supplies pilot oil to the electro-hydraulic pilot manifold, which includes an ON/OFF implement lockout solenoid valve that allows oil flow to the proportional solenoid valves or blocks oil flow to the solenoid valves. The accumulator provides pilot oil for lowering the blade with a dead engine. The four proportional solenoid valves control the amount of pilot oil directed to the dozer control valve. This pilot oil is sent to the ends of the tilt or lift spool and control BLADE LIFT, BLADE LOWER and FLOAT, BLADE TILT LEFT, and BLADE TILT RIGHT. If the tractor is equipped with a ripper, the pilot manifold is equipped with two additional bolt-on blocks. These blocks also contain four proportional solenoid valves that direct pilot oil to the ripper control valve to select RIPPER RAISE, RIPPER LOWER, SHANK IN, and SHANK OUT. The ripper proportional solenoid valves control the amount of pilot oil directed to the ripper control valve. The electro-hydraulic pilot manifold also includes two pressure reducing valves and a shuttle valve. One pressure reducing valve regulates the pilot supply oil pressure and the other pressure reducing valve regulates the resolved oil pressure from the logic valve. The shuttle valve directs the highest oil pressure (pilot supply oil or resolved logic valve oil) to the proportional solenoid valves.
