Fluid Sample Volume (approximate)

75 mL 2.5 oz

TX1024519A —UN—01JUN07

This is the recommended procedure for obtaining oil samples using the John Deere sampling valve. A cap probe, plastic bag, and oil sampling kit for the appropriate system are needed for this procedure. Part numbers for the required items can be found at the end of this procedure. Fluid systems should be sampled at the following intervals:

• Each system at every oil change prior to changing oil • Engine oil: 250 hours • Engine coolant: 500 hours • Hydraulic oil: 500 hours • Transmission oil: 500 hours • Power train (axles, gearboxes): 500 hours

System Fluid Purge (excavator shown)

Machine Preparation 1. Start the machine and warm system to normal operating temperature. Operate machine functions so that the fluid is agitated throughout the system. 2. Once the system has reached operating temperature, operate engine at slow idle. Specification Engine—Speed..........................................................................Slow Idle

Specification System Fluid Purge—Volume (approximate)............................................................................... 100 mL 3.4 oz

3. Properly dispose of collected waste fluid. 4. If oil flow needs to be increased to obtain a representative sample, accelerate the flow of the system by increasing the engine speed to high idle while taking the sample.

3. Locate sample valve on unit and clean the area around the valve prior to removing dust cap. This will reduce additional fluid sample contamination. See Fluid Sampling Test Ports—If Equipped. (Operator's Manual.) 4.

Once the area has been cleaned, remove the dust cap from the valve.

Priming Sample Valve Oil must be purged from the system to ensure a representative sample is collected in the test collection bottle. The appropriate amount of waste oil is determined by the distance of the sampling valve from the flow of the system. It is recommended one full sample bottle, equal to 100 mL (3.4 oz), be purged from a remotely mounted valve prior to collecting the sample. 1. Connect probe to sample valve by placing the probe end into the valve port. 2. Press and hold the probe to release an appropriate amount of fluid into a waste container. Continued on next page

System Information 1— Continuity Chart 4— Wire Identification 2— Wire Bundle 5— Wire Splice 3— Routing Location Information 6— Coordinate Letter

7— Coordinate Number 8— Component Name 9— Component Identification Number

The System Functional Schematic is made up of sections which contain one harness. The harnesses are separated by dashed lines and are laid out to match their relative position on the machine. Components can easily be found by using the coordinate system. The coordinate letter (6) is located on the left and right sides of the schematic while the coordinate number (7) is located on the top and bottom. Each electrical component is shown by a schematic symbol (10), the component name (8), and a component identification number (9). A component identification number and name will remain the same throughout the Operation and Test Technical Manual. This will allow for easy cross-referencing of all electrical drawings (Schematics, Wiring Diagrams, and Component Location). A continuity chart (1) is included for each multi-terminal switch.

When two or more wires converge to form a single dark line, it is a wire bundle (2). A wire bundle represents a group of wires that can be easily followed but are not joined together. Routing location information (3) is presented to let the reader know when a wire is connected to a component in another section. TO and FROM statements identify when power is going “To” or coming “From” a component in a different location. Both the coordinate letter and number will be called out separated by a colon. The component number and pin number are given at the bottom of the statement. In the example, power is coming from component X3 ECU connector 3, in coordinate B:27. A wire splice (5) is represented by two or more wires connected by a dot.

System Information 1— Component Identification Number 2— Connector 3— Connector Face View

4— Wire Harness 5— Wire Number 6— Wire Splice 7— Wire End #1 Termination Location

Each harness on the machine is drawn showing connectors, wires, and splices. A “W” component identification number identifies harnesses. (W6, etc.) The harness is drawn showing spatial arrangement of components and branches. A component identification or connector number (1) identifies each component. The wire harness (4) is terminated by a top or side view of the connector (2). If more than one wire is supplied to the connector, a harness side connector face view (3) is provided. Each wire number is labeled for the appropriate pin. If only one wire is supplied to the connector, the wire number (5) is indicated. An “X” component identification number of 100 or higher identifies splices (6). Each splice lists side A wires and side B wires to differentiate the side of the harness that the wires come from.

8— Wire Number 9— Wire Color 10— Wire End #2 Termination Location

A wire legend is provided for each harness. A component identification number is listed in the “END #1” column (7) to indicate the termination location of one end of a wire. In the center, the wire number (8) and wire color (9) are listed. A component identification number in the “END #2” column (10) identifies the opposite end of the wire. Component Location Diagram The Component Location Diagram is a pictorial view by harness showing location of all electrical components, connectors, harness main ground locations and harness band and clamp location. Each component will be identified by the same identification letter/number and description used in the System Functional Schematic Diagram. KK70125,00005B4 -19-16FEB11-5/4

Starting Circuit—Unswitched power is supplied to the following components:

• Key Switch (S1) • Starter Motor (M1) • Start Relay (K1) When the park lock lever is in the LOCK (up) position, park lock lever switch (S20) will provide ground to pin C2 (coil) of start relay (K1). NOTE: The park lock lever switch also provides signals to the transmission control unit for park brake control. For information on park brake control, see Transmission Control Unit (TCU) Circuit Theory of Operation. (Group 9015-15.) When key switch (S1) is turned to the START position, current from the key switch terminal ST flows through start relay 10A fuse (F21) to pin C1 (coil) of the start relay, energizing the relay. With the start relay energized, current flows to the starter motor solenoid, engaging the starter motor. The start relay diode (V2) protects the start circuit from voltage spikes when the start relay de-energizes. As the starter motor cranks the engine, the crankshaft position sensor (B6) sends a signal representing engine rpm to the engine control unit (ECU) (A3). When the ECU detects this signal, it knows the crankshaft is turning. The ECU then sends a signal to the fuel pump control valve solenoid (Y1) to provide high-pressure fuel to the electronic fuel injectors. At the same time, the ECU sends a predetermined amount of current to the electronic fuel injectors to start the fuel injection process and, thus, start the engine. For more information on the ECU, pump control solenoid, and electronic fuel injectors, see Engine Control Unit (ECU) Circuit Theory of Operation. (Group 9015-15.) Charging Circuit—Alternator (G3) provides power to all machine circuits and charges the batteries when the engine is running. Terminal B+ of the alternator is connected to battery positive (+) at all times. When key switch (S1) is in the ON position, current flows through start aid/alternator excitation 10A fuse (F25) and alternator excitation 5A diode (V1) to the D+ terminal of the alternator. The current then flows through the alternator field windings, causing excitation of the windings. Alternator excitation diode (V1) prevents current feedback from the alternator if the alternator circuitry is improperly connected or if there is a major malfunction. See Alternator Test for more information. (Group 9015-20.) AA95137,000120C -19-27APR10-2/2

This machine utilizes a controller area network (CAN) on which the following electronic control devices communicate.

• Transmission Control Unit (TCU) • Engine Control Unit (ECU) • Standard Display Monitor (SDM) • JDLink™ Machine Information Gateway (MIG) (if equipped) (S.N. —196417) • JDLink™ Modular Telematics Gateway (MTG) (A6000) Control Unit (S.N. 196418— ) Operations and functions of the individual devices on CAN 1 are covered separately.

• See Engine Control Unit (ECU) Circuit Theory of Operation. (Group 9015-15.) • See Transmission Control Unit (TCU) Circuit Theory of Operation. (Group 9015-15.) • See Standard Display Monitor (SDM) Circuit Theory of Operation. (Group 9015-15.) • For the JDLink™ MIG (S.N. —196417), see General Information in JDLink™ / ZXLink™ Machine Monitoring System. (CTM10006.) • For the JDLink™ MTG (S.N. 196418— ), see General Information in JDLink™ (MTG) Diagnosis and Test Manual. (TM114519.) The devices on the CAN are communicating at a high frequency, which makes the network susceptible to interference caused by many electrical sources. The devices on the CAN are connected via three wires woven together called a twisted triple. The twisted triple consists of a high-voltage signal wire, a low-voltage signal wire, and a ground wire. This method reduces interference and helps the devices communicate with minimal errors. There are a few more components connected to the CAN. The CAN termination resistors (R4 and R5) are 120-ohm resistors, which are connected on opposite ends of the bus to avoid signal errors. The Service ADVISOR™ connector (X3) is provided for machine diagnostic purposes. For connection information, see Service ADVISOR™ Connection Procedure. (Group 9015-20.)

Engine Control Unit (ECU) (A3)— For component location, see Engine Harness (W6) Component Location. (Group 9015-10.) The ECU uses information received from various sensors to determine the correct amount of fuel and injection timing based on load, temperatures, and operator input. Some of the data calculated by the ECU is transmitted across the CAN data line to other controllers. For more information concerning the CAN data line, see Controller Area Network (CAN) Circuit Theory of Operation. (Group 9015-15.) The ECU also detects malfunctions in the sensors and sensor circuits, or abnormal operating conditions. When this happens, the ECU will generate a diagnostic trouble code (DTC). See Engine Control Unit (ECU) Diagnostic Trouble Codes. (Group 9001-20.)

The ECU contains a barometric air pressure (BAP) sensor that is located inside the ECU. This sensor is used to determine the pressure of the ambient air at the mounting location of the ECU. The BAP sensor helps the ECU determine the air density for calculating the correct air/fuel ratio. This sensor cannot be repaired or replaced without replacing the entire ECU. The ECU also contains a temperature sensor that is located inside the ECU. This sensor is used to determine the internal temperature of the ECU. If the ECU temperature exceeds specification, the ECU will limit the speed of the engine in an attempt to protect the ECU from permanent damage. This sensor cannot be repaired or replaced without replacing the entire ECU. Ground is provided at pins L2, L3, and M2 of ECU connector X26. Unswitched battery power is available at pins L1, L4, M1, and M4 of ECU connector X26, through fuse (F7).

Warmup Indicator (H4)— For component location, see Main Cab/Canopy Harness (W5) Component Location. (Group 9015-10.)

When key switch (S1) is turned to the ON or START position, power is available at the anode of warmup indicator (H4), through fuse (F24). When the transmission oil temperature is below 0°C (32°F), the ECU will provide a ground to the cathode of the warmup indicator, causing the indicator to come on. During that time, the ECU limits the engine speed to 900 rpm in neutral and 1200 rpm in forward and reverse. The transmission control unit (TCU) also limits the transmission speed to 1.7 during the time the warmup indicator is lit. The transmission oil temperature is monitored by the standard display monitor (SDM) (H1), which transmits this information across the CAN data line to the ECU.

• For more information on the warmup indicator, see

Whenever an engine DTC occurs, the information is captured or recorded. The information generated is called a Snapshot. The Snapshot information is categorized in two types; Snapshot Capture and Snapshot Recording. For more information, see Snapshot Instructions. (CTM502.)

When key switch (S1) is turned to the ON or START position, current from fuse (F24) flows to pin B2 of ECU connector X26, causing the ECU to power up.

Fuel Rail Pressure Sensor (B10)— For component location, see Engine Harness (W6) Component Location. (Group 9015-10.) The ECU supplies a 5-volt reference voltage and ground to the fuel rail pressure sensor at pins E2 and D3 of ECU connector X27. The fuel rail pressure sensor sends an analog signal representing fuel rail pressure to pin E3 of ECU connector X27. The ECU uses this signal to monitor the high pressure side of the fuel system and apply derate conditions when needed. If the ECU senses a value that is out of valid range, the ECU will derate fuel delivery by 50%. The fuel delivery will recover to full power when the problem is corrected.

Sub-System Diagnostics pressure, the ECU will derate the engine fuel delivery. For information on engine deration, see OEM Engines Derate Specifications. (CTM502.)

The ECU senses resistance from the engine coolant temperature sensor at pins D2 and C4 of ECU connector X27. The ECU transmits the engine coolant temperature information across the CAN data line to the SDM. The SDM uses this information to determine the position of the needle on the engine coolant temperature gauge and moves the needle accordingly. It also activates a warning indicator when coolant temperature becomes too high. See Instrument Panel Functions. (Operator's Manual.) The engine coolant temperature can also be displayed in the SDM service menu as a live value. See Standard Display Monitor (SDM) Menu Structure—Service Mode. (Group 9015-20.) The ECU uses the signal from the engine coolant temperature sensor to monitor the coolant temperature and apply derate conditions when needed. If the engine coolant temperature reaches 111°C (232°F), the ECU will derate fuel by 80% of full power. If the coolant temperature reaches 115°C (239°F), the ECU will derate fuel by 40% of full power. The fuel delivery will recover to full power when the engine coolant temperature drops below the derate threshold temperature. If the ECU senses a value that is out of valid range, the ECU will use the default temperature of 90°C (194°F). High ECT engine protection is disabled. For information on engine deration, see OEM Engines - Derate Specifications. (CTM502.) For information on how temperature sensors operate, see Measuring Temperature. (CTM502.)

For information on how pressure sensors operate, see Measuring Pressure. (CTM502.) For sensor specifications, see Electrical Component Specifications. (Group 9015-20.) Water In Fuel (WIF) Sensor (B60)— For component location, see Engine Harness (W6) Component Location, or Transmission Harness (W7) Component Location. (Group 9015-10.) The WIF sensor measures the amount of resistance of the fluid in the water separator bowl. Since water is a better conductor of electricity than fuel, and, if water is present in the separator bowl, the ECU senses a resistance drop between pins B2 and D2 of ECU connector X27. If the ECU senses low resistance indicating water in fuel, the ECU will derate fuel delivery by 50% of full power. The fuel delivery will recover to full power when the problem is corrected. For information on engine deration, see OEM Engines - Derate Specifications. (CTM502.) For sensor specifications, see Electrical Component Specifications. (Group 9015-20.)

For sensor specifications, see Electrical Component Specifications. (Group 9015-20.) Engine Oil Pressure Sensor (B14)— For component location, see Engine Harness (W6) Component Location. (Group 9015-10.) The ECU supplies a 5-volt reference voltage and ground to the engine oil pressure sensor at pins F3 and D2 of ECU connector X27. The engine oil pressure sensor sends an analog signal representing engine oil pressure to pin A3 of ECU connector X27. The ECU transmits the engine oil pressure information across the CAN data line to the SDM. The SDM uses this information to determine position of the needle on the engine oil pressure gauge and moves the needle accordingly. It also activates a warning indicator when oil pressure is too low. See Instrument Panel Functions. (Operator's Manual.) The engine oil pressure can also be displayed in the SDM service menu as a live value. See Standard Display Monitor (SDM) Menu Structure—Service Mode. (Group 9015-16.) The ECU uses the engine oil pressure sensor to monitor the oil pressure and apply derate conditions when needed. If the oil pressure is below threshold

If the ECU senses a value that is out of valid range, the ECU will use the default pressure of 500 kPa (5 bar) (72.5 psi). Low oil pressure engine protection is disabled.

The ECU senses resistance from the fuel temperature sensor at pins D2 and F4 of ECU connector X27. The ECU transmits the fuel temperature information across the CAN data line to the SDM so it can be displayed in the SDM service menu as a live value. See Standard Display Monitor (SDM) Menu Structure—Service Mode. (Group 9015-16.) The ECU uses the signal from the fuel temperature sensor to monitor the fuel temperature and apply derate conditions when needed. If the ECU senses fuel temperature above 100°C (220°F), the ECU will derate the fuel delivery by 80% of full power. The fuel delivery will recover to full power when the fuel temperature drops below the derate threshold temperature. If the ECU senses a value that is out of valid range, the ECU will use the default temperature of 40°C (104°F). High fuel temperature engine protection is disabled. For information on engine deration, see OEM Engines - Derate Specifications. (CTM502.) For information on how temperature sensors operate, see Measuring Temperature. (CTM502.)

Manifold Air Temperature (MAT) Sensor (B31)—The ECU senses resistance from the MAT sensor at pins C2 and D2 of ECU connector X27. The ECU transmits the MAT sensor information across the CAN data line to the SDM where it can be displayed in the SDM service menu as a live value. See Standard Display Monitor (SDM) Menu Structure—Service Mode. (Group 9015-16.) The manifold air temperature can cause an engine fuel derate condition if it reaches 88°C (190°F). The ECU will derate fuel 2% per minute up to 20%. If the manifold air temperature falls below the derate temperature, the ECU will recovery fuel delivery 2% per minute until power is fully restored.

(Group 9015-10.) The ECU detects the signal from the crankshaft position sensor at pins B4 and D4 of ECU connector X27. The ECU uses this signal to determine when the number one cylinder is at top dead center. The ECU also uses this signal to calculate engine (crankshaft) speed and sends this information across the CAN data line to the SDM, where it appears in the monitor display window as engine rpm. The crankshaft speed can also be displayed in the SDM service menu as a live value. See Standard Display Monitor (SDM) Menu Structure—Service Mode. (Group 9015-20.)

(Group 9015-10.) The pump control valve regulates delivery of fuel to the high-pressure common rail (HPCR). ECU sends a signal out pins H1 and H2 of ECU connector X27 to the fuel pump control valve solenoid. When the solenoid is energized, fuel is allowed to discharge from the fuel outlet on the high-pressure fuel pump to the HPCR. For more information, see High Pressure Fuel Pump Operation. (CTM502.) For more information on the high-pressure common rail (HCPR), see High Pressure Common Rail (HPCR) Operation. (CTM502.)

Standard Display Monitor (SDM) (H1)— The SDM receives unswitched battery power from the ECU/SDM 10A fuse (F7) at pin A of SDM connector X6. System ground is available at pin P of SDM connector X6. When the key switch is turned to the IGN or ST position, current flows to the coil of TCU/SDM relay (K4), energizing the relay. Current flows across the contacts of TCU/SDM relay, through SDM switched power 5A fuse (F23), to terminal L of SDM connector X6, powering up the SDM. When powered-up, the SDM performs a self-test by activating all indicators: lights, gauges, and the monitor display window. For more information on SDM, see Instrument Panel Functions. (Operator's Manual.) The SDM contains a menu structure designed for monitoring certain machine functions for operational and/or diagnostic purposes. It provides a means for viewing and clearing diagnostic trouble codes (DTC) and also provides a means for adjusting certain machine and monitor settings. For more information on the SDM menu structure, see Standard Display Monitor (SDM) Menu Structure—Service Mode. (Group 9015-16.) The SDM uses the controller area network (CAN) data line to communicate with the engine and transmission controllers. For more information on the CAN, see Controller Area Network (CAN) Circuit Theory of Operation. (Group 9015-15.)

The transmission control unit (TCU) (A1) transmits travel speed, charge oil pressure, TCU diagnostic trouble codes, and other transmission related information across the CAN data line. This information can be displayed on the monitor display window. Most TCU related information must be accessed using the SDM menus. To access the SDM menus, see Standard Display Monitor (SDM) Menu Structure—Service Mode. (Group 9015-16.) The following electrical components are hard wired directly to the SDM:

• Transmission Oil Filter Restriction Switch (B15) • Hydraulic Oil Filter Restriction Switch (B16) • Air Filter Restriction Switch (B18) • Hydraulic Oil Temperature Sensor (B25) • Fuel Level Sensor (B35) • Transmission Oil Temperature Sensor (B40) • Monitor Alarm (H5) Transmission Oil Filter Restriction Switch (B15)— is a normally open switch that closes when the transmission oil filter becomes restricted. When this happens, ground is applied to pin J of SDM connector X5, causing the transmission oil filter restriction light to come on. For component location, see Transmission Harness (W7) Component Location. (Group 9015-10.)

The engine control unit (ECU) (A3) transmits engine speed, engine coolant temperature, engine oil pressure, and any ECU related diagnostic trouble code (DTC) information across the CAN data line. The SDM receives the engine coolant temperature and engine oil pressure information and uses this information to determine the needle position of the corresponding gauge. Engine speed and diagnostic trouble codes can be displayed on the monitor display window. The ECU and SDM also exchange machine model information to prevent an ECU mismatch. Once an ECU or SDM is installed in a machine, the unit cannot be removed and put in a different model machine. For more information on the ECU, see Engine Control Unit (ECU) Circuit Theory of Operation. (Group 9015-15.)

Sub-System Diagnostics

Hydraulic Oil Temperature Sensor (B25)— provides the SDM with a variable resistance based on hydraulic oil temperature. The SDM senses resistance at pin K and B of SDM connector X5. When the hydraulic oil temperature reaches a specified set point, the SDM will cause the STOP warning light and the hydraulic temperature warning light to come on: Specification Hydraulic Oil Temperature Warning Set Point—Temperature................................................................ 113° C 235° F

For more information on the hydraulic oil temperature sensor, see Electrical Component Specifications. (Group 9015-20.) Fuel Level Sensor (B35)— is a resistive (rheostat) type sensor attached to a float arm. The changing fuel level causes the float arm to move up and down relative to the fuel level. The float arm moves the wiper in the rheostat causing resistance to change relative to the movement of the float arm. This resistance is sensed by the SDM at pin N of SDM connector X6 and pin B of SDM connector X5. The SDM uses this information to determine the position of the needle on the fuel gauge and moves the needle accordingly. For component location, see Transmission Harness (W7) Component Location. (Group 9015-10.)

For fuel lever sensor specifications, see Electrical Component Specifications. (Group 9015-20.) Transmission Oil Temperature Sensor (B40)— provides the SDM with a variable resistance based on transmission oil temperature. The SDM senses resistance at pins A and B of SDM connector X5. When the transmission oil temperature reaches a specified set point, the SDM will cause the STOP warning light and the transmission temperature warning light to come on: Specification Transmission Oil Temperature Warning Set Point—Temperature.................................................................. 96° C 205° F

The transmission control unit (TCU) (A1) receives information from various sensors, mostly commands from the operator, and uses this information to control travel direction, travel speed, engine speed, and steering. The TCU transmits some of this information across the CAN data line for use by the engine control unit (ECU) and the standard display monitor (SDM).

• For more information on the ECU, see Engine Control Unit (ECU) Circuit Theory of Operation. (Group 9015-15.) • For more information on the SDM, see Standard Display Monitor (SDM) Circuit Theory of Operation. (Group 9015-15.) • For more information on the CAN data line, see Controller Area Network (CAN) Circuit Theory of Operation. (Group 9015-15.) For location of transmission electrical components: • See Main Cab/Canopy Harness (W5) Component Location. (Group 9015-10.) • See Engine Harness (W6) Component Location. (Group 9015-10.) • See Transmission Harness (W7) Component Location. (Group 9015-10.) The TCU transmits any TCU diagnostic trouble codes (DTC) that may occur across the CAN data line to the SDM. The TCU diagnostic trouble codes, transmission settings, and other diagnostic information can be accessed using the SDM menu structure. For more information, see Standard Display Monitor (SDM) Menu Structure—Service Mode. (Group 9015-16.) When the engine is started, the TCU will keep the transmission in neutral, regardless of the position of the transmission control lever (TCL). If the transmission control lever is not in neutral during start-up, the TCU requires the transmission control lever to be moved first to neutral position, then to forward or reverse position before travel can be obtained. The TCU does this by monitoring the status of neutral switch (S3). Also, if the park lock lever is moved to the UNLOCK (down) position while the TCL is in either forward or reverse position, it will be necessary to return the TCL to neutral, then back to forward or reverse before the TCU allows machine movement. Neutral Switch (S3)—The neutral switch is located in the transmission control lever. The TCU knows the position of the TCL by monitoring the status of the neutral switch. When the TCL is in the neutral position, the neutral switch is closed and provides a ground to pin E2 of TCU connector X2. Moving the TCL out of neutral removes the ground from pin E2. If the neutral switch causes a DTC, the forward and reverse functions will be disabled. Park Lock Lever Switch (S20)—When the park lock lever is in the LOCK (up) position, the park lock lever switch provides a ground to pin B3 of TCU connector X2. With the park lock lever at this position, the TCU will not allow an output to the park brake solenoid (Y11). Park brake solenoid is de-energized. When the park lock lever is in the UNLOCK (down) position, the park lock lever switch provides a ground to pin E2 of TCU connector X1. With the park lock lever at this position, the TCU energizes the park brake solenoid. The park lock lever switch also provides an interlock for the starting circuit. When park lock lever is in the LOCK (up) position, the park lock lever switch provides a ground to the coil of the start relay. For more information on the starting circuit, see Starting and Charging Circuit Theory of Operation. (Group 9015-15.) Park Brake Solenoid (Y11)—The park brake solenoid controls the charge pressure which releases the park brake. When the engine is running and the park lock lever is moved to the UNLOCK (down) position, and as long as the decelerator pedal is not fully pushed to the pedal stop, the TCU will send current out pin E3 of TCU connector X2 to the park brake solenoid, energizing the solenoid. With the park brake solenoid energized, charge pressure oil is allowed to flow to the park brake, releasing the park brake. For more information on the park brake, see Park Brake Operation. (Group 9026-05.) If the park brake solenoid circuit causes a DTC, the forward and reverse functions will be disabled. The park brake solenoid will de-energize if the engine stops, the park lock lever is moved to the LOCK (up) position, or if the decelerator pedal is pushed fully to the pedal stop. Decelerator Mode Switch (S8)—The decelerator mode switch allows the operator the option of using the decelerator pedal to control engine speed or transmission speed. When the switch is pushed to transmission mode, the decelerator mode switch provides a ground to the pin C1 of TCU connector X2. When the TCU detects this ground, it decelerates the transmission only when the decelerator pedal is pushed. When the switch is pushed to the engine mode, the ground is removed from pin C1. The decelerator pedal now controls engine speed. TCL Sensor (B2)—The TCL sensor is a rotary sensor located on a rotating shaft within the TCL assembly. The TCL sensor receives 5-volt power from pin A1 of TCU connector X1 and a ground reference from pin A3 of TCU connector X1. When the TCL is moved into forward and reverse positions, the rotating shaft turns a keyed slot on the sensor, which changes the resistance measured by the TCU at pin A2 of connector X1. When the TCL is put at certain positions during TCU calibration, the resistance measured at those positions is stored in the TCU memory. If the TCL sensor causes a DTC, the forward and reverse functions will be disabled. Steer Sensor (B5)—The steer sensor is a rotary sensor located on a rotating shaft within the TCL assembly. The steer sensor receives 5-volt power from pin D1 of TCU connector X1 and a ground reference from pin D3 of TCU connector X1. When the TCL is moved to left and right positions, the rotating shaft turns a keyed slot on the sensor, which changes the resistance measured by the TCU at pin D2 of connector X1. When the TCL is put at certain positions during TCU calibration, the resistance measured at those positions is stored in the TCU memory. If this sensor causes a DTC, the steer functions will be disabled and the maximum machine speed will be limited to 5.23 km/h (3.25 mph). Decelerator Sensor (B1)—The decelerator sensor is a rotary sensor located on a rotating shaft on the decelerator pedal. The decelerator sensor receives 5-volt power from pin F1 of TCU connector X1 and a ground reference from pin F3 of TCU connector X1. When the decelerator pedal is pushed down, the rotating shaft turns a keyed slot on the sensor, which changes the resistance measured by the TCU at pin F2 of connector X1. When the decelerator pedal is put at certain positions during TCU calibration, the resistance measured at those positions (including brake positions) is stored in the TCU memory.

Sub-System Diagnostics If this sensor causes a DTC, the maximum machine speed will be limited to creep. If this sensor causes a calibration code, the TCU default values will be used for this sensor. Transmission Speed Control Sensor (B4)—The transmission speed control sensor is used by the operator to control ground speed. The transmission speed control sensor receives 5-volt power from pin C1 of TCU connector X1 and a ground reference from pin C3 of TCU connector X1. When neither UP or DOWN buttons are pushed, the transmission speed control sensor sends approximately 2.20 volts to pin C2 of TCU connector X1. When the UP button is pushed, approximately 0.9 volts is sent to pin C2 of TCU connector X1. When the DOWN button is pushed, approximately 3.0 volts is sent to pin C2 of TCU connector X1. The values of the up, down, and null voltages are stored in the TCU during calibration. When either the UP or DOWN buttons are pushed, the TCU transmits the transmission speed across the CAN data line to the SDM. The SDM displays the transmission speed in the monitor display window. If this sensor causes a DTC, the maximum machine speed will be limited to 5.23 km/h (3.25 mph). Pump Pressure Control Pilot (PCP) (B8 and B9)—The rear and front PCPs control the displacement of the rear and front hydrostatic pumps, respectively. When the TCU receives a signal from any one of the operator controlled input sensors, the TCU applies positive or negative voltage to the PCPs, which causes electromagnetic valves to move accordingly. Movement of the electromagnetic valves creates differential control pressures, which varies the pump displacement and thus controls machine movement. For forward movement, the TCU will increase positive voltage (i.e. +3.5 V to +4.0 V) to increase pump displacement and decrease positive voltage (i.e. +3.5 V to +3.0 V) to decrease pump displacement. For reverse movement, the TCU will increase negative voltage (i.e. -3.5 V to -4.0 V) to increase pump displacement and decrease negative voltage (i.e. -3.5 V to -3.0 V) to decrease pump displacement. The TCU also applies voltage to the rear PCP in proportion to the front PCP for steering and counter-rotation commands. For more information on PCP operations, see Pump Pressure Control Pilot (PCP) Operation. (Group 9026-05.) If one of these component causes a DTC, either the forward or reverse functions will be disabled. Motor Speed Sensor (B3 and B7)—The motor speed sensors are feedback devices used by the TCU to determine actual track speed. The sensors enable the TCU to control tracking, thus allowing the machine to move in the desired motion. The TCU monitors track speeds and slows the faster track to match the slower track. Each sensor is supplied 5 volts and a ground reference from the TCU. The motor speed sensor right (B3) sends a pulsed signal to pin J2 of TCU connector X1. Motor speed sensor left (B7) sends a pulsed signal to pin H2 of TCU connector X1. If one of these sensors causes a DTC, the tracker function will be disabled and mistracking will occur. For motor speed sensor specifications, see Electrical Component Specifications. (Group 9015-20.) Motor Shift Solenoids (Y3 and Y4)—The TCU sends a signal from terminals D2 and F2 of TCU connector X2 to energize the shift solenoids. With the solenoids energized, the hydrostatic motors are at minimum displacement. As transmission speed increases from 2.1 to 2.2, the TCU will simultaneously energize the motor shift solenoids to bring the motors to minimum displacement and reduce voltage to the pump PCPs to reduce pump displacement. This provides smooth acceleration between motor speeds. If one of these components cause a DTC, the maximum machine speed will be limited to 5.23 km/h (3.25 mph). For more information on the motor shift solenoids and motor operation, see Hydrostatic Motor Operation. (Group 9026-05.) For solenoid specifications, see Electrical Component Specifications. (Group 9015-20.) Charge Pressure Sensor (B33 or B41) NOTE: The charge pressure sensor is B33 for (S.N. —173344) and B41 for (S.N. 173345— ). The charge pressure sensor provides the TCU with a variable resistance based on charge pressure. The charge pressure sensor receives 5-volt power from pin E1 of TCU connector X1 and a ground reference from pin E3 of TCU connector X1. The TCU measure sensor resistance at pin K2 of TCU connector X1. The TCU transmits this information across the CAN data line to the SDM. The charge pressure can be displayed as a live value on the SDM. See Standard Display Monitor (SDM) Menu Structure—Service Mode. (Group 9015-16.) If the charge pressure drops below 1310 kPa (13.1 bar) (190 psi) for more than 10 seconds while the engine is running, machine speed will ramp down and the machine will stop. Forward and reverse functions will be disabled, the engine speed will be limited to slow idle, and a diagnostic trouble code (DTC) will be generated. When the malfunction is fixed, the key switch must be cycled to clear the code. If the charge pressure exceeds 3447 kPa (34.5 bar) (500 psi) and the transmission oil temperature is above 32°C (90°F), or if the charge pressure exceeds 5170 kPa (51.7 bar) (750 psi) at any temperature, the TCU will transmit this information across the CAN data line to the ECU, which will then limit the engine speed to 1200 rpm. When the malfunction is fixed, the key switch must be cycled to clear the code. For charge pressure sensor specifications, see Electrical Component Specifications. (Group 9015-20.) Engine Speed Control (R10)—The engine speed control is a potentiometer which receives 5-volt power from pin G1 of TCU connector X1 and a ground reference from pin G3 of TCU connector X1. Turning the engine speed control sensor varies the amount of voltage sent to pin G2 of TCU connector X1. This signal represents desired engine speed, which the TCU compares with values recorded during TCU calibration, then transmits the engine speed command as a percentage across the CAN data line. The ECU detects this signal and responds by increasing or decreasing engine speed accordingly. The ECU detects the signal representing actual engine speed from crankshaft position sensor (B6). The ECU transmits the engine speed signal across the CAN data line. The TCU detects the actual engine speed signal and compares it to the desired engine speed command signal for antistall purposes. If the load on the engine causes the engine to pull down, the TCU will send the appropriate current to PCP solenoids (B8 and B9) to decrease pump displacement and prevent the engine from stalling. The TCU uses the engine speed to determine the pump speeds. For more information on the ECU, see Engine Control Unit (ECU) Circuit Theory of Operation. (Group 9015-15.) If machine is started and the TCU does not measure voltage at pin G2 that represents slow idle command, the engine speed control sensor must be rotated to slow idle position before the engine speed can be increased. If this sensor causes a DTC, engine speed will be limited to slow idle and machine speed will be limited to creep. If this sensor causes a calibration code, the TCU default values will be used for this sensor. Backup Alarm (H6)—When the key switch is ON and reverse travel is selected, the TCU will send current out pin F3 of TCU connector X2, to the backup alarm (H6), activating the alarm.

The IGC system is an electric-over-hydraulic, plug and play control system designed to be an integral part of a fully automatic system using global positioning system (GPS) and/or laser guidance equipment provided by a third party. The base system consists of the following components:

• IGC Load Center (A8) • Electrohydraulic Controller (EHC) (A11) • Blade Control Joystick (BCJ) (A9) • Electrohydraulic Actuators (Y30—Y32) IGC Load Center (A8)—The IGC load center provides power to electrohydraulic controller (EHC) (A11), the four-way axis module of blade control joystick (BCJ) (A9), and the grade control supplier's equipment [IGC interface connector (X96)]. Unswitched battery power is provided to the IGC load center from batteries (G1). Switched power is provided to the IGC load center through 5-amp fuse (F29). The IGC fuse and relay box consists of the following components:

• IGC Switched Power 15-Amp Fuse (F101) • BCJ Switched Power 5-Amp Fuse (F102) • EHC Switch Power 10-Amp Fuse (F103) • IGC Unswitched Power_1 10-Amp Fuse (F104) • IGC Unswitched Power_2 10-Amp Fuse (F105) • IGC Unswitched Power_3 10-Amp Fuse (F106) • IGC Switched Power Relay (K101) • BCJ and EHC Switched Power Relay (K102) Electrohydraulic Controller (EHC) (A11)—The EHC is the machine's control center for the IGC system. The EHC powers up when switched power from 10 amp fuse (F103) is supplied to the EHC at pins 1 and 18 of connector (X83). Ground is provided at pins 6 and 23 of EHC connector (X83). When powered up, the EHC provides 5 volts at pin 3 of EHC connector (X82). The 5 volts are sent to pin 1 of BCJ switch module connector (X97), pin 1 of auxiliary joystick connector (X85), and pin 2 of hydraulic enable switch (S30). The EHC provides a ground for the 5-volt circuit at pin 22 of EHC connector (X82). This ground is available at pin 6 of the BCJ switch module connector and pin 4 of the auxiliary joystick connector. Putting the hydraulic enable switch to the DISABLED position sends 5 volts to pin 17 of EHC connector (X82). When the EHC detects 5 volts at pin 17 and no voltage at pin 18, the EHC disables all outputs to the electrohydraulic actuators (Y30—Y32). During this time, the blade controls will not function in manual or auto modes. Putting the hydraulic enable switch to the ENABLED position, sends 5 volts to pin 18 of EHC connector (X82). When the EHC detects 5 volts at pin 18 and no voltage at pin 17, the EHC enables all outputs to the electrohydraulic actuators allowing the blade controls to operate when commanded. If the EHC detects voltage at pins 17 and 18 of EHC connector (X82) at the same time, or no voltage at either pin at the same time, the EHC will disable the outputs and generate a diagnostic trouble code (DTC). The DTC information is transmitted through the machine CAN data link to standard display unit (SDM) (H1) to alert the operator. See Electrohydraulic Controller (EHC) Diagnostic Trouble Codes. (Group 9001-40.) When in manual mode, or manual override when in auto mode, the EHC receives blade control commands from the blade control joystick, then sends corresponding signals to the appropriate electrohydraulic actuators to move the blade to the desired position. When in auto mode, the EHC receives blade control commands from the grade control supplier's equipment, then sends corresponding signals to the appropriate electrohydraulic actuators to move the blade to the desired position. The EHC communicates with the grade control supplier's equipment through the IGC CAN data link. The IGC CAN data link connects pins 10 and 11 of EHC connector (X82) to pins G (shield), H, and J of IGC interface connector (X96). The EHC communicates with blade control joystick (BCJ) (A9) and standard display monitor (SDM) H1 through the machine CAN data link. The machine CAN data link connects pins 7 and 8 of EHC connector (X82) to pins 3 and 4 of BCJ connector (X98) and pins C and K of SDM connector (X6). NOTE: For EHC diagnostics, see Integrated Grade Control (IGC) Checks—If Equipped. (Group 9015-20.) For EHC diagnostic trouble codes, see Electrohydraulic Controller (EHC) Diagnostic Trouble Codes. (Group 9001-40.) Blade Control Joystick (BCJ) (A9)—The BCJ consists of a four-way axis module and a switch module (located in the joystick handle).

• Four-Way Axis Module: The BCJ four-way axis module controls blade lift and tilt in correlation with joystick lever movement. Data representing position of the joystick lever is transmitted across the machine CAN data link to the EHC. The EHC converts the data representing joystick position to a corresponding analog signal, then sends this signal to the appropriate electrohydraulic actuator to move the blade to the desired position. The data representing joystick position is also sent to the SDM where it can be displayed on the SDM menu structure for diagnostic purposes.

NOTE: For information on accessing the SDM menu structure, see Standard Display Monitor (SDM) Menu Structure—Service Mode. (Group 9015-16.) For BCJ diagnostics, see Integrated Grade Control (IGC) Checks—If Equipped. (Group 9015-20.) For BCJ diagnostic trouble codes, see Blade Control Joystick (BCJ) Diagnostic Trouble Codes.

Sub-System Diagnostics

• Switch Module: The BCJ switch module contain switches that control auto/manual mode (IGC on/off), blade angle, blade height increment/decrement, and screen swap (not used). The information from the various switches is transmitted through separate wires to individual inputs on the EHC. The EHC transmits the BCJ switch information

through the machine CAN data link to the SDM where it can be displayed on the SDM menu structure for diagnostic purposes. - IGC On/Off Switch: Pushing the IGC on/off switch button sends a signal out pin 4 of the BCJ connector (X97) to pin 21 of EHC connector (X83). When the EHC receives a signal at this input, the EHC toggles the IGC system to either manual and auto mode, depending on which mode the system is presently in. Before the EHC does this, it must detect inputs from the grade control supplier's controller, the standard display monitor (SDM), the blade control joystick (BCJ), the transmission control unit (TCU) (park lock lever in DOWN position), and the hydraulic enable switch in the ENABLED position. - Screen Swap Switch (not used): Pushing the screen swap button sends a signal out pin 5 of the BCJ connector (X97) to pin 22 of EHC connector (X83). The screen swap switch has no function at this time so the EHC ignores this signal. - Blade Angle Switch: Pushing the upper button of the blade angle (rotate) switch sends approximately 3.00 volts out pin 2 of the BCJ connector (X97) to pin 20 of EHC connector (X82). This causes the EHC to send current out pin 12 of EHC connector (X83) to pin 1 of blade angle actuator (Y30) (blade rotates to right). Pushing the lower button of the blade angle (rotate) switch sends approximately 0.90 volts to pin 20 of EHC connector (X82). This causes the EHC to send current out pin 5 of EHC connector (X83) to pin 4 of blade angle actuator (Y30) (blade rotates to left). When the blade angle switch is in neutral position, the BCJ sends approximately 2.20 volts to pin 20 of EHC connector (X82), causing the EHC to prevent any current flow to either pin 1 or 4 of the blade angle actuator. Blade angle stays in neutral - Blade Height Incr/Decr Switch: Pushing the upper button of the blade incr/decr switch sends approximately 3.00 volts out pin 2 of the BCJ connector (X97) to pin 21 of EHC connector (X82). If the system is in auto mode, the EHC will send an appropriate signal out pin 24 of EHC connector (X83) to pin 1 of blade lift actuator (Y32) (blade rises slightly). Pushing the lower button of the blade incr/decr switch sends approximately 0.90 volts to pin 21 of EHC connector (X82). If the system is in auto mode, the EHC will send an appropriate signal out pin 24 of EHC connector (X83) to pin 1 of blade lift actuator (Y32) (blade lowers slightly). When the blade incr/decr switch is in neutral position, the BCJ sends approximately 2.20 volts to pin 21 of EHC connector (X82), causing the EHC to take no action in regard to the blade increment and decrement.

Electrohydraulic Actuators—The base IGC system uses three electrohydraulic actuators:

• Blade angle actuator (Y30) • Blade tilt actuator (Y31) • Blade lift actuator (Y32) An auxiliary actuator can be added using connector (X90) to accommodate optional equipment such as a ripper. Each electrohydraulic actuator uses two pairs of solenoid valves to control the position of the actuator spool. One pair of solenoid valves control oil pressure at one end of the actuator spool. The other pair controls oil pressure at the opposite end of the actuator spool. Each pair contains a normally closed solenoid valve that controls supply (pressure) oil and a normally open solenoid valve that controls venting to tank. When in the neutral state, no current flows to either pair of solenoids, causing oil at both ends of the spool to vent to tank. With no oil pressure at either end of the spool, the centering springs will hold the spool at center (neutral) position. For more information on hydraulic operation of the actuators, see Hydraulic Control Valve Operation—IGC. (Group 9025-05.) Blade Angle Actuator (Y30): The blade angle actuator uses on/off type solenoid valves. Pins 2 and 3 of the actuator are connected to IGC ground (W20). When the EHC sends current to pin 1 of the actuator connector, the corresponding pair of solenoids are energized, causing the actuator spool to move to maximum stroke. With the actuator spool shifted, the blade rotates to the right. When the EHC sends current to pin 4 of the actuator connector, the other pair of solenoids are energized, causing the actuator spool to move in the opposite direction to maximum stroke. With the actuator spool shifted in the opposite direction, the blade rotates to the left. Blade Tilt Actuator (Y31): The blade tilt actuator uses proportional type solenoid valves. The EHC provides power out pin 19 of EHC connector (X83) to pin 4 of the actuator. Pin 3 of the actuator is connected to IGC ground (W20). For blade tilt operation, the EHC sends an analog signal out pin 20 of EHC connector (X83) to pin 1 of the blade tilt actuator. Depending on the blade operation, the analog signal will be one of three different voltage levels as follows:

• Blade tilt left = 6 volts (approximate) • Neutral = 12 volts (approximate) • Blade tilt right = 18 volts (approximate) The actuator's on-board controller converts the analog signal to individual pulse width modulated (PWM) signals that control each of the four proportional solenoid valves, which in turn, controls the position of the actuator spool. The position of the spool is monitored by an integral feedback sensor, which measures spool position relative to the input signal. When the feedback sensor detects the spool has reached the intended position, the on-board controller will stop the modulated signals to the four solenoids. The actuator has a built-in status light. If the actuator is operating correctly, the status light on the actuator will be green. If the actuator spool goes farther that the intended position as commanded by the input signal, the status light on the actuator will turn to red and a signal will be sent out pin 2 of the actuator to pin 4 of EHC connector (X83). When the EHC receives this signal, the EHC generates a diagnostic trouble code (DTC) and transmits the DTC information through the machine CAN data link to the standard display monitor (SDM) to alert the operator. See Electrohydraulic Controller (EHC) Diagnostic Trouble Codes. (Group 9001-40.) Blade Lift Actuator (Y32): The blade lift actuator uses proportional type solenoid valves. The EHC provides power out pin 19 of EHC connector (X83) to pin 4 of the actuator. Pin 3 of the actuator is connected to IGC ground (W20). For blade lift operation, the EHC sends an analog signal out pin 24 of EHC connector (X83) to pin 1 of the blade lift actuator. Depending on the blade operation, the analog signal will be one of four different voltage levels as follows:

• Blade float = 6 volts (approximate) • Blade lower = 8 volts (approximate) • Neutral = 12 volts (approximate) • Blade raise = 18 volts (approximate) The actuator's on-board controller converts the analog signal to individual pulse width modulated (PWM) signals that control each of the four proportional solenoid valves, which in turn, controls the position of the actuator spool. The position of the spool is monitored by an integral feedback sensor, which measures spool position relative to the input signal. When the feedback sensor detects the spool has reached the intended position, the on-board controller will stop the modulated signals to the four solenoids. The actuator has a built-in status light. If the actuator is operating correctly, the status light on the actuator will be green. If the actuator spool goes farther that the intended position as commanded by the input signal, the status light on the actuator will turn to red and a signal will be sent out pin 2 of the actuator to pin 10 of EHC connector (X83). When the EHC receives this signal, the EHC generates a diagnostic trouble code (DTC) and transmits the DTC information through the machine CAN data link to the standard display monitor (SDM) to alert the operator.

Monitor Operation

Standard Display Monitor (SDM)—Setting Hour Meter This procedure is used to transfer current hour meter information to a new standard display monitor (SDM) when a new SDM is installed.

NOTE: The ones digit is set first, followed by tens, hundreds, thousands and ten thousands digits in that order. 8. Using the NEXT and BACK buttons, input the existing hour meter value to the nearest full hour (no tenths).

NOTE: The standard display monitor (SDM) only allows five SDM ON/OFF power cycles to input existing hour meter value. If the value is not entered during these five power cycles, the SDM hour meter value will reflect time accumulated since installation of new SDM.

a. Press and release the NEXT button to advance the number displayed in the active (flashing) field. The NEXT button increments the current digit and will “roll over” from 9 to 0. b. Press and release the BACK button to accept the number displayed (flashing) in the active field and shift the active field to the next digit to the left.

1. Record existing hour meter value before removing existing SDM.

c. If an incorrect value is entered and the active field advanced, continue to press and release the BACK button until the incorrect value is in the active field. Correct the value using the NEXT button.

2. Install new SDM. 3. Turn key switch to ON position. 4. Using Service ADVISOR™, download and install latest SDM software on new SDM as necessary. 5. Turn key switch OFF and then ON after software has been downloaded and installed. 6. SDM display shows SELECT SET HOURS, press the SELECT button.

9. Once the existing hour meter value has been entered, press the SELECT button to store these values. 10. SDM display shows VERIFY XXXXX (XXXXX is the newly-entered hour meter value). 11. If the displayed value is correct, press the SELECT button to permanently store the value.

7. SDM display shows SET HOURS 00000. Last digit will be flashing.

If the displayed value is not correct, press the BACK button to re-enter the existing hour meter value.

Transmission Control Unit (TCU) Calibration Whenever transmission components are adjusted or replaced, the transmission control unit (TCU) calibration procedure must be performed. The TCU calibration procedure must be performed on level ground with enough room to accelerate to full speed for approximately 46—61 m (150—200 ft) or with machine off ground supported by blocks. Before performing the TCU calibration, clear tracks of excessive mud and verify track tension is within specification. See check track sag. (Operator's Manual.)

3. Start engine and warm machine to normal operating temperature. See Transmission Oil Warmup Procedure. (Group 9026-25.) 4. Check charge pressure during machine warmup by observing charge pressure reading on standard display monitor (SDM). If charge pressure is low, see High/Low Charge Pressure Malfunctions. (Group 9026-15.) 5. Select CALIBRATE in the Service Mode menu of the SDM. See Standard Display Monitor (SDM) Menu Structure—Service Mode. (Group 9015-16.) 6. Choose one of the following calibration modes by pushing the UP or DOWN buttons on the SDM, then push the SELECT button.

IMPORTANT: If pump was repaired or replaced, perform the pump null adjustment before performing TCU calibration to prevent possible machine damage. See Pump Displacement Control Valve (PDCV) Neutral (NULL) Adjustment. (Group 9026-25.)

• 1 FULL CAL—Calibrates all TCU inputs and outputs.

1. Check for diagnostic trouble codes (DTC). If DTC 158.3, 158.4, 620.3, or 620.4 is displayed, DO NOT perform the calibration procedure. Repair problem causing the code(s) before continuing with calibration procedure. See Transmission Control Unit (TCU) Diagnostic Trouble Codes. (Group 9001-30.) 2. Make sure park lock lever is in the LOCK (up) position and TCL is in neutral.

Use after any major component is repaired or replaced. • 2 SECTIONAL CAL—Calibrates TCU input and outputs individually as chosen. - Sensor Cal - Pump/Motor Cal - Motor Cal

7. Follow the commands displayed on the SDM. If any problems occur during the calibration period and the calibration procedure ends prematurely, check for diagnostic trouble codes. See Standard Display Monitor (SDM) Menu Structure—Service Mode. (Group 9015-16.) MH66O88,00008E7 -19-08JAN08-1/1

Integrated Grade Control (IGC) Checks—If Equipped Most problems with the IGC electrical control system will cause a diagnostic trouble code (DTC) to appear on the SDM or grade control supplier's monitor. Fixing the problem causing the DTC will usually resolve the overall problem.

Use the following series of checks, in conjunction with the IGC observable symptom diagnostics, to help determine what part of the IGC system is responsible for the malfunction. For IGC observable symptoms diagnostics, see Integrated Grade Control (IGC) Diagnose Malfunctions—If Equipped. (Group 9015-20.) TW73308,0000125 -19-07JAN08-1/11

Group 05

Theory of Operation Hydraulic System Operation This machine has an open-center hydraulic system. Oil flows from the sealed hydraulic reservoir to the hydraulic external gear pump. The pump is bolted to, and driven through, the hydrostatic pump stack. Oil from the hydraulic pump flows to the inlet of the control valve. The control valve is an open-center, three-spool stack-type valve. Sections are connected in parallel, permitting multiple dozer functions to be used at the same time. The valve controls the blade lift, angle, and tilt functions. On these machines a fourth auxiliary section can be added for use with rear-mounted equipment. Each section contains a lift check poppet to prevent oil on the actuated side of a cylinder from flowing back through the valve section. The lift check poppets also prevent interaction between actuated sections.

The blade lift section contains a detent to hold the spool in the float position. The spool must be manually released from the float (detent) position. With no function actuated (neutral spools), all oil is directed to the outlet section outlet port by the valve spool. This oil flows through a hydraulic oil cooler or directly to the return oil filter and back to the hydraulic oil reservoir. When a function is activated, oil flow through the open-center passage is restricted or stopped. Oil flows through the valve section to work port and cylinder. Oil from the cylinder is forced back to the other work port, through the control valve return passage, out the outlet section return port through a hydraulic oil cooler or directly to the return oil filter and then back to the hydraulic oil reservoir.

The inlet section contains a system relief valve. This section also contains a hydraulic test port to check oil pressure. SW03989,00001DD -19-07DEC07-1/1

The hydraulic pump (10) is an external gear pump mounted to the rear end of the tandem hydrostatic pump assemblies. The tandem hydrostatic pump assemblies are mounted to the rear of the engine. Low pressure oil (15) is routed to the pump by a suction hose (8). Pressure oil (13) is routed by a pressure hose (9) to the inlet port of the hydraulic control valve (1). The control valve is located in a compartment on the right side of the operator cab in front of the hydraulic reservoir (5). A service door on the right side of the operator cab provides access to a number of hydraulic components. The control valve is an open-center design that continually directs return oil either through the hydraulic oil cooler (12) and then to, or directly to, the hydraulic oil filter (2). Later models route all cooler oil directly to the reservoir and is not filtered. In addition an orifice was added in cooler return line to cooler from the control valve. See Hydraulic Component Location, or see Hydraulic Component Location—IGC. (Group 9025-15.)

13— Pressure Oil 14— Return Oil 15— Low Pressure Oil

The hydraulic filter is a spin-on type, vertically mounted in the service compartment. Return oil then enters the hydraulic reservoir through the return oil tube (6) that is welded through the front panel of the reservoir and extends in and down, close to the bottom of the reservoir. The hydraulic reservoir is a welded assembly with a bolt-on cleanout access cover (3), which is sealed with a gasket. The cleanout access cover is located on the front panel of the reservoir with access through the service door. The reservoir oil fill cap (4) is located on the right side of the hydraulic reservoir. The oil level sight gauge is inside the service compartment, next to the hydraulic filter. A drain port (7) is also located at the bottom of the front panel of the reservoir. Access to the drain is made through the service door and an access panel on the bottom of the hydraulic service compartment. SW03989,00001DE -19-09MAR10-2/2

Filter restriction indicator switch (3) works on same principle as the filter bypass valve. High pressure oil is sensed through the high pressure passage (1). Restricted oil flow (8) caused by a clogged filter element (6) will create higher oil pressure on the inlet side. When this inlet pressure overcomes outlet pressure plus switch spring (4) force, the switch moves right (closes) providing

a ground for the filter restriction indicator. The switch causes an indicator light on the standard display monitor (SDM) to illuminate. The filter restriction indicator switch is set to close at 68 kPa (0.7 bar) (10 psi) before the bypass valve opens. This will allow the operator to perform maintenance of hydraulic system before unclean oil passes through hydraulic oil system.

The hydraulic control valve is designed to be used with the optional Integrated Grade Control (IGC). See Hydraulic System Schematic—IGC, see Hydraulic Component Location—IGC (Group 9025-15), and see Integrated Grade Control (IGC) Circuit Theory of Operation—If Equipped. (Group 9015-15). The control valve is a closed-center, load sensing (LS), proportional valve type, with unloading valve and electrical actuation. The control valve is sectionalized, and is composed of the inlet/outlet section (3), blade angle section (5), blade tilt section (7), blade lift section (10), and the outlet section (19). An optional auxiliary section (20) is also available. Supply oil from the fixed displacement pump enters the control valve port P. The internal passage P routes supply

oil to the unloading valve, the pressure reducing valve, each compensator valve, and each blade function spool. The pressure reducing valve regulates the pressure of the supply oil to the blade actuators. When a function is actuated, supply oil flows through the compensator valve and is routed through the function spool to the cylinders. At the same time, supply oil is also routed through the function spool to the spring chamber of the compensator valve, LS shuttle valve, and the LS signal circuit. Return oil from the cylinder is routed back through the function spool and out of the control valve port T, where it is routed through the hydraulic oil cooler, hydraulic oil filter and bypass and then the reservoir. All cooler oil is directly sent to reservoir and is not filtered.

Theory of Operation

When one or more of the spools are actuated, the highest load pressure is sensed through the LS signal circuit at the spring chamber of the unloading valve. This pressure completely or partially closes the unloading valve connection to tank. Pump pressure is applied to the opposite side of the unloading valve, thus regulating the pump pressure. The compensator valve maintains a constant pressure drop across the main spool when the load changes or when a section with a higher load pressure is actuated. This means that all work sections will continue to function regardless of differences in their load and regardless of the pump flow.

B, but are not used in this application. Therefore the limiting valves adjusting screws must be turned in completely to ensure maximum available pressure to the lift cylinders. The electrohydraulic blade function actuators are controlled by a signal from the electrohydraulic controller (EHC). See Integrated Grade Control (IGC) Circuit Theory of Operation—If Equipped. (Group 9015-15.) The actuators control the function spools by varying the flow of oil to and from the ends of the spool. In this way precise placement of the spool is accomplished.

The hydraulic cylinders are John Deere 120 Series design. The barrel (1) is welded to the head end and the rod (2) is welded to the rod eye. The piston (3) is retained on rod by a nut (4). The rod guide (5) is retained in the barrel by a snap ring and held against the snap ring by a spanner nut (6) or a snap ring (angle cylinder only). A cap seal (7) is used to seal the piston to the barrel (1).

The rod guide (5) uses a cup seal against the rod. A step seal (8) is used ahead of the cup seal. The step seal reduces the oil pressure to the cup seal resulting in a more durable rod guide seal. Dozer angle cylinders have short grooves in barrel head end to relieve pressure when cylinder is fully retracted. CED,TX03768,2299 -19-05MAR04-1/1

Oil Clean-up Procedure This procedure is to be used on machines that have had hydraulic system repair without a catastrophic component failure. Filter procedure must be done prior to starting machine after a component has been repaired or replaced. The use of attachments increase the need to monitor and filter oil to a safe contamination level. IMPORTANT: Oil types and filters should not be intermixed. Use filter element in same type oil to avoid intermixing of oils. Avoid operating filter caddy in dusty or wet conditions. Oil contamination could result. Filter caddy requires a 20 amp electric circuit. Use of electrical extension cord is not recommended.

T200210A —UN—21MAY04

NOTE: Instrument cleanliness and clean practices are critical when filtering oil or taking oil samples. Dust, wind, and moisture, as well as contaminated sample pumps, bottles and tubing can effect results. 1. Install proper particle filter cartridge and water filter for type of oil to be filtered. 2. With machine off, remove tank cap slowly to release pressure in hydraulic or hydrostatic oil tank. 29— Oil Filter Storage

20. Move caddy control switch to AUTO position. 21. Push start button. NOTE: Higher viscosity oil or filter elements that have reached a higher level of contamination, can cause the CHANGE FILTER indicator to come on. Flow rate can be reduced to allow continued use of filter. Filter element should be changed as filtering time increases because flow rate is reduced and possible filter element by-pass.

22. Rotate oil flow control knob to approximately full flow. Adjust flow to prevent caddy pump cavitation. Pump cavitation will aerate oil and cause ISO particle count to increase. Reduce flow rate to allow continued use of filter with higher levels of contamination. Filter element should be changed as filtering time increases. Filter elements should be changed to avoid system filter by-pass. Dispose of contaminated filters properly.

27. Red filter change indicator (11 and 12) will illuminate should filters become contaminated and restrict oil flow. Flow rate can be reduced to allow continued use of filter. Filter element should be changed as filtering time increases. Filter elements should be changed to avoid system filter by-pass. Dispose of contaminated filters properly.

23. Release air trapped in particle filter cartridge container again. Close when oil flow is steady.

28. When filter caddy is OFF remove filter caddy wands from tank. Wipe wands clean and place in caddy holder.

24. Check flow meter for oil flow rate.

29. Replace hydraulic oil tank cap.

25. Flush sidewalls and bottom of oil tank with discharge wand to loosen oil contaminants and mix with tank oil. Maintain oil suction wand positioned near bottom of tank. Oil discharge wand should be kept under the oil surface as much as possible to avoid aeration of oil. Air trapped in the oil will cause particle count to raise above actual contamination level. 26. Use CODE SCROLL button (18) on lower right corner on ISO Code monitor (4) to scroll and view ISO Codes at 4, 6, and 14-micron (c) sizes. ISO Code counts in each position should be within 3 of each other. Caddy will stop when particle count is approximately ISO Code 13 or lower at 14-micron (c) setting. SYSTEM

CAUTION: Avoid entanglement and possible electrocution from filter caddy power cord. Do not operate machine while filter caddy is connected to machine. IMPORTANT: Do not force the hydraulic system over system relief or over the return filter by-pass. 30. Perform start-up and bleed procedures for components to prevent component damage during startup. See technical manual for start-up and bleed procedures.

31. Keep hydraulic oil tank filled to specified operating level. See Check Hydraulic Oil Level. (Operator's Manual 3-4.) 32. Run machine at slow idle. Operate each circuit a minimum of two minutes in each direction to flush any remaining contaminants back through hydraulic oil machine filter. 33. Filter oil again. Repeat process until oil has been cycled through all functions 3—5 times and oil contaminant level is ISO Code 13 or lower at 14-micron (c) level. Use CODE SCROLL to check 4 and 6-micron (c) levels. ISO codes should be within 3 of each other.

38. Return machine to service. NOTE: Additional filtration equipment is recommended for machines in extreme environments. By-pass filtration systems are available. 39. Check and record oil particle counts. After a 100 hours of operation check oil particle count to confirm system is within ISO particle count specification. See Follow-Up Oil Cleanup Procedure. (CTM310.) Some hydraulic systems may not be able to maintain ISO Code 19/16/13 without additional filtration equipment. Auxiliary hydraulic attachments or components can be a point of entry for contamination. Frequent component changes also increase the chances for contaminants to enter the hydraulic system. Use care when connecting and removing components to not introduce contamination. Quick couplers should not be connected until they have been cleaned and capped when not in use. Fluid sampling and filter changes should increase if the application requires frequent component changes.

34. When machine reaches acceptable level of cleanliness, install new machine hydraulic oil return filter. 35. Fill tank to proper operating level. NOTE: Instrument cleanliness and clean practices are critical when filtering oil or taking oil samples. Dust, wind, and moisture, as well as contaminated sample pumps, bottles and tubing can effect results. 36. Obtain oil sample for fluid analysis. Oil sample should be taken just before the return filter when oil is warm.

40. Every Six Months for validation purposes use sample valve on Super Caddy to check for correct instrument readings. Results from lab cannot be identical to Super Caddy particle counter readings, but a correlation should exist. If validation testing shows a discrepancy of more than one code per particle size, sample oil again. If discrepancy in instrument readings persist, the particle counter must be checked by PALL Corporation.

Group 05

Theory of Operation Hydrostatic System The dual path hydrostatic drive system consists of axial piston pumps and 2-position axial piston motors. The transmission control is governed by an electronic controller. The pumps are mounted directly to the engine in a tandem configuration and are designed for through torque capability. This means the main hydraulic pump and the winch can be driven from the back of the tandem pump. High pressure hoses transmit pump flow to the motors. The variable displacement 2-position motors are mounted directly to the final drive. The transmission control can be divided into three groups: inputs, outputs and feedbacks. The operator sends inputs into the transmission controller from steering sensors, decelerator sensor, FNR sensor, transmission speed control sensor and engine speed control sensor.

The transmission controller sends a current signal to the Pressure Control Pilot (PCP) on each pump. The PCP is a servo valve which produces a hydraulic pressure differential relative to amount of current. The pressure differential is sent to the Pump Displacement Control Valve (PDCV) on the pump. The transmission controller also sends a current signal to energize the solenoid valve on the motor. The motor is normally held at its maximum displacement (lower speed, up to 3.25 mph). Energizing the solenoid will cause the motor to go to its minimum displacement (higher speed, above 3.25 mph). The left and right track motor speed sensors provide the feedback to the transmission controller for tracking. Rpm feedback for anti-stall is read from engine controller. The transmission controller compares the operator input command and the feedback from the sensors and regulates the output accordingly. CED,TX03543,2286 -19-16MAY03-1/1

The charge pump is an integral part of each hydrostatic pump. The charge pump is a gerotor type pump and is driven directly at engine speed. Each pump has a separate suction line from the reservoir (2). Charge pressure oil from each pump is then combined and sent to a single

filter (1). Passing through the filter, the charge oil is routed to the control circuit for each hydrostatic pump and to the park brake valve. A neutral charge relief valve located on the front pump return line from the hydrostatic filter regulates charge pressure and protects the charge pumps. CED,TX03543,2288 -19-07OCT98-1/1

5— Bypass Valve 6— Filter Element 7— Inlet 8— Outlet

The hydrostatic filter removes contaminants from the hydrostatic oil system. The filter head (9) contains a bypass valve (5) and a filter restriction indicator switch (3). Under normal operation, charge pressure oil (9) enters the inlet (7), flows through the filter element (6), up through the filter canister, and out the outlet (8) to the neutral charge relief, park brake valve, pump pressure control pilot valve (PCP), and pump displacement control valve (PDCV) control circuit for each hydrostatic pump. If the pressure differential between the inlet and outlet increases past a set level due to cold oil or partially restricted filter element, inlet pressure in the housing increases, moving the filter relief valve against spring force and outlet pressure. Inlet pressure also moves the switch piston causing the filter restriction indicator light to glow.

As the filter element becomes plugged, the pressure differential between the inlet and outlet increases. Inlet pressure is sensed on one side of the valve which opens against spring force and outlet pressure. The oil then bypasses the filter while the restriction indicator light glows. It is normal for the restriction indicator light to glow when operating the machine with cold oil. If the restriction indicator light continues to glow after the oil reaches operating temperature, the filter is being bypassed and the filter element should be replaced. Extended operation in the bypass mode could cause damage to the hydrostatic system.

Filter Operation—Restricted: Filter restriction indicator switch (3) works on same principle as the filter bypass valve (5). High pressure oil is sensed through the high pressure passage (1). When charge pressure oil (611) flow is restricted due to a clogged filter element (6) it creates higher oil pressure on the inlet (7) side. As the filter element becomes plugged, the pressure differential between the inlet and outlet increases. Inlet pressure is sensed on one side of the valve which opens

against spring force and outlet pressure. The oil then bypasses the filter while the restriction indicator light glows. It is normal for the restriction indicator light to glow when operating the machine with cold oil. If the restriction indicator light continues to glow after the oil reaches operating temperature, the filter is being bypassed and the filter element should be replaced. Extended operation in the bypass mode could cause damage to the hydrostatic system. JW40272,0000014 -19-04FEB10-3/3

Theory of Operation

When the park brake is applied or the machine is shut off, the park brake solenoid is de-energized. The solenoid valve blocks oil from the charge pump and opens the piston cavity to return. The springs force the piston towards the final drive compressing the pressure plates

against the friction disks. This locks the final drive gear to the brake housing to apply the brake. To manually release the park brake See Releasing Park Brake to Tow the Machine. (Group 9026-25.) TE14778,000001E -19-13JAN04-3/3

The multi-function valves are located in the pump end cap. There are two multi-function valves for each pump. The valves are in the closed-loop circuit. They sense closed-loop pressure. Two functions performed by each valve include closed-loop charge and high pressure relief. Closed-Loop Charge As soon as there is charge pressure, it is sensed at the check valve poppet (2). The

check valve also senses closed-loop pressure. Any time the closed-loop pressure is less than charge pressure the check valve moves the high pressure relief valve poppet (1) off its seat and there is charge flow into the closed loop. This keeps the closed loop filled with charge oil under all normal operating conditions. This function is similar to that of an anticavitation valve in a hydraulic system.

High Pressure Relief During normal operation of the machine, the pressure limiter poppet (3) senses closed-loop pressure and is held against its seat by spring force through the spring seat (4). Relief operation occurs when the closed-loop pressure on the limiter poppet overcomes the spring force on it causing it to move off its seat. In this condition there is oil

The oil flow through the orifice causes a pressure drop across the high pressure relief moving it off the valve seat. This allows closed-loop high pressure oil to flow past the poppet and into the charge circuit. CED,TX03543,2292 -19-03JAN06-2/2

The oil cooler bypass valve provides a means of quickly warming up the transmission oil after machine start up. The bypass valve prevents transmission cold oil from entering the cooler. The bypass also relieves cooling flow from the hydrostatic pump and motor cases directly to the reservoir in case the oil cooler becomes plugged. The operation of the oil cooler bypass valve is similar to that of a water thermostat in an engine. When oil temperature reaches approximately 140°, the thermostat begins to open. As oil temperature increases, the valve opens further until it reaches the full open position at approximately 165°.

5— To Reservoir 6— From Oil Cooler 7— Return Oil

This allows full case cooling oil to flow around the valve and out to the oil cooler. Return flow from the cooler goes around the land of the valve and returns to the reservoir. If the oil cooler becomes plugged, the pressure overcomes the relief spring and closes the valve. With the valve closed, case flow returns directly to the reservoir protecting the case seals and oil cooler from excessive pressure buildup. There is an indicator on the monitor that reads transmission oil temperature. The sending unit for the indicator is located in the case oil inlet to the bypass valve.

4— Nozzle 5— Flapper Valve 6— Charge Pressure Oil

There are two identical pressure control pilots (PCP's), one for each pump. The basic function of each PCP is to take a current signal from the transmission controller and convert it to a differential control pressure which is sent to each pump displacement control valve to regulate swash angles. The major components of the PCP are the torque motor and the flapper valve. The coil establishes a magnetic force to position the flapper valve. One coil is used for forward and reverse. The flapper is centered between two nozzles. Centering springs help keep the flapper at null. Upstream from each nozzle is an orifice which provides a nominal pressure drop when the system is at null. With the flapper at null there is equal charge oil flow and both output pressures are equal. When the machine is in neutral, no current signal is sent to the torque motor. The centering springs hold the flapper in a null (centered) position. Charge oil is equal through both upstream orifices and through each nozzle. With equal flow and pressure drop the two output pressures are exactly the same and the pressure differential is zero. In this condition the pump swash angle will be zero and the motor will be at maximum swash angle.

7— Low Pressure Control Oil 8— Return Oil

When the machine is in forward, the transmission controller will send a positive current signal to the coil in the pump PCP's. The coil produces a magnetic field in a given direction which in turn causes the flapper to move accordingly. The flapper restricts oil flow through one nozzle and opens the other. This produces a higher pressure at the restricted nozzle and a lower pressure at the unrestricted nozzle. Thus an output pressure differential is produced. This in turn will cause the pump displacement control valve to increase the pump swash angle and increase machine speed. For reverse operation, the transmission controller sends a negative current signal in the opposite direction compared to forward. Thus the magnetic field in the pump PCP is in the opposite direction which cause the flapper to move toward the opposite nozzle orifice. There is a manual mode which is controlled by a small external lever on the PCP. The lever is connected to the flapper valve. The lever can be moved in both directions which causes the flapper valve to move the same as with a current signal. This will manually override the transmission controller current signal.

The major components in the pump displacement control valve are the valve spool with centering spring, feedback linkage to the pump swash plate, and a null adjusting screw. The PDCV is supplied with charge pressure and a differential control pressure from the Pressure Control Pilot (PCP). It produces a servo pressure at two output ports which directs the pump servo piston. In a neutral condition with zero differential control pressure, the valve spool is centered by the feedback linkage and the centering spring. Charge pressure is blocked at the spool center and both output ports are connected to case. In forward, a given differential control pressure will shift the spool against the centering spring. Charge oil is now directed to the servo piston that swashes the pump in forward. As the swash plate moves, the feedback linkage

7— To Pump Servo 8— To Pump Servo 9— Charge Pressure Oil 10— Low Pressure Control Oil

causes a movement on the centering spring opposite to that of the differential control pressure. The spool moves back toward neutral to a point where a given servo pressure is maintained to the servo piston. This provides control of the pump swash plate relative to differential control pressure. In reverse the PCP produces a differential control pressure of the opposite polarity, the spool is moved in the opposite direction and charge oil is directed to the opposite servo piston. Thus the pump is swashed for reverse operation. The null adjust screw through the feedback linkage adjusts the centering position of the spool. The adjustment is made so that with no current signal to the PCP the valve spool is exactly centered. Charge pressure is blocked and both output ports are connected to case.

Two pumps are mounted directly to the engine in a tandem configuration and are designed for through torque capability. This means the main hydraulic pump and the winch can be driven from the back of the tandem pump. Each pump consists of a nine piston rotating group of the parallel axial piston/slipper design, a tiltable cradle swash plate that controls pump flow and direction and a integral geroter type charge pump mounted on the pump drive shaft. A hydraulic displacement control valve directs swash plate angle through a double servo piston assembly and a pressure control pilot (PCP) which controls the hydraulic displacement control valve. The output of the PCP is controlled by a milliamp current signal from the transmission controller. In addition each pump has two multi-function valves in the end cap. The front pump is connected to the right motor by pressure hoses. In the same manner the rear pump is connected to the left motor.

movement of the pistons and no pump flow. In forward the transmission controller sends an current signal to the pressure control pilot (PCP) which sends a differential control pressure to the pump displacement control valve (PDCV). The PDCV sends a controlled charge pressure to one of the servo pistons. As the piston is moved the swash plate which is connected to it also moves. Now with a given amount of swash plate angle, there will be a given amount of axial movement of pistons and a given amount of pump flow. In reverse the transmission controller sends a current signal of opposite polarity to the PCP. In turn then all the control signals and movements are reversed. With the swash plate movement reversed the pump output will be switched from one side of the closed loop to the other side. The pump is protected from high pressure by two multi-function valves, one for each direction.

Both pump rotating groups turn at engine speed. In neutral the swash plate is at zero and there is no axial CED,TX03543,2296 -19-16MAY03-1/1

The flushing valve and the operating charge relief valve are a part of the closed loop and are used to cool both the oil and the hydraulic components of the closed loop circuit.

operating charge relief valve. Its setting is approximately 30 psi below that of the neutral charge pressure relief valve. With this pressure difference relationship and with pressure oil taking the path of least resistance, there will be oil flow through the operating charge pressure relief valve. In this condition, oil on the low pressure side of the closed loop will be lost through the flushing and operating charge pressure relief valves. To make up for this loss, cool filtered oil from the charge circuit will enter the low side of the closed loop through the multi-function valve. Thus there is constant flow of clean cool oil into the closed loop when in forward.

The flushing valve (shuttle valve) is a spring balanced spool that senses pressure on both sides of the closed loop. The operating charge pressure relief valve is of the direct acting, orificed, poppet type design. In neutral with equal pressure on both sides of the closed loop, the springs center the flushing valve spool. In the centered position operating charge pressure relief valve is not connected to the closed loop. The closed loop pressure is controlled by the neutral charge pressure relief valve. In forward, one side of the closed loop will be at a higher pressure than the other. The flushing valve senses this and shifts away from the high pressure. In this position the lower pressure side of the closed loop is connected to the

In reverse, the closed loop pressures switch from one side to the other, the flushing valve shifts to the opposite side and the low side pressure is again connected to the operating charge pressure relief valve. As in forward the hot oil in the closed loop is routed out and clean oil is directed in. CED,TX03543,2297 -19-07OCT98-1/1

Two hydrostatic motors are mounted to the rear of the machine frame. The motors are two position, variable displacement. An internal shaft connects each motor to the final drive. The control utilizes an electric three way, two position, solenoid operated, hydraulic valve to port system pressure to the servo piston. The motor is normally held at its maximum displacement. Energizing the solenoid will shift the motor swash to minimum displacement.

pressure to the Pump Displacement Control Valve (PDCV). The PDCV will send differential control pressure to swash the pump from 0––16.5°. Until the pump swash reaches 16.5°, there will be zero voltage to the motor shift solenoid and the machine will remain at slow speed, maximum torque.

Neutral Operation

As the TCU receives input commands for increased speed, the current to the pump PCP increases. When the pump reaches its maximum swash (16.5°), the TCU also applies voltage to the motor shift solenoid, energizing the solenoid, sending closed loop pressure to the fast speed and slow speed ends of the servo piston. Since the differential area is greater on the fast speed end of the piston, it shifts, moving the motor swash from 23° to 19.5° degrees (fast speed, minimum torque). At the same time, the TCU applies a lower current to the pump PCP which in turn moves the pump swash angle from 16.5° to 13° degrees. As the command for speed increases the pump swash will continue until it again reaches 16.5° or maximum speed.

With the Transmission Control Lever (TCL) in neutral the Transmission Control Unit (TCU) applies zero voltage to the motor shift solenoid. Closed loop pressure, charge pressure when in neutral, is sent to the solenoid. With zero voltage at the solenoid, control pressure is routed to the slow speed end of the servo piston. Since the opposite end of the piston is connected to return, the piston shifts, moving the motor swash angle to the slow speed, maximum angle position. Therefore, when the TCL is moved out of neutral, the motor always starts turning at slow speed, maximum torque.

b. Pull park lock lever to up position.

D01182AA 20-Ton Floor Stands

The hydraulic and hydrostatic circuits have separate oil reservoirs. Use this procedure to stabilize and circulate warm oil to travel motors to meet hydrostatic (HST) test temperature specifications. The SDM monitor must be used to select Brake Test Mode which will keep the park brake applied for this procedure. CAUTION: Prevent possible injury from unexpected track movement. Raise the machine off the ground and support with appropriate stands. Tracks must be free to rotate in either direction, check for objects on tracks before rotating tracks. 1. Raise machine off the ground and support with D01182AA Floor Stands. Lower blade to the ground. Tracks must be free to rotate in either direction.

c. Push transmission control lever (TCL) to forward detent. IMPORTANT: To prevent damage to multi-function valves, the test software limits the test function to 20 seconds before returning TCU to neutral. The tracks must be operated between test function to prevent localized overheating of multi-function valves. Rotating the tracks will circulate hot oil out of closed loop circuit through the case drain filter, hydrostatic oil cooler, and to reservoir for cooling. d. Slowly release decelerator pedal and run until TCU returns to neutral, approximately 20 seconds. e. Go to next step and circulate oil. 7. Oil Circulate Cycle:

2. Start engine.

Test

IMPORTANT: To prevent damage to multi-function valves, the test software limits the test function to 20 seconds before returning transmission to neutral. The tracks must be operated between test functions to prevent localized overheating of multi-function valves. Rotating the tracks will circulate some hot oil out of closed-loop circuit to the hydrostatic oil reservoir for cooling. NOTE: Brake test mode allows the machine to be out of neutral for 20 seconds, after which the transmission control unit (TCU) returns the machine to neutral. Return transmission control lever (TCL) to neutral for at least 20 seconds before moving TCL to forward or reverse to start cycle again. 8. Check multi-function valve relief pressure: a. Depress decelerator/brake pedal to lower stop and hold in that position. b. Place transmission control lever (TCL) in appropriate detent corresponding with test being performed. Hold TCL to stop track on opposite side. (Test multi-function valve relief pressure one side at a time to obtain accurate results.) NOTE: In order to obtain an accurate gauge reading it is important not to flood the relief valve with excessive oil flow. Do not continue increasing engine speed after pressure levels out.

NOTE: Pressure should rise as the engine speed is slowly increased and then levels out. The point at which the pressure levels out is the relief valve setting. d. If high-pressure reading is erratic (very unstable), rotate tracks slightly to reposition motor speed ring and sensor. Repeat test. If pressures remain erratic, turn TRACKER CONTROL off in SDM and perform test. e. Compare reading to specification. If the relief setting cannot be reached at fast idle, then slowly increase transmission speed until pressure levels out.

The purpose of this test is to determine the amount of transmission internal leakage in the closed-loop components.

4. Install test fittings, lines, and gauge in motor test ports.

This is accomplished by determining the amount of oil the transmission pump must deliver to maintain a specified system pressure in the closed loop. This pressure is below the multi-function valve setting. Therefore, the amount of pump flow indicates the amount of internal leakage in the closed loop. The transmission controller sends a current signal to the Pressure Control Pilot (PCP) on each pump. The PCP produces a hydraulic pressure differential to the servo piston relative to the amount of current. By monitoring the current signal being sent to the PCP, the amount of leakage in the closed loop can be determined.

Each test port senses closed-loop pressure. • Use test ports (1 and 2) to check left motor (rear pump) relief setting. • Use test ports (3 and 4) to check right motor (front pump) relief setting. 5.

The compressor is belt driven and engaged by an electromagnetic clutch. The air conditioning circuit automatically controls compressor engagement or disengagement when system is in operation. See System Functional Schematic and Section Legend. (Group 9015-10.) Compressor draws low pressure gas from evaporator and compresses it into high pressure gas. This causes temperature of refrigerant to rise higher than that of outside air. High pressure gas leaves compressor and flows through condenser where heat is removed and transferred to outside air being drawn through condenser core by fan. Cooling refrigerant causes it to condense and refrigerant leaves condenser as high pressure liquid. High pressure liquid flows into receiver-dryer where moisture and contaminants (acid, solids, etc.) are

removed. Receiver-dryer may contain a color moisture indicator. (Blue) indicates no moisture is present. (Pink) indicates moisture is present. Should moisture be combined with refrigerant, hydrofluoric and hydrochloric acids are formed. These acids are very corrosive to metal surfaces and leakage will eventually develop. Receiver-dryer also stores refrigerant allowing a longer period of time before additional refrigerant is needed. Refrigerant hoses allow a small amount of refrigerant to migrate through their walls. Refrigerant flows from receiver-dryer through expansion valve to evaporator. Expansion valve senses refrigerant temperature and pressure to modulate refrigerant flow. Expansion valve changes refrigerant to low pressure liquid entering evaporator. Actual cooling and drying of cab air takes place at evaporator. Heat absorbed by evaporator and transferred to refrigerant causes refrigerant to vaporize into low pressure gas. Low pressure gas is drawn from evaporator by compressor and cycle is repeated.

Theory of Operation

A freeze control switch senses temperature of evaporator coil through a capillary tube. This prevents the evaporator from becoming cold enough to freeze moisture that condenses on evaporator coil. Condensed moisture is drained away through drain tubes connected to drain pan under evaporator. System pressure is monitored by high and low pressure switch, located on high pressure side of expansion valve. If pressure becomes too high or too low the switch opens and stops compressor, interrupting the cycle.

Accumulator is located between evaporator and compressor in low pressure gas hose to retain a quantity of oil to protect compressor from a dry start after long periods of not being used. See A/C Harness (W8) Component Location (Group 9015-10) for location of machine heater and A/C components.

Test Proper Refrigerant Handling The U.S. Environmental Protection Agency prohibits discharge of any refrigerant into the atmosphere, and requires that refrigerant be recovered using the approved recovery equipment. IMPORTANT: Use correct refrigerant recovery, recycling and charging stations. Do not use refrigerant, hoses, fittings, components

or refrigerant oils intended for use with R12 refrigerant. Recovery, recycling and charging stations for R12 and R134a refrigerants must not be interchanged. Systems containing R12 refrigerant use a different oil than systems using R134a. Certain seals are not compatible with both types of refrigerants. MODTX9031QQ2009 -19-06MAY04-1/1

R134a Refrigerant Cautions SPECIFICATIONS Maximum Amount To Heat Refrigerant In Closed Container Temperature

Do not heat refrigerant over 52°C (125°F) in a closed container. Heated refrigerant will develop high pressure which can burst the container.

52°C 125°F

CAUTION: Do not allow liquid refrigerant to contact eyes or skin. Liquid refrigerant will freeze eyes or skin on contact. Wear goggles, gloves and protective clothing.

Specification Maximum Amount To Heat Refrigerant In Closed Container—Temperature............................................................................................ 52°C 125°F

If liquid refrigerant contacts eyes or skin, do not rub the area. Splash large amounts of cool water on affected area. Go to a physician or hospital immediately for treatment.

Keep refrigerant containers away from heat sources. Store refrigerant in a cool place.

Do not allow refrigerant to contact open flames or very hot surfaces such as electric welding arc, electric heating element, and lighted smoking materials.

Do not handle damp refrigerant container with your bare hands. Skin may freeze to container. Wear gloves. If skin freezes to container, pour cool water over container to free the skin. Go to a physician or hospital immediately for treatment. TX,9031,JC1705 -19-01AUG12-1/1

Refrigerant Hoses And Tubing Inspection When a component is disconnected from the system, special care should be given to inspecting hoses and tubing for moisture, grease, dirt, rust, or other foreign material. If such contamination is present in hoses, tubing, or fittings and cannot be removed by cleaning, then replace parts.

tube connections. Dip O-rings in correct viscosity oil before assembling. IMPORTANT: Hose used for air conditioning systems contains special barriers in its walls to prevent migration of refrigerant gas.

Fittings that have grease or dirt on them should be wiped clean with a cloth dampened with alcohol. Chlorinated solvents (such as trichloroethylene) are contaminants, and must not be used for cleaning.

Do not use hydraulic hoses as replacement hoses in the air conditioning system. Use only certified hose meeting SAE J51B requirements.

To assist in making leak proof joints, use a small amount of clean correct viscosity refrigerant oil on all hose and MODTX9031QQ1882 -19-06MAY04-1/1
