PREPARATION

1. Before beginning the installation, thoroughly clean the vehicle to remove dirt and contaminants that might get into the hydraulic circuit.

2. Park the vehicle on a clean, level oor with adequate clearance to work around.

3. Do not attempt to loosen any hydraulic ttings while the engine is running.

4. Allow the motor and the hydraulics to cool until it is no more than warm to the touch before proceeding.

5. Prior to loosening any hydraulic ttings, be sure to have the appropriate plugs and caps available in order to limit loss of hydraulic uid from the open ttings.

PREVENT HYDRAULIC SYSTEM CONTAMINATION. It is essential to thoroughly clean hydraulic system ttings and hose connections prior to disconnecting or removing them. Use a spray

cleaner such as “Brake Clean” to prevent hydraulic system contamination. Note that o-rings used on ORB and ORFF type ttings may be damaged by solvent cleaners such as “Brake Clean”. If a tting is to be cleaned internally, the o-ring should rst be removed and cleaned with a berless cloth.

TO AVOID EXCESS LEAKAGE, DO NOT TURN THE STEERING WHEEL WHILE THE FITTINGS ON THE MANUAL STEERING VALVE ARE DISCONNECTED.

WARNING: HOT, HIGH PRESSURE FLUID HAZARD. Hydraulic oil may be hot and under

extreme pressure. To prevent serious injury or death, relieve system pressure and allow the

system to cool before repairing or disconnecting. Wear proper hand and eye protection when searching for leaks, using wood or cardboard instead of hands. Keep all hydraulic components in good repair.

WARNING: PINCH POINT HAZARD! To prevent serious injury or death, avoid unsafe practice

while manually operating hydraulic steering circuits. Keep others away and stay clear of

mechanical steering linkages.

INSTALLATION

If there are questions concerning the installation of the FieldPilot system on this vehicle, or due to

the changes in component specications the parts supplied in the kit are not exactly as presented

in this document, please contact your dealer or TeeJet Customer service representative for clarication before installation. TeeJet Technologies is not responsible for misuse or incorrect installation of the system.

NOTE: BE VERY CAREFUL TO ABSOLUTELY SECURE ALL CABLES AND HOSES SO THAT THEY

DON’T INTERFERE WITH THE MANY MOVING PARTS OF THE MACHINE!

1. PrePare the FieldPilot ValVe

Make sure the FieldPilot valve (C) is clean and free of dust. Work on a clean bench. Remove the plastic plugs and install the elbow adapters (U) in the P, T, and A ports. Install the straight adapters (T) in the LS and B ports.

Figure 1-2: Preparing FieldPilot Valve

2. INSTALL MOUNTING BRACKET

Locate the bolt as illustrated in Figure 1-3 and mount the bracket. The bolt is located under the machine to the left side next to where cables and hoses are run. A washer may be needed.

Figure 1-3: Mount the FieldPilot Valve Bracket

3. install FieldPilot ValVe

Using the hardware provided (B, F, G) attach the prepared FieldPilot valve to the mounting bracket (H) in the orientation shown.

4. install Pressure and tank hoses

The Pressure and Tank hoses will run from the FieldPilot valve to the boost valve block on the machine. Disconnect the Pressure and Tank lines from the Boost Valve block and install the run tees (S). Reconnect the lines to the run of the tees.

Install hose (L) from the P port on the FieldPilot valve to the branch of the run tee as illustrated. Install hose

(K) from the T port on the FieldPilot valve to the branch of the run tee as illustrated.

Figure 1-5: Install Pressure and Tank Hoses

5. INSTALL LEFT AND RIGHT STEERING HOSES

The steering hoses will run from the FieldPilot valve to the cylinder on each wheel. Disconnect the line from the left and right wheel cylinders and install run tees (P) as illustrated. Install hose (I) from the A port on the FieldPilot valve to the branch of the run tee on the cylinder of the left wheel. Install hose (J) from the B port on the FieldPilot valve to the branch of the run tee on the cylinder of the right wheel.

6. PrePare the shuttle tee

Install adapters (Q) in the two side ports of the shuttle tee (O). Install adapter (R) in the top port of the shuttle tee. Once the hoses are attached and tightened to the shuttle tee, it will be tied down with the tie straps (provided).

7. INSTALL LOAD SENSE HOSES

John Deere 4710

Locate the priority valve on the left side of the machine. Follow the hose indicated in the photograph and disconnect it from the load sense jam valve and shuttle. Connect this hose to one side of the shuttle tee. Connect hose (N) to the 90° adapter on the top of the shuttle and route it to the open port on the load sense jam valve and shuttle. Connect hose (M) to the other side of the shuttle and route it to the LS port on the FieldPilot valve.

Locate the priority valve on the left side of the machine. Follow the hose indicated in the photograph and disconnect it from the valve block located in the middle underneath the machine. Connect this hose to one side of the shuttle tee. Connect hose (N) to the 90° adapter on the top of the shuttle and route it to the open port on the load sense jam valve and shuttle. Connect hose (M) to the other side of the shuttle and route it to the LS port on the FieldPilot valve.

8. install the ValVe control cable

Connect the FieldPilot valve control cable (E) to the coils on the FieldPilot valve and route the cable into the cab. Connect it to the SCM harness. Do not be concerned at this time about which connector is connected to which solenoid coil.

Figure 1-10: Install Valve Control Cable

9. install steering disengage sensor

Remove the shields around the steering column in the cab. Mount the bracket from kit (W) as shown. Glue magnets to the steering shaft (the magnets will need to be cut in half because the shaft is small). Install the sensor in the bracket. Set the clearance between the magnet and the sensor as close to 1/8” as possible.

10. installation oF engage/disengage switch

Connect item (A) to the connector on the SCM harness labeled Remote Engage/Disengage. Install the push button in a location that is easily accessible during operation of the machine. This switch (A) is not required if the optional foot switch 32-04020 is used.

11. recommended electronics installation

The Steering Control Module (SCM) should be securely mounted as level as possible to the oor. It must be mounted with the arrows pointing toward the direction of travel. The control console can be mounted to the preference of the operator. The GPS antenna should be mounted as far forward as possible on the cab on a metal surface of at least 4” square.

12. VeriFY oPeration oF hYdraulics and set the steering control rate

Clean and pick up the area around the vehicle and make certain that it is safe to operate. Start the engine and check hydraulic connections for leaks. Rotate the steering wheel from one extreme to the other and back to center, check for leaks. While steering through the extremes of movement, check the cables and hoses for wear points and strain, adjust as necessary.

If using a Matrix series console and PWM control, then the oil ow rate adjustment is accomplished through the console. The target lock to lock time is 6 seconds and the Valve Frequency is 110. Refer to the Matrix manual for further instructions.

If using a CL220 or CL230 console then refer to the following instructions for adjusting the oil ow rate.

Adjust the hydraulic oil ow control knob on the FieldPilot valve to a starting posi¬tion of 3 1/2 turns from completely closed. Adjust the oil ow by turning the knob

clockwise to reduce ow (increase seconds) and counter-clockwise to increase ow (decrease seconds).

Use the electronic steering control console to perform the left to right steering test, counting the seconds to move the wheels from full left to full right and also in the opposite direction. It is a good idea to have the vehicle moving forward very slowly during these tests so there is not excessive side pressure on the tires. If you nd that the machine steers in the opposite direction from that being commanded in this steering test sequence, switch the valve connectors at the FieldPilot valve coils.

Do this a number of times, adjusting the oil ow between tests, until a lock to lock steering response of ap¬proximately 18 seconds is observed using a CenterLine® 220. Adjust to 14 seconds when using a CenterLine® 230BP. Use the locking nut to secure this ow setting. The coils on the FieldPilot valve also have manual push button overrides.

NOTE: To activate the manual overrides, a tool such as a small screwdriver or allen wrench must be inserted

into the end of the coil to depress the override button.

WARNING: PINCH POINT HAZARD! To prevent serious injury or death, avoid unsafe practice while manually operating hydraulic steering circuits. Keep others away and stay clear of mechanical steering linkages.
