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.
6. Remove the hood and side panels around the engine compartment to allow access to the hydraulic
system
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 specications the parts supplied in the kit are not exactly as presented
in this document, please contact your dealer or TeeJet Customer service representative for
clarication 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!
The Ford NH 8770 has a closed center steering with steel lines coming to and from the Orbital Valve. The
Pressure and Tank lines from the FieldPilot Valve ports will tee with the orbital under the Cab oor panel.
The LS line from the FieldPilot valve will Tee with the Orbital LS via shuttle tee where the branch of the tee
returns to the Priority Flow Control valve on the tractor. Again, this is under the cab oor panel. The A and B
lines from the FieldPilot valve will tee in the front of the tractor at the steering cylinders. The connections will
be as follows:
FieldPilot – Orbital
T – T
P – P
A – L
B – R
LS – LS
1. PrePare the FieldPilot ValVe
Install adapters (S) in the B and LS ports. Install adapters (T) in the A, P, and T ports. Attach tting (X) to
the adapter (T) in the A port.

3. install the FieldPilot ValVe Bracket
The valve bracket will mount to the vehicle’s frame on the left side. Using the existing hole just below the
Engine Oil Cap, mount the (K) bracket with (1) (H) 5/8” bolt, (1) (J) 5/8” nut and (2) (F) 5/8” washers.

4. Mount the FieldPilot ValVe
Mount the FieldPilot Valve to the (K) bracket using parts (B, G & I). Mount it so the P and T ports are
pointed toward the cab and the A and B ports point away from cab. The solenoids should be on the bottom.
Figure 1-5: Mount the FieldPilot Valve
5. PrePare For connection to orBital ValVe
The connections to the orbital are done under the oor panel in the cab. Remove the rubber oor mat.
Remove the metal cover. For ease of visual identication, colored tape was used.
Blue = Left
Black = Right
Green = Tank
White = Load Sense
Red = Pressure.
Disconnect the pressure line and attach the (U) Run Tee to the steel line. Reconnect the pressure hose
to the end of the run. The branch of the tee should point to the left and down. Repeat the above steps
for the Tank line. It also uses a (U) Run Tee. Disconnect the Load Sense line. Connect the hose end to
the Branch of the Shuttle Tee. Connect one end of (L) hose to the adapter from the run of the Shuttle Tee
pointing to the rear of the tractor and the other end of (L) hose to the steel line.

The steering hoses will connect to run tees installed at the front steering cylinder. Disconnect the left side
hose from the inline Tee. Attach the run of the new (U) Tee to the branch of the existing Tee. Reconnect
the existing hose to the run of the (U) Tee. Connect the (P) 90° hose end to the branch of the (U) Tee.
Connect the straight hose end to port A on the FieldPilot valve. Disconnect the right side hose from the
inline Tee. Attach the run of the new (U) Tee to the branch of the existing Tee. Reconnect the existing hose
to the run of the (U) Tee. Connect the (Q) 90° hose end to the branch of the (U) Tee. Connect the straight

11. install steering disengage switch (kit 91-07011)
The steering disengage kit (Z) is used to automatically disengage FieldPilot when the steering wheel is
turned. The magnets mount on the steering shaft or other rotating part of the steering wheel and the sensor
mounts so that there is a 1/8″ clearance between the sensor and magnet.
Figure 1-11: Install Steering Disengage Switch (Kit 91-07011)
12. 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.

The Steering Control Module (SCM) should be mounted securely to the oor of the cab as far forward in the
cab as possible. The control console can be mounted to the operator’s preference. The GPS antenna should
be mounted as far forward as possible on top of the cab on a metal surface of at least 4″ square.

14. 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.
The nal oil ow rate adjustment is accomplished through the Matrix 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 position of 1 turn 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
approximately 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.
