4 INSTALLATION PROCEDURE
4.1
EXISTING SYSTEM CHECK
It is necessary to check the existing system’s
functionality before installing the UC4+ Spray
Height Control.
You will need a stopwatch or a watch
that displays “seconds” for the next
step.
1. Drive your sprayer onto a flat piece of land,
with unobstructed boom movement (e.g. no
power lines).
3. Raise the LEFT boom from its extreme
LOW position to the very TOP of its travel.
Record the time this takes in Table 6, “Trial
#1” for “Left UP”.
2. Test that all boom functions operate
correctly. As you test each function check it
off in Table 5.
It is necessary to test the boom
functions in all directions

BOOM SPEED TEST
IMPORTANT:
Raise/lower all boom sections several
times to warm up the hydraulic system.
Grease all moving parts for consistent
results.
1. Lower each boom and main section as close
to the ground as possible.
4. Lower the LEFT boom from its extreme
HIGH position to the BOTTOM of its travel.
Record this time in Table 6, Trial #1 for
“Left DOWN”.
Be careful when lowering the booms
so they don’t hit the ground.
5. Similarly, record two more time trials (Trial
#2 & #3) for the LEFT boom and record in
Table 6.
6. Repeat Steps 1 through 5 for the RIGHT,
MAIN and ROLL functions.
Your sprayer may not have a roll
feature.
7. Average the three trials recorded for each
boom movement and record this calculation
in the “Average Time” slot in Table 6.
8. These “Average Times” now represent how
quickly your system can react to manual
control. In Section 4.9, this procedure is
repeated with the UC4+ Spray Height
Control installed for comparison and
troubleshooting purposes.
2. Set your sprayer at field working RPM on
the throttle and mark this value in Table 6.

WING SENSOR INSTALLATION
1. Mount the Low Profile Sensor Mounting
Brackets (B20) onto the boom as show in
Figure 4 and Figure 5 with the mounting
base in front of the tube.
If possible, mount the sensor
brackets while the booms are in their
folded position to ensure that they
will not interfere with anything when
the boom is folded for transport.
Mounting the sensor bracket to the
break-away section of the boom may
cause the boom to drop suddenly as
a break-away occurs. This will occur
on break-away sections which lift as
they break away.
For optimal boom tip protection, it is
recommended that the sensor be
mounted within approximately two
feet (60cm) of the boom tip.
Figure 4: Low Profile Bracket Mounting
Please refer to the UC4+ system warranty
at the end of the UC4+ Sprayer Boom
Control Operator’s Manual (M01) for
implications.
2. Mount the NORAC UC4+ ultrasonic
sensors (E02) into the sensor brackets. The
sensors should be oriented forward (ahead)
of the boom.
Front
Figure 5: Low Profile Bracket Mounted on
Boom
When installing the UC4+ sensors
(E02), start with the smallest serial
number on the left hand side
proceeding to the largest serial
number on the right hand side
(Figure 9).
3. Sensor cables should run either through
hole in the back or through the side cut-out
and behind the bracket. Ensure the cable is
clear of moving parts and will not be
damaged during folding.
Cable-tie the
connector in place. The cable must not hang
below the boom
12
Exhaust clamps (B16) can be used if
mounting the sensor brackets to a
portion of the boom with round
tubing.
General Mounting
Ultrasonic Sensors:
Rules
for
UC4+
a) In its lowest position, the sensor must be 9
inches (23 cm) or more from the ground.
b) Ensure that there are no obstructions within
a 12-inch diameter circle projected directly
below the center of the sensor.
c) The sensor should be approximately vertical
at normal operating heights.
Front
Figure 6: Low Profile Bracket Mounted
with Exhaust Clamps
General Mounting Rules for Low Profile
Brackets:
a) Minimize the distance between the bolts to
prevent bending the bracket and prevent the
bracket from loosening over time.
b) Ensure the bracket is mounted tight against
the bottom of the boom, minimizing the
distance between the boom structure and
the angled flange.

TARGET INSTALLATION AND ALIGNMENT
NOTE: It is very important that the
rods be installed on the right hand
side of the sprayer.
The sprayer must be level when
installing the UC4+ Roll Control
System.
The sprayer booms
should be level as well, parallel to
the sprayer’s lift frame.
1. To ease the installation of the UC4+
Roll Control system, unfold the sprayer
on a level area and lower the center
section to three or four feet above the
ground. A ladder or step will also be
required to complete the installation.

2. Remove the rubber bumpers on both
ends of the roll frame (Figure 16).
3. Install the frame target (B09) onto the
parallel lift frame. The mounting bolt
should be close to the vertical member
of the frame facing forwards. See Figure
15 and Figure 16.
4. The frame target should be 41” (104cm)
from the bottom of the sensor as
shown in Figure 18.
The frame target (B09) should be
mounted to a frame member
that does NOT rotate with the
boom.
5. Install the spring target (B12) onto the
boom center section 16” (41cm) down
from the bottom of the sensor as
shown in Figure 17.
The spring target (B12) must be
mounted to a frame member

not interfere with folding.
7. Install the roll sensor bracket on the Tshaped black intermediate frame, as
shown in (Figure 17). The required
mounting hardware is included with the
bracket.
The sensor should not be behind
the wheel.
The bracket rod is designed to
slide in the bracket collar to
allow for sensor alignment
required in Step 8.
The sensor should be mounted
between the parallel lift arms and
Figure 18: Roll Sensor Mounting
Bracket

8. Adjust the targets and sensor bracket
using a 4-foot level or a plumb line. The
goal of this step is to have the sensor
bracket and both targets in the proper
locations. The proper location of the
targets are as follows:
bracket. Check each target and
compare them to the proper location.
See Figure 17.
i) Spring target on the centerline of
the sensor.
ii) If both targets are to one side of the
plumb line, adjust the location of the
spring target bracket using the
adjustable ball and socket mount.
ii) Frame target ½" to the left side of
the centerline.
Ensure the sprayer is level AND
the booms are level when
installing the roll targets.
9. Hang a plumb line down the center of
the sensor mounting hole of the sensor
i) Ensure that both the roll and spring
targets are perpendicular to the
sensor.
iii) The frame target can be adjusted by
sliding the bracket along the parallel
lift frame. This target should be
located ½" off the centerline.
Spring Rod trimmed 1”
past edge of sensor.
Figure 19: Target Rod Alignment (Side View)
10. When the target positions are correct
ensure all mounting bolts are tight, then
double-check the target locations to ensure
that they haven’t drifted out of position.
Some adjustment of the Sensor Roll
Bracket may be necessary to achieve
proper alignment.
11. Once alignment is correct, trim the top rod
so it is 1 inch past the edge of the sensor, as
shown above in Figure 19.

HYDRAULIC INSTALLATION
IMPORTANT:
WARNING!
The hydraulic system creates very
high pressure. Before disconnecting
any hydraulic lines ensure all pressure
has been bled from the system.
When changing the boom hydraulic
hoses
leave
the
booms
in
TRANSPORT POSITION.
Component failure due to oil
contamination is not covered under
the UC4+ Spray Height Control
system warranty. It is recommended
that a qualified technician does the
hydraulic installation.
4.7.1 Roll Cylinder Installation
1. Remove the link arm (black square
tube) connected between the parallel lift
frame and roll frame. See Figure 21
for the link arm location.
2. Install the roll cylinder (H75) in place of
the link arm (Figure 22). When doing
this the top pin in the link arm must be
replaced with the supplied pin (B18).
The snap ring on the existing pin can be
used.
3. Install the 6MB-6MOR (F12) fittings
into the cylinder.
4. Install the 4MOR-4FORX90 (F14)
fitting onto the cylinder fitting at the cap
end of the cylinder.
5. When the cylinder is installed the
bottom bolt must be tightened to 266
ft-lbs (350 Nm) and there should be no
slop or free-play on the bottom bolt or
the top pin. Any free movement will
drastically reduce the active roll
performance.

In several cases, the lower cylinder
mount on the roll control hydraulic
cylinder has failed.
In the
documented cases, the bracket has
failed at the weld shown in Figure 23.
It is recommended that all sprayers
with roll control add weld to the
existing bracket to prevent failure.
Some sprayers from 2005 and newer
already have gussets added at the
factory.

4.7.2 Valve Mounting
1. On a clean surface remove all plastic plugs
from the NORAC hydraulic Valve (V01).
2. Install the 6MB-6MOR fittings (F05) on the
"P" and "T" ports and tighten to 18 ft-lbs.
3. Install the 4MOR-4MB (F06) into the "S"
port and tighten to 11 ft-lbs.
Figure 26: Valve Block Assembly
9. Mount the 6MB-4MOR fittings (F12) into
the “A” and “B” ports on the NORAC 3rd
station block.
Figure 25: NORAC Valve Block
4. Install two orifices (F08) into the "B" ports
with the notch facing outward as shown
in Figure 26.
5. Install the remaining orifices (F08) into the
"A" ports with the notch facing inward
as shown in Figure 26.
6. Install the 6MB-4MOR fittings (F07) into the
"A" and "B" ports and tighten to 18 ft-lbs.
7. Insert the 0.047” orifice (F07A) into the “B”
port of the 3rd station of the block with the
notch facing in (Figure 27).
8. Insert the 0.042” orifice (F07B) into the “A”
port of the 3rd station of the block with the
notch facing in (Figure 27).
Figure 27: Orifice Orientation
4. Remove the plug from the Sense Line Bleed
port. Location is shown in Figure 28.
Gently tap the plug with a hammer to loosen
it before attempting to remove it. To access
bleed orifice, remove the valve coil that is
covering it, by unscrewing the nut on the
coil. Remove the Sense Line Bleed Orifice
and discard.
22
5. Install the setscrew (F11) into the Sense
Line Bleed Orifice location. Ensure the
setscrew is threaded entirely into the hole
and tightened to 35-40 in-lbs to ensure a
tight seal. Reinstall the plug and tighten to
35-40 in-lbs.
Remove
this coil
16. Cut excess off of the rods, if necessary.
If you wish to use bolts, the bolts
should thread into the valve block at
least 3/8". The valve mounting holes
are drilled and tapped 3/8 NC-1"
deep. The rule of thumb for bolt
length is 1-1/2" longer than the tube
size.
The recommended location for the
valve is on the angled cross tube of
the parallel linkage on the sprayer.
Orient the valve block so the "A" and
"B" ports face towards the boom
(Figure 30).
You must ensure no hydraulic
components will interfere with any
sprayer parts or be pulled tight at
any time.
Figure 28: Load Sense Bleed Orifice
Location on Top of Block
10. Mount the NORAC valve (V01) on the
sprayer using the valve mounting bracket
(B10).
11. Thread a nut onto the short threads of each
of the threaded studs.
12. As shown in Figure 29, screw the short
side of the threaded rods into the bottom of
the valve block and tighten the hex nuts tight
to the valve block.
Figure 29: Valve Mounting Location
13. Place the valve block onto a frame member,
with the studs extending to the other side of
the member.
14. Slide the flat bar from the bracket over the
studs and install a spring washer and nut
onto each of the studs to hold the bracket in
place.
15. Tighten the two nuts so the valve block is
held on tight and cannot move.

fitting (F10) in the “T” port of the NORAC
valve block.
8. Tee the hoses, H02 (“P” and “T” lines), into
the ports on the sprayer valve block with
6FORXR-6MORT fittings (F03) and 6MB6MOR fittings (F05). The elbow fittings
currently in place must be replaced by the
6MB-6MOR fitting (F05). The “P” and “T”
lines are located on the left side of the John
Deere valve block.
9. Connect the free end of hose H02, installed
at the JD “P” port, to the tee on the “P”
port of the NORAC valve block.

16. The existing hoses that run to the boom tilt
cylinders should be disconnected from the
sprayer valve block and reconnected to the
NORAC valve block.
a) The “raise” lines must be connected to
the "B" ports of the NORAC valve block.
The ports on the sprayer block must
then be capped with 4MBP plugs (F09).
b) The "A" ports of the NORAC block
must be connected to the “lower” lines
of the cylinders. The ports on the
sprayer block must then be capped with
F09.
Most John Deere Sprayers have
orifices in the "A" and "B" lines of
the boom tilt cylinders. To remove
the orifices you must remove the
fitting from the cylinder. The orifice
is directly beneath the fitting.

and tee in accordingly.
17. Tee the Load Sense line (H06) directly in to
the port “S” of the shuttle valve manifold
using fitting F03 as shown in Figure 34,
Figure 35 or Figure 36.
On some installs the Load sense hose
(H06) may be too long and the
excess hose must be coiled and
secured where it will not interfere
with other components.
There are multiple versions of JD
load sense blocks on sprayers.

ELECTRICAL INSTALLATION
1. Install the UC4+ Control Panel (E01) in the
cab of the sprayer. Mount the panel where
it will be clearly visible and within easy reach
of the operator.
ROP
ROP
A good spot to mount the UC4+ control
panel is on the right hand side of the cab to
the Roll Over Protection Bar (ROP). Four
pilot holes for the screws provided need to
be drilled to facilitate the control panel
mounting.
If desired, a mounting bracket (part
#A53255) can be purchased from your local
John Deere dealer to allow the UC4+
control panel to be mounted to the existing
John Deere terminal mount.
Another
option is to purchase an adapter for the
flexible panel mount that has a 3/8" NC
threaded stud on the end to bolt through
the existing JD mount. You can find these at
your local outdoor store as a RAM mount
part
number
RAM-B-236.

2. Connect the UC4+ power cable (C10) and
sensor trunk cable (C01) to the UC4+
Control Panel (E01) (see Figure 40).
Ensure the UC4+ Control Panel’s
power is OFF for the remaining
installation.
(Bottom of switch
pressed IN).
3. Plug the 3-pin connector on C10 into the
cab’s power bar.
4. Route the free ends of C10 and C01 along
the side of the cab post and under the floor
mat.
6. Plug in the 6-pin Tower on C10 to the 6-pin
Shroud on the valve extension cable (C04).
C04 comes with one connector
(M16) unassembled to allow the
cable to be run through a hole in the
floor under the steering column. To
assemble this connector (M16), refer
to the drawing in Section 5.4. The
pins require a special tool to remove
them if you make an error.
The cables may also be routed
through the rear window of the cab.
7. Route the free ends of C01, C04 and C70
to the rear of the sprayer near the sprayer
valve block. Run the cables along the
sprayer frame with the JD harness.
Figure 41: Hole under Floor Mat
5. Plug the 2 pin tower on C10 into the 2 pin
shroud on the roll bias cable (C70).
31
The hole in the floor may be covered
by a plate, or a grommet may be
installed in the hole. They can be
reinstalled after the wiring is
complete.
NORAC supplies a
grommet (M13) for the hole if one
does not exist.
Figure 42: Cable Configurations: C12, C03, C04 and C70
8. Connect the 6-pin Shroud on C04 to 6-pin
Tower on the junction cable (C12) (Figure
42).
9. Connect the 6-pin Tower on the valve cable
(C03) to 6-pin Shroud on C12.
10. C12 and C70 have screw terminals. They
must be connected to the frame of the
sprayer Scrape any paint off the frame where
the terminal is mounted. A good location is
the bolt holding the JD wiring harness next
to the large connector at the rear of the
sprayer frame.
The terminal must be attached
directly to the sprayer frame NOT
the parallel linkage. An improper
ground can cause UC4+ Spray Height
Control malfunctions.
11. Insert the connectors labeled Main Up and
Main Down on C12 into the main lift
connectors on the John Deere solenoids
(Figure 43).
12. Insert the other connectors on C12 into the
tilt connectors on the John Deere solenoids
(Figure 43).
There is one set of different connectors
(M14 and M15) included with the interface
cable (C12). Some John Deere sprayers
use this connector on the left down
function.
If your sprayer has this
connector, remove the existing NORAC
connectors using the included pin removal
tool.
Insert the wires into the new
connector and ensure they are in the
same position as they were in the
previous connector.

COMPLETING THE INSTALLATION
1. Start up your sprayer and test the sprayer’s
functionality. The NORAC Control Panel
does not need to be powered up for the
original switches to function. Unfold the
booms and raise/lower each boom and main
section.
Again confirm that the cabling/hoses
are agreeable to the entire range of
motion.
2. If any functions do not work, review the
hydraulic and electrical portions of this
manual to check for proper installation. If
you still have trouble, contact NORAC for
assistance.
If the roll direction is opposite to
your preference when pressing the
switches, you may reverse the
direction by swapping the connectors
on the 3rd station block.
3. Turn on the power for the UC4+ Control
Panel using the switch on the side of its
chassis.
4. Repeat the Boom Speed Test as described in
Section 4.2 Boom Speed Test with the
NORAC UC4+ Spray Height Control
installed. Record the results for comparison
in Table 7.
5. The procedure for the installation of the
UC4+ Spray Height Control is now
complete. Begin the AUTOMATIC SYSTEM
SETUP procedure as described in the UC4+
Spray Height Control Operator’s
Manual (M01).
35
4.10 SYSTEM MAINTENANCE
For good performance in corners, when driving
over terraces or through ditches at an angle, or
in hard steer situations it is important to do the
following:
1. The Teflon sliding pads on the boom must
not grab in dynamic situations (corners,
terraces etc). See the photos below for the
location of the sliding pads. Apply grease to
the complete surface of all sliding pads.
Manually rotate the boom (by pushing on
the ends) to access the entire surface of the
pads when greasing.
2. Check that the pin in the top of the cylinder
is not loose and does not have any free
movement or slop. The bottom cylinder
mounting bolt torque must be checked
regularly. The bolt must be tightened to 260
ft-lbs (350 Nm).
Figure 48: Upper Front Sliding Pad
3. Ensure the sprayer operator continues this
maintenance for proper operation.
It is recommended that the pads be
re-coated with grease every 20 hours
of operation.

APPENDIX A - INTERFACE CABLE MODIFICATION PROCEDURE
Some earlier models of John Deere sprayers
(4700 and 4710) may use a different style of
boom valve block with a different arrangement
of the connectors. As a result, the NORAC
44658-01 interface cable (C12) will need to be
modified according to the following instructions
(See Figure 50 and Figure 51 for before and
after schematics):
1. Using the supplied GP Weatherpack pin
tool, carefully remove the blue/black wire
tee (Main Down) from the A-position of the
4-pin flat connector tee (S4B & T4B). The
blue wire is attached to a black wire that
goes across the tee connection (remove
both ends of this tee).
2. Insert blue/black wire tee from step 1 into
the A-position of the 6-pin flat connectors,
M14 and M15 (S6C & T6C), that are
supplied in the zip lock bag with the cable
(these connectors are keyed on the A and F
position).
3. Locate and remove the green wire (Left Up)
from the A-position of the 6-pin flat shroud
(S6B). Also remove the 5 black wires from
this tee (S6B & T6B). Use these 5 wires to
tee the remaining positions of the two 6-pin
connectors (S6C & T6C) used in step 2
together (BB, CC., DD… etc).
Remove the cavity plug from the A-position
of T6B for use in step 4. After this step,
there will be 2 unused 6-pin flat connectors.
4. Remove the black wire that goes across the
connection in the A-position of the 4-pin
square tee with the red wire (Right Up) in
the C-position (S4C & T4C). Insert the
green wire (Left Up) from step 3 into the A-
position of the 4-pin shroud (S4C). Seal the
A-position on the 4-pin tower (T4C) with
the cavity plug removed in step 3.
5. Locate and remove the brown wire (Left
Down) from the A-position of the 6-pin flat
shroud (S6A). Remove the black wire that
goes across the connection in the A-position
of the 4-pin flat tee with the white wire
(Right Down) in the C-position (S4D &
T4D). Insert the brown wire (Left Down)
into the A-position of the 4-pin shroud
(S4D). A cavity plug will be removed in step
6 that may be used to seal the empty cavity
created when removing the black wire from
the 4-pin flat tower (T4D).
6. Locate and remove the black wire (Main Up)
from the 4-pin square connector tee (S4A &
T4A). This black wire is attached to a black
tee wire similar to the wire described in
step 1. Insert black wire into the A-position
of the 6-pin flat assembly removed in step 5
(S6A & T6A). This will require removing the
cavity plug installed in the A-position of the
6-pin tower (T6A). The cavity plug can then
be used to seal the empty socket created in
step 5.
7. The cable modifications are complete.
There should be 2 unused 6-pin flat
connectors, 2 black wires, an incomplete 4pin square tee and an incomplete 4-pin flat
tee left over.
8. Connect the modified harness to the sprayer
as indicated in Figure 52.
