SPECIFICATION
GENERAL INFORMATION
The 8000 series cane harvesters utilizes an 9L (8.7L) engine built by Iveco to provide the
required power, performance, fuel economy, torque rise, and power growth that today’s
customers demand. The engine is a six cylinder turbo charged and air-to-air after cooled
diesel engine.
The engine uses an electronically controlled high pressure common rail fuel system, with a
cam shaft controlled EGR operation to meet current emission regulations. A high pressure
pump is used to charge and maintain pressure in the common rail, and solenoid operated
injections are used to determine timing and fuel metering to the engine. Any CaseIH
authorized servicing dealer must service the engine.
MAJOR FEATURES:
Full-Authority electronic fuel injection engines using a turbo charged air to air
charge air cooler to provide the required performance.
Four valves per cylinder increase the movement of air into the combustion chamber
and exiting into the exhaust, resulting in improved performance and efficiency.
A rated speed and rated power at 2100 RPM improves fuel efficiency, reduces
noise and provides for overall reliability and durability of the engine.

Current ECU Data Set
Normal fuel usage will vary with field condition, so it will not be possible to give a customer an
expected recommendation. It has been determined that usage around 1L/Ton of cane cut
would be a very good rate, but may go up from there.
GENERAL INFORMATION
This data is constantly compared to normal parameters and alerts the operator if a problem is
detected. These faults are stored in memory and displayed on the display unit. If service is
needed, these fault codes guide the service technician through the repair process.
The system uses Bosch CRIN 3 injectors and a Bosch CP3.3 high-pressure fuel pump. The
control system provides variable timing, high-pressure fuel control and a constant engine
speed feature.
ENGINE EXPECTATION
It is expected, in todays market and with the current level of fuel prices, that as much tonnage
of crop be cut while using the least amount of fuel. This reduces the overall operating
expense for the crop.
In most areas the expectation is to cut one ton of crop while using no more than one liter (1.05
qt) of fuel. To meet the challenge, the 8800 series cane harvester is equipped with a 9L
engine that provide power and performance, a unique software package that permits the
operator to fine tune the machine performance and fuel consumption to meet the crop’s
demand.
While using the cab display unit, the operator may selected one of the following operating
Power Curves by Navigating = Toolbox>Engine – Power Curve
• High Power Curve
• Low Power Curve
• Smart Cruise, High Power Curve
• Smart Cruise, Low Power Curve
Wait a Minute…Is this operation only available on the 2012 machines? NO the
current software may be loaded into any 8000 series sugar cane harvester.
REMEMBER: To make changes to the settings, the Power Curve password will be
required.
Other settings that will be used with this operation will be the “High Idle, Intermediate and Low
Idle engine speeds.
High Idle: The high idle will be one of three pre-programed speeds:
1800 RPM, 1850 RPM or 2100 RPM.
The speed may be set between 1200 – 2000 RPM. Select a speed that permits good
performance during headland maneuvering, BUT still low enough to conserve fuel.
REMEMBER: Disengaging the harvesting unit may also provide fuel savings.
If the Low setting is selected and the machine is overloaded, it will NOT revert back to the
High power setting. The operator may change between the two setting as often as condition
require.
REMEMBER: High idle will be set to 2100 RPM for either power curve.
Change Password
Using the cab display, navigate: BACK>TOOLBOX>ENGINE-Power Curve. The operator will
be required to enter the current password at this time. Once the password is entered correctly
and the enter button pressed, a message will be displayed instructing the operator that the
password was correct and that it could be changed if desired.
The difference with Smart Cruise is that the engine will not always be operating at 2100 RPM.
High idle will vary between 1800, 1850 and 2100 RPM automatically, depending on conditions.
Also the intermediate speed may automatically be reduced to 1200 RPM under certain
conditions. These operation further increase fuel savings.
INPUTS
Below is a table of condition:

INFORMATION FLOW
The engine communications, controls and monitoring functions are split between several
controllers. The engine control unit is in complete control of the engine performance, but
considers inputs from various other controls and sensors.
These increments may be present at different levels through the configuration; also, once the
switch has been pressed and WHILE the engine is increasing or decreasing and the switch is
pressed a second time; the engine will remain at the speed when the switch was pressed
again.
The sensor is provided a 12V supply at terminal 2 from the RHM. The sensor’s terminal 1 is
connected back to the RHM connector KN1-B10 for a speed INCREASE. The sensor’s
terminal 1 is connected back to the RHM connector KN1-B09 for a speed DECREASE.
Location: Located in the right hand console
SCM2
Coolant Level Sensor, SW-29
The coolant level sensor will monitor the coolant level in the overflow tank, if the sensor should
loose contact with coolant it will close. The switch directs a signal to the SCM2. Low coolant
level will signal a priority 2 alarm.
The switch is supplied 5 volts from the SCM2’s connector C201-21 to the sensor’s connector
C067-A. The switch is supplied a reference ground at connector C067-B back to the SCM2 at
C201-3.
Location: Located in the over flow tank

SCM2
Air Filter Restriction, SW-030
The air filter restriction switch is used to monitor the condition of the air filter. Should the filter
become too restrictive approximately 60 mbar (24 inches of water) for efficient engine
performance the N/O switch will close, directing the circuit to the chassis ground.
A __V supply provided by the SCM2 connector C202-36 is directed to the filter switch SW-030
terminal C068-1 and a chassis ground is supplied to the switch at C068-2. As long as the filter
restriction is low and the switch is OPEN (N/O) the voltage on the signal wire will remain at
supply voltage.
Location: Located at the outlet of the air filter canister

CCM2, CON’T
Engine Oil Pressure / Temperature, B-75
The Engine oil pressure sensor is used to monitor the engine oil pressure. If the engine oil
pressure should drop below 14 PSI (1 bar) for 3 seconds a priority 2 alarm will be activate. If
the pressure should remain below this setting for an additional 7 seconds a priority 3 alarm is
activated and the engine will shut down. If the engine is restarted and the pressure is still low
the engine will shut down in 30 seconds.
The Oil Temperature sensor is used to monitor the engine oil temperature. If the temperature
should climb above 258 deg F(126 deg C) for 3 seconds a priority 2 alarm will be activate.
When above 266 deg F (130 deg C) a warning message is activated and a priority 3 alarm is
activated and the engine will shut down. If the engine is restarted and the temperature is still
high the engine will shut down in 30 seconds.
The sensor is supplied 5V from the ECU connector X516 terminal 32 at the senor terminal 3.
The sensor is provided a reference ground at terminal 1 from the ECU connector X516
terminal 24.
Pressure
The ECU monitors the variable voltage signal from the sensor at connector X516 terminal
27.
Temperature
The ECU monitors the variable voltage signal from the sensor at connector X516 terminal
28.
Location: Above the engine oil cooler
ENGINE COMMUNICATIONS
The ECU monitors inputs that other controllers on the data bus, monitors engine operations,
place engine information on the data bus and control the engine fuel system.
The engine control unit determines and controls the timing and volume of fuel delivered to the
engine. A heat exchanger mounting pad cools the unit. The fuel from the electric transfer
pump flows through the heat exchanger, cooling the control unit.
Using the EASY program (in the EST) ECU software may be installed and/or updated; a
password may have to be requested using the ASSIST system before the software may be
loaded. The software in the control unit is capable of producing full rated horsepower; it is the
CCM2’s software that commands the ECU to use the standard power curve (Power Rise) or
the unloading power curve (Power Boost).
The ECU will provide fault codes that may assist the technicians with troubleshooting.
The ECU supplies a 5 volts from connector X516 terminal 35 (which is the signal wire) to the
sensor’s terminal 2. The sensor’s terminal 1 is connected back to a common ground at the
ECU terminal 17. As the fuel temperature increases, the resistance of the sensor decreases,
causing the supply voltage to decrease.
Location: Refer to previous component listing in this section
ENGINE COMMUNICATIONS
ENGINE CONTROL UNIT, (ECU) A-01
Coolant Temperature, B-44
The Coolant Temperature sensor monitors the engine temperature. If the coolant temperature
should climb above 215oF (102oC) for 2 seconds a priority 2 alarm will be activated. If the
temperature climbs above 239oF (115oC) for warning message will be activated. If the
temperature stays above 239oF (115oC) for 2 seconds a priority 3 alarm will be activated and
the engine will shut down. If the engine is restarted and the temperature is still high the engine
will shut down in 30 seconds.
When the coolant temperature is above 215oF (102oC) the controller will reduce the fuel flow,
reducing the power output.
The ECU connector X516 terminal 15 supplies a 5V power supply to the temperature sensor
terminal 1. The sensor’s terminal 2 is connected back to the ECU terminal 26. As the
temperature of the coolant increases, the sensor’s resistance decreases, placing a larger
current draw on the supply from the ECU.
Location: See picture on page 11-10
The ECU connector X516 terminal 19 (which is the signal wire) supplies a 0.25V power supply
to the crankshaft sensor terminal 1. The sensor’s terminal 2 is provided a return ground to the
ECU connector X516 terminal 23. A signal is generated as the gear on the flywheel passes
the sensor.
Location: Located on the lower left center of the block (behind oil filter)
ENGINE COMMUNICATIONS
ENGINE CONTROL UNIT, (ECU) A-01, CON’T
The engine cam gear sensor (B-07) is used by the ECU to monitor the engine speed and to
provide for cam position to determine fuel timing. Once engine RPM increases above 50
RPM, the ECU will permit the engine to start. If the sensor has failed, the ECU will use the
flywheel sensor to determine TDC; at which time a small amount of fuel will be injected into
number one cylinder and when it attempts to fire (learning compression stroke) the flywheel
sensor will pickup the increased RPM and let the engine start. Power will be reduced.
The ECU connector X516 terminal 9 (which is the signal wire) supplies a 0.25V power supply
to the cam sensor terminal 1. The sensor’s terminal 2 is provided a return back to the ECU
connector X516 terminal 10. As the cam gear passes the sensor, a signal is generated.
Location: Located on the right side of the cam gear housing
The intake manifold temperature sensor (IMT) is used to monitor the efficiency of the Air-to-Air
cooler and to provide a signal for the cold weather starting grid. When the air temperature is
above 150oF (65oC) the controller will reduce the fuel flow, reducing the power output.
The sensor is supplied 5V from the ECU connector X516 terminal 33 at the senor terminal 3,
the sensor is provided a reference ground at terminal 1 from the ECU connector X516 terminal
25.
Pressure
The ECU monitors the variable voltage signal from the sensor at connector X516 terminal 34.

The CCM2 supplies 5 volts from connector X016 terminal J2-36 (which is the signal wire) to
the sensor’s terminal B. The sensor’s terminal A is connected back to a common ground at
the CCM2 connector CCM2 X016 terminal J2-14. If the switch closes for 5 seconds, an alarm
will be activated. The switch is a normally open switch, closing at a 22 psi differential
pressures.

CRANKING
FUSES
The unit incorporates two fuses to protect the system. If the contacts inside the relay fail to
activate in the correct sequence either battery could be short-circuited, if this should happen
one of the fuses would blow to protect the system.
Fuse 1: Fuse number one protects the B+ side of the circuit. It prevents 24V from
entering the main electrical system, directing it to the starter solenoid only.
If it fails the relay will close, BUT 24V will not be directed out terminal 50 to the
starter solenoid. The relay will click once.
Fuse 2: Fuse number two protects the B- side of the circuit. It prevents the front battery
from a direct short.
If it should fail the 12/24V relay will loose its ground through terminal 31, it will
only close momentarily. The relay will chatter.
STARTING
REFERENCE SCHEMATIC FRAMES:
Frames: #1, 2,
Power is also directed to relay RLY19-3 from fuse F-06. The relay is provided a chassis
ground at terminal 2.
STARTING
Key Switch “RUN”
When the Key Switch is placed in the RUN position, power is directed out connector C40:
SCM2: will be powered up. It will be the responsibility of the SCM2 to perform the
actual engine starting process.
REMEMBER The Grid Heating operation is automatically controlled by the ECU, the
operator should give the heating process at lest 15 seconds before attempting to crank the
engine.
Terminal 5 from relay RLY-19 is directed to the12/24v relay at terminal 50A. With the
12/24v Relay activated, the 12V supply from the inside battery BAT-01 POS post at
terminal 30 is directed out terminal 31A to the NEG post of the outside battery BAT-02
to create 24V. The POS on the outside battery is connected to the Starter Solenoid B+
post. 24V power is also directed out terminal 50 to the Starter Solenoid terminal S to
activate the Solenoid, cranking the engine. The connection between 31A and 31 is
also opened.
ENGINE MONITORING
The engine operation is monitored and controlled by the ECU and the CCM2; messages are
placed on the data bus for the Cab Display unit to display.

Using the EASY tool log the actual data using the graph option and attach the file to an assist
when requesting assistance.
ENGINE LOAD
Use the display RUN screen to monitor the engine power. This is an indication of the amount
of fuel delivered to the engine. A normal reading will be 100% before the engine speed begins
to drop below 2100 RPM, and when loaded should climb to approximately 105% when NOT
unloading. While unloading on the go the power % may increase to approximately 117% level.
COOLANT TEMPERATURE
When coolant temperature increases above 102oC / 215oF the engine control unit can reduce
the fuel delivery.
BOOST PRESSURE
Boost Pressure is a measurement of the pressure that is being created by the turbo charger.
The ECU uses this information in determining fuel delivery. It has been experienced that an
injector can prevent the boost pressure from reaching the target pressure. Intake pressure
should increase to 50-52 PSI (3340-3580 mbar) when the engine is under full load.
FUEL TEMPERATURE
Wait a Minute… What is the Engine Load display telling me? The reading is
an indication of the power being consumed compared to the rated power. (The length
of time the nozzles are injecting fuel into the cylinder by monitoring the solenoids duty
cycle.) This provides an indication of load.
FUEL SUPPLY
STEP 2: FUEL SUPPLY
FUEL SYSTEM RESTRICTION TEST
System restriction can be determined by the following test procedure. Use the following steps:
“EST” SCREEN
Boost Pressure is easiest monitored with the EST using the parameters found under
the CCM2. The EST reports the boost pressure in what is call "absolute pressure" it
includes the 14.7psi (1bar) of atmospheric pressure. Remember to reduce the reading
by 14.7 to get the actual boost increase reading.
Wait a Minute… So how am I suppose to understand and use this reading for
proper diagnostic work?
WHAT IS A BAR
A bar is a measurement based off the atmospheric pressure. Atmospheric pressure is
normally 14.7 psi, so 1 bar equals 14.7psi.
Example: 2675mbar = 2.675 bar so 2.675 bar X 14.7 psi = 39.3 psi.
FINAL READING
The measurement is displayed in ABSOLUTE PRESSURE, which means that it is including
the normal atmospheric pressure with the boosted pressure. For this reason, we will have to
reduce the displayed reading by one atmospheric pressure.
Example: 2675mbar = 2.675 bar 2.675 X 14.7 = 39.3 psi, (this is absolute
pressure) that must be reduced by one bar to get to actual boost pressure
2.675 bar – 1 bar = 1.675 bar actual boost
Actual boost = 1.675 bar X 14.7 psi = 24.6 psi
A second key item is to monitor the duty cycle of the pressure regulator. The regulator is
supplied PWM and the duty cycle will vary depending on the engine load. Remember that the
regulator is a normal OPEN valve, to limit fuel pressure the valve must be closed; because of
this the duty cycle may be just the opposite as expected. The more fuel required to maintain
the pressure - the lower the duty cycle required.
If a reading remains below ~27% for an extended period of time a fault code will be generated.

4. Install the camshaft gear; verify the camshaft gear is orientated as shown above.
Position the camshaft gear so the slotted holes are close to centered. Install the four camshaft
gear retaining bolts and tighten (bolts do not need to be tightened to specified torque yet as a
final timing adjustment may be needed).
Install rocker arm assembly and tighten rocker arm assembly to specified torque.
Rotate engine clockwise until the "D" hole (the hole with two notches) passes the window (10°
to 20° past) in the bottom of the flywheel housing. Rotate the engine back counterclockwise
until the "D" hole is on the window and the timing pin will lock the flywheel through the sensor
hole. This removes the back lash from the gear train.
5. Install a dial indicator on the #3 exhaust valve rocker arm camshaft roller as shown.
Preload the dial indicator 6.0 mm. Rotate the engine clockwise until the dial indicator stops
moving (it will be necessary to lift up on the valve end of the rocker arm to take any clearance
or play out and to verify that you are on the inner base circle of the camshaft, the lowest point).
Zero the dial indicator at this point. On Tier III Cursor 9 engines rotate the engine
counterclockwise until the dial indicator reads 4.70 +/- 0.05 mm. On Tier IV Cursor 9 engines
rotate clockwise until the dial indicator reads 5.29 mm +- 0.05 mm. Check to see if the "D" hole
is in the window and that the timing pin will lock the flywheel. If the "D" hole is not centered in
the window and the flywheel cannot be locked, loosen the four bolts that retain the camshaft
gear and rotate the flywheel until the "D" hole is in the timing window and the flywheel can be
locked, tighten the four bolts that hold the camshaft gear to the camshaft. Now, verify the
timing by turning the engine clockwise 10° to 20° and then back counterclockwise until the "D"
hole is in the timing window and the timing pin will lock the flywheel. Verify the reading on the
dial indicator is 4.70 +/- 0.05 mm (Tier III), on Tier IV 5.29 mm +- 0.05 mm. Repeat the above
procedure if necessary to obtain the specified timing. Once timing is within the specified range
tighten the camshaft gear retaining bolt to specified torque.
CURSOR 9 TIMING
6. While the flywheel is still locked in the "D" position time the phonic wheel.
Using the phonic wheel timing fork with the flywheel locked in the "D" position, install the
phonic wheel so the timing fork engages the phonic wheel tooth with the "^" mark. Tighten the
phonic wheel retaining bolts to the specified torque.
