INTRODUCTION

Foreword Soil, air, and water are vital factors of agriculture and life in general. When legislation does not yet rule the treatment of some of the substances required by advanced technology, sound judgment should govern the use and disposal of products of a chemical and petrochemical nature.

NOTE: The following are recommendations that may be of assistance: •

Become acquainted with and ensure that you understand the relative legislation applicable to your country.

•

Where no legislation exists, obtain information from suppliers of oils, filters, batteries, fuels, antifreeze, cleaning agents, etc., with regard to their effect on man and nature and how to safely store, use, and dispose of these substances.

•

Agricultural consultants will, in many cases, be able to help you as well.

Helpful hints •

Avoid filling tanks using cans or inappropriate pressurized fuel delivery systems that may cause considerable spillage.

•

In general, avoid skin contact with all fuels, oils, acids, solvents, etc. Most of them contain substances that may be harmful to your health.

•

Modern oils contain additives. Do not burn contaminated fuels and or waste oils in ordinary heating systems.

•

Avoid spillage when draining off used engine coolant mixtures, engine, gearbox and hydraulic oils, brake fluids, etc. Do not mix drained brake fluids or fuels with lubricants. Store them safely until they can be disposed of in a proper way to comply with local legislation and available resources.

•

Modern coolant mixtures, i.e. antifreeze and other additives, should be replaced every two years. They should not be allowed to get into the soil, but should be collected and disposed of properly.

•

Do not open the air-conditioning system yourself. It contains gases that should not be released into the atmosphere. Your CNH dealer or air conditioning specialist has a special extractor for this purpose and will have to recharge the system properly.

•

Repair any leaks or defects in the engine cooling or hydraulic system immediately.

•

Do not increase the pressure in a pressurized circuit as this may lead to a component failure.

•

Protect hoses during welding as penetrating weld splatter may burn a hole or weaken them, allowing the loss of oils, coolant, etc.

Basic instructions - Shop and Assembly SHIMMING For each adjustment operation, select adjusting shims and measure individually using a micrometer, then add up the recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, or the rated value indicated on each shim.

ROTATING SHAFT SEALS For correct rotating shaft seal installation, proceed as follows: •

before assembly, allow the seal to soak in the oil it will be sealing for at least thirty minutes.

•

thoroughly clean the shaft and check that the working surface on the shaft is not damaged.

•

position the sealing lip facing the fluid; with hydrodynamic lips, take into consideration the shaft rotation direction and position the grooves so that they will deviate the fluid towards the inner side of the seal.

•

coat the sealing lip with a thin layer of lubricant (use oil rather than grease) and fill the gap between the sealing lip and the dust lip on double lip seals with grease.

•

insert the seal in its seat and press down using a flat punch or seal installation tool. Do not tap the seal with a hammer or mallet.

•

whilst inserting the seal, check that it is perpendicular to the seat; once settled, make sure that it makes contact with the thrust element, if required.

•

to prevent damaging the seal lip on the shaft, position a protective guard during installation operations.

O-RING SEALS Lubricate the O-RING seals before inserting them in the seats, this will prevent them from overturning and twisting, which would jeopardise sealing efficiency.

SEALING COMPOUNDS Apply one of the following sealing compounds on the mating surfaces when specified: SILMATE® RTV1473, or LOCTITE® RTV 598 or LOCTITE® INSTANT GASKET 587 BLUE. Before applying the sealing compound, prepare the surfaces as directed on product container or as follows: •

remove any incrustations using a metal brush.

•

thoroughly de-grease the surfaces using a locally approved cleaning agent such as safety solvent or brake parts cleaner.

SPARE PARTS Only use "CNH Original Parts" or " CNH Parts".

Only genuine spare parts guarantee the same quality, duration and safety as original parts, as they are the same parts that are assembled during standard production. Only "CNH Original Parts" or " CNH Parts" can offer this guarantee.

When ordering spare parts, always provide the following information: •

machine model (commercial name) and serial number

•

part number of the ordered part, which can be found in the "Microfiches" or the "Service Parts Catalogue", used for order processing

INTRODUCTION

PROTECTING THE ELECTRONIC/ ELECTRICAL SYSTEMS DURING CHARGING OR WELDING To avoid damage to the electronic/electrical systems, always observe the following: 1.

Never make or break any of the charging circuit connections, including the battery connections, when the engine is running.

2.

Never short any of the charging components to ground.

3.

Always disconnect the ground cable from the battery before arc welding on the combine or on any header attached to the combine.

4.

•

position the welder ground clamp as close to the welding area as possible

•

if welding in close proximity to a computer module, then the module should be removed from the combine

•

never allow welding cables to lay on, near or across any electrical wiring or electronic component while welding is in progress

Always disconnect the negative cable from the battery when charging the battery in the combine with a battery charger.

NOTICE: If welding must be performed on the unit, either the combine or the header (if it is attached), the battery ground cable must be disconnected from the combine battery. The electronic monitoring system and charging system will be damaged if this is not done.

Remove the battery ground cable. Reconnect the cable when welding is completed.

WARNING Battery acid causes severe burns. Batteries contain sulfuric acid. Avoid contact with skin, eyes or clothing.

Antidote - EXTERNAL: flush with water. INTERNAL: drink large quantities of water or milk. Follow with milk of magnesia, beaten egg or vegetables oil. Call physician immediately. EYES: flush with water for 15 minutes and get prompt medical attention.

Fuel injection system - Overview

FUELSYSTEM

1

The common rail fuel system is equipped with a special pump that maintains fuel at a constant high pressure regardless of phase and cylinder under injection. The high pressure fuel is accumulated in a common duct shared by all electric injectors. Therefore, fuel at injection pressure, calculated by the EDC, is always available at the electric injection inlet. When the solenoid valve of an injector is energized by the ECU, high pressure fuel is taken directly from the rail and injected into the related cylinder.

Pumping element (3) is oriented to pump shaft (4) cam. During intake, the pumping element is supplied through supply duct (5). The fuel amount to be sent to the pumping element is set by the pressure regulator (7). The pressure regulator meters fuel flow to pumping element according to the Pulse Width Modulated (PWM) signal received from the EDC. During the pumping element compression stage, fuel reaches the pressure required to open the delivery valve to the common rail (2) and to feed it through the outlet (1).

Engine - Fuel injection system

Operation The cylinder is filled through the cap intake valve only if the supply pressure is suitable to open the delivery valves set on the pumping elements. About 2 bar (29 psi).

The amount of fuel supplying the high-pressure pump is metered by the pressure regulator, placed on the low-pressure system. The pressure regulator is controlled by the EDC7 control unit through a PWM signal.

When fuel is sent to a pumping element, the related piston is moving downwards (suction stroke). When the piston stroke is reversed, the intake valve closes and the remaining fuel in the pumping element chamber is compressed above the supply pressure valve existing in the rail.

The generated pressure makes the exhaust valve open and the compressed fuel reached the high-pressure circuit.

The pumping element compresses the fuel till top dead center (delivery stroke) is reached. Afterwards, the pressure decreases till the exhaust valve is closed. The pumping element piston goes back towards the bottom dead center and the remaining fuel is decompressed.

When the pumping element chamber pressure becomes less than supply pressure, the intake valve is again opened and the cycle is repeated.

The delivery valves must always be free in their movements, and free of impurities and oxidation. The rail delivery pressure is modulated by the electronic control unit, through the pressure regulator solenoid valve.

The pump is lubricated and cooled by the fuel.

The radialjet pump disconnection - re-connection time on the engine is highly reduced in comparison with traditional injection pumps, because it does not require setting.

If the pipe between the fuel filter and the high-pressure pump is to be removed and installed, be sure that hands and components are absolutely clean.

Engine - Fuel injection system

Pressure regulating valve - Overview Located at the high-pressure pump inlet, on low pressure system, it modulates the amount of fuel for high-pressure pump supply based on commands received from ECU. It mainly consists of parts below: •

Trapezoidal-section lock pin

•

Valve control pin

•

Pre-load valve

•

Coils

When no control signal is present, the pressure regulator is normally open, therefore the high-pressure pump is in maximum delivery condition.

The ECU modulates a PWM control signal to extend or reduce section of fuel supply line to high-pressure pump.

The component cannot be replaced as an individual part, therefore it cannot be removed.

The quantity high-pressure supply fuel is metered by a proportional valve positioned on the low-pressure system and it is managed by the EDC 7 control unit.

The delivery pressure to the rail is modulated between 250 - 1400 bar (3625 - 20300 psi) by the ECU operating on pressure regulator solenoid valve.

It is a Normally open solenoid valve.

It's resistance is 3.2 Ω.

It is connected to ECU pins C5 and C7.

(3) Pipelines to injectors (4) Fuel supply

(5) Pressure sensor (6) Overpressure valve

The common rail has an internal volume sized to quickly pressurize the fuel at start up, while having a sufficient volume to support full load fuelling rates. The volume in the common rail is sufficient to allow the injectors to supply fuel to the cylinders under full load, while still maintaining a stabile rail pressure, from fuel supplied by the high pressure pump.

A fuel pressure sensor (5) is screwed into the one end of the common rail. It provides feedback to the engine electronic control unit where the sensor values are monitored. Rail pressure is changed as needed based on sensor feedback and other engine operating parameters.

An overpressure valve (6) is installed in the other end. It protects the common rail and associated components by exhausting excess pressure in the rail to the return line and back to the fuel tank. It opens at about 1850 - 1950 bar (26825 - 28275 psi).

Engine - Intake and exhaust manifolds and muffler

Intake and exhaust manifolds and muffler - Overview The cylinder head is of a cross flow design, which means the intake is on one side of the cylinder head and the exhaust is on the other. This provides for a more efficient intake system. With the hot exhaust gases exiting on the opposite side, the intake gases remain cooler and more dense. The turbo-charging system consists of an air filter, and an HX55 turbocharger with waste-gate.

Engine - Engine cooling system

Engine cooling system - Overview The engine cooling system is a closed circuit, forced circulation system. It consists mainly of the following components.

•

Expansion tank (not supplied)

•

A heat exchanger to cool down lubrication oil

•

A water pump with centrifugal system incorporated in the cylinder block

•

Fan (not supplied)

•

A 2-way thermostat controlling the coolant circulation.

The water pump is driven by the crankshaft by a poli-V belt and sends coolant to the cylinder, especially to the cylinder head, (bugger quantity). When the coolant temperature reaches and overcomes the operating temperature, the thermostat is opened and form here the coolant flows into the radiator and is cooled down by the fan. The pressure inside the system, due to the temperature change, is adequately controlled through the expansion vessel.

Electrical systems - Engine control system

EDC system functions The EDC 7 UC31 electronic control unit manages the following main functions: •

Fuel injection

•

Accessory functions such as: •

Cruise control

•

Speed limiter

•

PTO

•

etc,

•

Self diagnosis

•

Recovery

•

Enables interfacing with other electronic systems available on the vehicle for diagnostic purposes

Fuel dosing Fuel dosing is calculated based on •

Accelerator position

•

Engine RPM

•

Quantity of air intake

Fuel delivery corrections based on: •

Coolant temperature •

When the engine is cold, it encounters greater operating resistance, mechanical friction is high and the engine oil is still very viscous. Fuel injected also tends to condense on cold metal surfaces. Fuel dosing is therefore greater than with a hot engine.

Fuel delivery corrections to prevent: •

Noise

•

Fumes

•

Overloads •

•

Behaviors that could lead to the above mentioned items are well known, so the control unit is programmed with specific instructions to prevent them.

Overheating •

In the event of engine overheating, the control unit will "De-rate" the engine. This decreases the fuel delivery proportional to the temperature reached by the coolant.

Pressure can be adjusted in case of •

•

External device actuation •

Speed reducer

•

Cruise control

•

etc.

Serious defects involving load reduction or engine stop

After determining the mass of air introduced by measuring its volume and temperature, the control unit calculates the corresponding mass of fuel to be injected into the cylinder involved. Fuel temperature is also taken into account.

Injection lead Injection lead, or the start of fuel delivery expressed in degrees, can differ from one injection to the next, even from one cylinder to another. It is calculated according to engine load, for example, accelerator position, engine RPM and air intake.

47441641 09/10/2012

55.015 / 9

Electrical systems - Engine control system

Lead is corrected as required: •

During acceleration

•

According to coolant temperature

Lead is used to obtain: •

Reduced emissions

•

Noise abatement

•

No overload

•

Better vehicle acceleration

High injection lead is set at start, based on coolant temperature. Delivery start feedback is given by the electro valve impedance variation.

Engine start Cylinder 1 flywheel and camshaft sensors synchronization takes place at first engine turns. The accelerator pedal signal is ignored at start. Start delivery is exclusively based on coolant temperature. The control unit enables the accelerator pedal, when it detects flywheel acceleration and an increase in RPM.

Cold start Pre-heating is activated when one of the three temperature sensors (coolant, air or fuel), records a temperature below 10 °C (50 °F). The pre-heat warning light goes on when the ignition key is turned to the "ON" position and stays on for a variable period of time according to temperature, while the grid heater raises the temperature of the air, then the light starts blinking to indicate that the engine can be started. The warning light switches off after the engine is running, while the heater continues being fed for a variable period of time to complete the heating process. The operation is cancelled to avoid draining the batteries if the engine is not started within 20-25 seconds with the warning light blinking. The pre-heat curve is also variable based on battery voltage.

Hot start When the ignition key is turned to the "ON" position, the warning light goes on for about 2 seconds for a short test and then switches off when all reference temperatures are above 10 °C (50 °F). The engine can be started at this point.

Run up When the ignition key is turned to the "ON" position, the control unit transfer data stored at a previous engine stop to the main memory (After Run), and diagnoses that data.

After run At each engine stop, the control unit is still fed by the main relay for a few seconds. This enables the microprocessor to transfer data from the main volatile memory to a nonvolatile, cancelable and re-writable (EEPROM) memory to make the data available for the next start (Run Up).

This data essentially consists of: •

Miscellaneous settings

•

Engine idling

•

Component settings

•

Breakdown memory

The process lasts typically from 2 to 7 seconds depending on the amount of data to be stored. the control unit then sends a command to the main relay and makes it disconnect from the battery.

NOTICE: This procedure must never be interrupted. You must wait at least 10 seconds after engine shutdown to disconnect the battery. System operation will not be affected until the fifth improper procedure, after which an error is stored in the breakdown memory and the engine is de-rated to a lower performance at the next start. The EDC warning light will be illuminated. Repeated procedure interruptions could damage the control unit.

Electrical systems - Engine control system

Cut-off Refers to the supply cut-off function during deceleration.

Cylinder balancing individual cylinder balancing contributes to increasing comfort and operability. This function enables individual personalized fuel delivery control and delivery start for each cylinder, to compensate for injector hydraulic tolerances.

The flow differences between the various injectors cannot be evaluated directly by the control unit. This information is provided by the entry of the codes for each injector, by means of the electronic service tool.

Synchronization search The control unit can recognize the to inject fuel into even in the absence of a signal from the camshaft sensor. If this occurs with the engine running, the combustion sequence is already acquired, so the control unit continues with the sequence it has already synchronized on. If it occurs with engine stopped, the control unit actuates one electro valve.

Injection will occur within two shaft revolutions at the most so the control unit is only required to synchronize on the firing sequence and start the engine.
