Foreword - Ecology and the environment
When legislation does not yet rule the treatment some the substances required advanced technology , sound judgment should govern the use and disposal products a chemical and petrochemical nature.
air , and water are vital factors agriculture and life
NOTE: The following are recommendations that may assistance:
• Become acquainted with and ensure that you understand the relative legislation applicable your country
• Where legislation exists, obtain information from suppliers oils, filters, batteries, fuels, antifreeze, cleaning with regard their fect man and nature and how safely and dispose these
• Agricultural consultants many able help you
Helpful hints
• A void filling tanks using cans inappropriate pressurized fuel delivery systems that may cause considerable
• avoid skin contact with all
Most them contain substances that may harmful your
• Modern oils contain additives. not burn contaminated fuels and waste oils ordinary heating systems.
• A void spillage when draining f used engine coolant gearbox and hydraulic brake not mix drained brake fluids fuels with lubricants. Store them safely until they can disposed a proper way comply with local legislation and available
• Modern coolant antifreeze and other should replaced every two They should not allowed get into the but should collected and disposed properly
• not open the air - conditioning system contains gases that should not released into the Y our NEW HOLLAND AGRICUL TURE dealer air conditioning specialist has a special extractor for this purpose and will have recharge the system properly
• Repair any leaks defects the engine cooling hydraulic system immediately .
• not increase the pressure a pressurized circuit this may lead a component
• Protect hoses during welding penetrating weld splatter may burn a hole weaken allowing the loss

Foreword - How use and navigate through this manual
This new system designed deliver technical information electronically through web delivery and paper A coding system called SAP has been developed link the technical information other Product Support functions, e.g., W arranty .
This manual has been produced a new technical information
T
echnical information written support the maintenance and service the functions systems a When a customer has a concern their machine usually because a function system their chine not working not working ficiently , not responding correctly their When you refer the technical information this manual resolve that you will find all the information classified using the SAP coding, according the functions systems that machine. Once you have located the technical information for that function you will then find all the electrical hydraulic and sub assemblies for that function Y will also find all the types information that have been written for that function system: the technical data the functional data (how the diagnostic data (fault codes and and the service data install integrating SAP coding into technical you will able search and retrieve just the right piece technical information you need resolve that concern his This made possible attaching 3 categories each piece technical information during the authoring process.
The first category the the second category the Information T ype and the third category the Product:
• LOCA TION - the component function the machine, that the piece technical information going describe Fuel
• INFORMA TION TYPE - the piece technical information that has been written for a particular component tion the machine Capacity would a type T echnical Data describing the amount fuel held the fuel
• PRODUCT - the model for which the piece technical information
written.
Every piece technical information will have those three categories attached Y will able use any nation those categories find the right piece technical information you need resolve that concern their
That information could be:
• the procedure for how remove the cylinder head
• a table specifications for a hydraulic pump
• a fault code
• a troubleshooting table
• a special tool

The pressurised oil fed from the main oil duct the turbocharger and the pressurised air compressor (if the bearings the idler gear , the camshaft bearings and the valve mechanism are lubricated with pressurised oil via the main oil
The piston tops are sprayed with and cooled oil from below long the lube oil pressure greater than 3 bar . The oil pressure valve regulates the lube oil pressure such that held a certain range regardless the engine Depending oil viscosity and the oil pressure between 2.5 - 5 bar engine idling the oil pressure must least 1 bar

Intake and exhaust system
SS05N357
Compared aspirated engines which are turbocharged react more sensitively badly maintained air filters and leaks the intake and exhaust
Therefore the prescribed maintenance and inspection work carried out conscientiously and the maintenance intervals observed.
Condition the air filter and the intake system:
The s performance and the life the engine are also largely dependent the condition the air filter and the intake
T dirty air filter a bent intake hose will reduce the performance and result engine oil being drawn through the shaft mounting gasket the turbocharger
NOTE: A leaky air filter (damaged air damaged missing seal) leaks the intake system between the air filter and the turbocharger allow larger impurities enter the turbocharger and subsequently the cylinders the engine.
The filter system for the intake air consists advance cyclone filter (integrated the air filter) and a dry air filter with safety cartridge. The intake air rotated the advance cyclone filter . Heavy particles dirt are thereby deposited towards the outside and are separated the advance cyclone filter ’ s dust removal
Ejector:
The tractor can equipped with for use extremely dusty injector , whose hose connection sucks continuously when the engine fitted the exhaust The dust particles rating the pre - filter are continuously sucked via a hose connection and discharged into the atmosphere together with the exhaust

Design the filter cartridges:
The dirt particles the air are collected the main cartridge which can cleaned necessary The inner safety cartridge prevents dirt particles penetrating into the engine the event a fault incorrectly installed main For maintenance the filter cartridge please see the operating
Display for filter service:
There a pressure dif ference switch the filter This switch illuminates a monitoring lamp and a symbol the ADIC when the air filter has reached a particular level contamination. The intake system also includes the air pipes between the air filter and the turbocharger , and between the turbocharger and the charge air cooler , well between the charge air cooler and the intake
The exhaust manifold fixed the cylinder head with special screws without a separate gasket. Retightening the special screws not necessary
The turbocharger lubricated and cooled with oil from the engine lubrication
Charge air cooling:
The intake air compressed the turbocharger can reach a temperature 150 for high degrees capacity cooled - a charge air cooler which located front the engine radiator (air / air Cooling the charge air lowers the thermal and mechanical load the engine and reduces the discharge nitrogen oxides and sooty particles.
Boost pressure and charged air temperature parameters for engine control:
A combined sensor located the air collector . continually supplies the electronic engine management (EEM3) with information about the boost pressure and charged air conjunction with the common rail injection fuel injection optimised and the discharge nitrogen oxides and sooty particles significantly
The charge air cooler designed service - friendly . can folded and can thus fectively cleaned against the direction the outside air blowing against The folding charge air cooler also allows easy access the other
