INTRODUCTION
Foreword - How to use and navigate through this manual
This manual has been produced by a new technical information system. This new system is designed to deliver technical information electronically through web delivery (eTIM), DVD, and paper manuals. A coding system called
SAP has been developed to link the technical information to other Product Support functions, e.g., Warranty.
Technical information is written to support the maintenance and service of the functions or systems on a customer's machine. When a customer has a concern on their machine it is usually because a function or system on their machine is not working at all, is not working efficiently, or is not responding correctly to their commands. When you refer to the technical information in this manual to resolve that customer's concern, you will find all the information classified using the SAP coding, according to the functions or systems on that machine. Once you have located the technical information for that function or system, you will then find all the mechanical, electrical or hydraulic devices, components, assemblies, and sub assemblies for that function or system. You will also find all the types of information that have been written for that function or system: the technical data (specifications), the functional data (how it works), the diagnostic data (fault codes and troubleshooting), and the service data (remove, install adjust, etc.).
By integrating SAP coding into technical information, you will be able to search and retrieve just the right piece of technical information you need to resolve that customer's concern on his machine. This is made possible by attaching
3 categories to each piece of technical information during the authoring process.
The first category is the Location, the second category is the Information Type and the third category is the Product:
• LOCATION - the component or function on the machine, that the piece of technical information is going to describe
(e.g., Fuel tank).
• INFORMATION TYPE - the piece of technical information that has been written for a particular component or function on the machine (e.g., Capacity would be a type of Technical Data describing the amount of fuel held by the fuel tank).
• PRODUCT - the model for which the piece of technical information is written.
Every piece of technical information will have those three categories attached to it. You will be able to use any combination of those categories to find the right piece of technical information you need to resolve that customer's concern on their machine.
That information could be:
• the procedure for how to remove the cylinder head
• a table of specifications for a hydraulic pump
• a fault code
• a troubleshooting table
• a special tool

INTRODUCTION
General specification - Biodiesel Fuels
Fatty Acid Methyl Ester Biodiesel (Biodiesel Fuel) consists of a family of fuels derived from vegetable oils treated with methyl esters.
NOTICE:
Biodiesel Fuel blends are approved for your engine only if they comply with
EN14214
Specification Standards or
ASTM D6751
.
NOTICE:
It is imperative that you check which blend is approved for your engine with your New Holland dealer. Be aware that the use of Biodiesel Fuel that does not comply with the Standards mentioned above could lead to severe damage to the engine and fuel system of your machine. The use of fuels that are not approved may void NEW
HOLLAND AGRICULTURE Warranty coverage.
Biodiesel Fuel Usage Conditions
NOTICE:
The Biodiesel Fuel must meet the fuel Specification mentioned above.
Biodiesel Fuel must be purchased from a trusted supplier that understands the product and maintains good fuel quality. Biodiesel Fuel must be pre-blended by the supplier. Mixing Biodiesel Fuels on-site can result incorrect mixture that can lead to problems with both engine and fuel system.
Engine performance is affected by the use of Biodiesel Fuel. There may be up to
12 %
reduction in power or torque depending on the blend used.
NOTICE:
DO NOT modify the engine and/or injection pump settings to recover the reduced performance.
The reduced power must be accepted if using any Biodiesel Fuel blend.
Some modification may be required to allow your engine to run Biodiesel Fuel. Consult you dealer for complete information on these modifications.
Biodiesel Fuel has a higher cloud point than Diesel Fuel.
NOTICE:
The use of high Biodiesel Fuel blends are not recommended in cold weather conditions.
With Biodiesel Fuels, it may be necessary to change the engine oil, engine oil filter and fuel filter elements more frequently than with Diesel Fuels. Biodiesel Fuel can remove rust and particles from the inside of on-site fuel storage tanks that would normally adhere to the sides of the tank. Like particle deposits that commonly occur with Diesel Fuel, these particles can become trapped by the machine fuel filters, causing blockage and shortening filter life. In cold weather, this is more likely to happen. Consult your New Holland dealer for information on cold weather operation and proper maintenance intervals when using any Biodiesel Fuel blend.
When handling Biodiesel Fuel, care must be taken not to allow water into the fuel supply. Biodiesel Fuel will actually attract moisture from the atmosphere.
Fuel tanks must be kept as full as possible to limit the amount of air and water vapors in them. It may be necessary to drain the fuel filter water tap more frequently.
Potential oxidation and stability could be a problem with the fuel stored in the machine.
NOTICE:
Machines must not be stored for more than three months with Biodiesel Fuel blends in the fuel system.
If long storage periods are necessary, the engine must run on Diesel Fuel for 20 hours to flush the Biodiesel Fuel out of the engine fuel system prior to storage.
NOTICE:
Biodiesel Fuel must not be stored in on-site storage tanks for more than three months.
Any spillage of Biodiesel Fuel must be cleaned up immediately before it can cause damage to the environment and the paint finish of the machine.
Before using Biodiesel Fuel blends you should consult with your dealer to receive full information about the approved blend for your machine and any detailed conditions of its usage.
NOTICE:
Be aware that not fulfilling the requirements and conditions of Biodiesel Fuel usage will void your machine’s
New Holland Warranty coverage.

Engine - Electrical test using DATAR equipment
The engine controller uses the cam and crank sensor information to control the fuelling and injection timing. At initial engine start, the sensor information is used to inform the controller when to initiate first injection. The sensor information is also used by the controller to measure the actual engine speed. The crankshaft and camshaft sensors are both inductive sensors which detect the rotation of the tone wheel. The signal produced must be a clean sine-wave signal without any noise, disturbance or interferences.
• Channel A (Blue)
• Channel B (Red)
Crankshaft, produces a sine-wave signal ranging ±
20 V
. The amplitude
(voltage) will change depending on the engine speed.
Camshaft, produces a sine-wave signal.
