- 2. SECTION 00 - - GENERAL - - CHAPTER 1 1 87679925A - - 12 - - 2007 GENERAL INSTRUCTIONS IMPORTANT NOTICE All maintenance and repair work described in this manual must be performed exclusively by NEW HOLLAND service technicians, in strict accordance with the instructions given and using any specific tools necessary. Anyone performing the operations described herein without strictly following the instructions is personally responsible for any eventual injury or damage to property. SHIMMING For each adjustment operation, select adjusting shims and measure individually using a micrometer, then add up the recorder values: Do not rely on measuring the entire shimming set, which may be incorrect, or the rated value indicated for each on 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; 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 marked with an X: RTV SILMATE, RHODORSIL CAF 1 or LOCTITE PLASTIC GASKET. Before applying the sealing compound, prepare the surfaces as follows: -- remove any incrustations using a wire brush; -- thoroughly de--grease the surfaces using one of the following cleaning agents: trichlorethylene, petrol or a water and soda solution.
- 3. 2 SECTION 00 - - GENERAL - - CHAPTER 1 87679925A - - 12 - - 2007 BEARINGS When installing bearings it is advised to: -- heat the bearings to 80 ÷ 90 °C before fitting on the shafts; -- allow the bearings to cool before installing them. SPRING PINS When fitting split socket elastic pins, ensure that the pin notch is positioned in the direction of the force required to stress the pin. Spiral spring pins do not require special positioning. SPARE PARTS Use solely genuine parts, which guarantee the same quality, duration and safety as the original parts as they are identical to the ones fitted during production. Only genuine parts can offer this guarantee. When ordering spare parts, always provide the following information: -- tractor model (commercial name) and frame number; -- engine type and number; -- part number of the ordered part, which can be found in the “Microfiches” or the “Spare Parts Catalogue”, used for order processing. NOTES FOR EQUIPMENT The tools that NEW HOLLAND propose and illustrate in this manual are: -- specifically researched and designed for use with NEW HOLLAND vehicles; -- necessary to make reliable repair; -- accurately built and strictly tested to offer efficient and long--lasting working means. By using these tools, repair personnel will benefit from: -- operating in optimal technical conditions; -- obtaining the best results; -- saving time and effort; -- working in safe conditions. IMPORTANT NOTES Wear limit values indicated for certain parts are recommended, but not binding. The terms “front”, “rear”, “right--hand” and “left--hand” (when referred to different parts) are intended as seen from the driving position with the tractor in the normal direction of movement. MOVING THE TRACTOR WITH THE BATTERY REMOVED External power supply cables should only be connected to the respective positive and negative cable terminals, using efficient clamps that guarantee adequate and secure contact. Disconnect all services (lights, windshield wipers, etc.) before starting the vehicle. If the vehicle electrical system requires checking, carry out operations with the power supply connected; once checking is completed, disconnect all services and switch off the power supply before disconnecting the cables.
- 4. SECTION 00 - - GENERAL - - CHAPTER 1 3 87679925A - - 12 - - 2007 SAFETY REGULATIONS WARNING AND DANGER SYMBOL This warning symbol points out important messages concerning your safety. Carefully read the following safety regulations and observe advised precautions in order to avoid potential hazards and safeguard your health and safety. In this manual the symbol is accompanied by the following key- -words: WARNING - - Warnings concerning unsuitable repair operations that may jeopardise the safety of Repair personnel. DANGER - - Specific warnings concerning potential hazards for operator safety or for other persons directly or indirectly involved. TO PREVENT ACCIDENTS Most accidents or injuries that occur in workshops are the result of non--observance of simple and fundamental safety regulations. For this reason, IN MOST CASES THESE ACCIDENTS CAN BE AVOIDED: by foreseeing possible causes and consequently acting with the necessary caution and care. Accidents may occur with all types of vehicle, regardless of how well it was designed and built. A careful and judicious service technician is the best guarantee against accidents. Precise observance of the most basic safety rule is normally sufficient to avoid many serious accidents. DANGER. Never carry out any cleaning, lubrication or maintenance operations when the engine is running. SAFETY REGULATIONS GENERAL -- Carefully follow specified repair and maintenance procedures. -- Do not wear rings, wristwatches, jewellery, unbuttoned or loose articles of clothing such as: ties, torn clothing, scarves, open jackets or shirts with open zips that may remain entangled in moving parts. It is advised to wear approved safety clothing, e.g: non--slip footwear, gloves, safety goggles, helmets, etc. -- Do not carry out repair operations with someone sitting in the driver’s seat, unless the person is a trained technician who is assisting with the operation in question. -- Operate the vehicle and use the implements exclusively from the driver’s seat. -- Do not carry out operations on the vehicle withthe engine running, unless specifically indicated. -- Stop the engine and ensure that all pressure is relieved from hydraulic circuits before removing caps, covers, valves, etc. -- All repair and maintenance operations must be carried out using extreme care and attention. -- Service steps and platforms used in a workshop or in the field should be built in compliance with the safety rules in force. -- Disconnect the batteries and label all controls to indicate that the vehicle is being serviced. Block the machine and all equipment which should be raised. -- Do not check or fill fuel tanks, accumulator batteries, nor use starting liquid when smoking or near naked flames, as these fluids are inflammable. -- Brakes are inoperative if manually released for repair or maintenance purposes. Use blocks or similar devices to secure the machine in these conditions. -- The fuel nozzle should always be in contact with the filling aperture. Maintain this position until filling operations are completed in order to avoid possible sparks caused by the accumulation of static electricity.
- 5. 4 SECTION 00 - - GENERAL - - CHAPTER 1 87679925A - - 12 - - 2007 -- Only use specified towing points for towing the tractor, connect parts carefully. Make sure that all pins and/or locks are secured in position before applying traction. Never remain near the towing bars, cables or chains that are operating under load. -- Transport vehicles that cannot be driven using a trailer or a low--loading platform trolley, if available. -- When loading or unloading the vehicle from the trailer (or other means of transport), select a flat area capable of sustaining the trailer or truck wheels, firmly secure the tractor to the truck or trailer and lock the wheels in the position. -- Electric heaters, battery--chargers and similar equipment must only be powered by auxiliary power supplies with efficient ground insulation to avoid electrical shock hazards. -- Always use suitable hoisting or lifting devices when raising or moving heavy parts. -- Take extra care if bystanders are present. -- Never pour gasoline or diesel oil into open, wide and low containers. -- Never use gasoline, diesel oil or other inflammable liquids as cleaning agents.
