SECTION 00 -- GENERAL GUIDELINES -- CHAPTER 1 1 603.54.511.00 -- 03 -- 2006 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 re- sponsible 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 recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, or the rated value indicated for 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 direc- tion 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 con- tact 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 twist- ing, which would jeopardise sealing efficiency. SEALING COMPOUNDS Apply one of the following sealing compounds on the mating surfaces marked with an X: RTV SILMATE, RHO- DORSIL 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.
2 SECTION 00 -- GENERAL GUIDELINES -- CHAPTER 1 603.54.511.00 -- 03 -- 2006 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 spring 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. TOOLS The tools that NEW HOLLAND offer and illustrate in this manual are: -- specifically researched and designed for use with NEW HOLLAND vehicles; -- essential for reliable repair operations; -- accurately built and rigorously tested so as to offer efficient and long--lasting operation. 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 vehicle 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.

SECTION 00 -- GENERAL GUIDELINES -- CHAPTER 1 1 603.54.511.00 -- 03 -- 2006 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 re- sponsible 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 recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, or the rated value indicated for 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 direc- tion 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 con- tact 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 twist- ing, which would jeopardise sealing efficiency. SEALING COMPOUNDS Apply one of the following sealing compounds on the mating surfaces marked with an X: RTV SILMATE, RHO- DORSIL 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.
  • 14. 2 SECTION 00 -- GENERAL GUIDELINES -- CHAPTER 1 603.54.511.00 -- 03 -- 2006 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 spring 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. TOOLS The tools that NEW HOLLAND offer and illustrate in this manual are: -- specifically researched and designed for use with NEW HOLLAND vehicles; -- essential for reliable repair operations; -- accurately built and rigorously tested so as to offer efficient and long--lasting operation. 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 vehicle 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.
