INTRODUCTION Note to the Owner General instructions Important notice All maintenance and repair operations described in this manual should be carried out exclusively by the CASE IH authorised workshops. All instructions detailed should be carefully observed and special equipment indicated should be used if necessary. Everyone who carries out service operations described without carefully observing these prescriptions will be directly responsible of deriving damages. Shimming At each adjustment, select adjusting shims, measure them individually using a micrometer and then sum up recorded values. Do not rely on measuring the whole shimming set, which may be incorrect, or on rated value indicated for each shim. Rotating shaft seals To correctly install rotating shaft seals, observe the following instructions: • Let the seal soak into the same oil as it will seal for at least half an hour before mounting. • Thoroughly clean the shaft and ensure that the shaft working surface is not damaged. • Place the sealing lip towards the fluid. In case of a hydrodynamic lip, consider the shaft rotation direction and orient grooves in order that they deviate the fluid towards the inner side of the seal. • Coat the sealing lip with a thin layer of lubricant (oil rather than grease) and fill with grease the gap between the sealing lip and the dust lip of double lip seals. • Insert the seal into its seat and press it down using a flat punch. Do no tap the seal with a hammer or a drift. • Take care to insert the seal perpendicularly to its seat while you are pressing it. Once the seal is settled, ensure that it contacts the thrust element if required. • To prevent damaging the sealing lip against the shaft, place a suitable protection during installation. O-rings Lubricate the O-rings before inserting them into their seats. This will prevent the O-rings from rolling over and twine during mounting which will jeopardise sealing. Sealers Apply one of the following sealers: RTV SILMATE, RHODORSIL CAF 1, or LOCTITE PLASTIC GASKET over the mating surfaces marked with an X. Before applying the sealer, prepare the surface as follows: • Remove possible scales using a metal brush. • Thoroughly degrease the surfaces using one of the following cleaning agent: trichlorethylene, petrol or a water and soda solution. Bearings It is advisable to heat the bearings to 80 - 90 °C (176 - 194 °F) before mounting them on their shafts and cool them down before inserting them into their seats with external tapping. Roll pins When fitting straight roll pins, ensure that the pin notch is oriented in the direction of the effort to stress the pin. Coil roll pins can be installed in any position. 47445484 30/08/2013 3

INTRODUCTION Notes for spare parts Use exclusively genuine CASE IH spare parts. Only genuine parts guarantee same quality, life, safety as original components as they are the same as mounted in production. Only the CASE IH genuine spare parts can offer this guarantee. All spare parts orders should be complete with the following data: • Tractor model (commercial name) and frame number. • Engine type and number. • Part number of the ordered part, which can be found on the “Microﬁches” or the “Spare parts catalogue”, which is the base for order processing. Notes for equipment Equipment which CASE IH proposes and shows in this manual are as follows: • Studied and designed expressly for use on CASE IH tractors. • Necessary to make a reliable repair. • Accurately built and strictly tested to offer efﬁcient and long-lasting working means. We also remind the repair personnel that having these equipment means: • Work in optimal technical conditions. • Obtain best results. • Save time and effort. • Work more safely. Notices Wear limits indicated for some details should be intended as advised, but not binding values. The words “front”, “rear”, “right hand”, and “left hand” referred to the different parts should be intended as seen from the operator’s seat oriented to the normal sense of movement of the tractor. How to move the tractor with the battery removed Cables from the external power supply should be connected exclusively to the respective terminals of the tractor positive and negative cables using pliers in good condition which allow proper and steady contact. Disconnect all services (lights, wind-shield wipers, etc.) before starting the tractor If it is necessary to check the tractor electrical system, check it only with the power supply connected. At check end, disconnect all services and switch the power supply Off before disconnecting the cables. 47445484 30/08/2013 4

INTRODUCTION Safety rules Pay attention to this symbol This warning symbol points out important messages involving personal safety. Carefully read the safety rules contained herein and follow advised precautions to avoid potential hazards and safeguard your safety and personal integrity. In this manual you will find this symbol together with the following key- words: WARNING – It gives warning about improper repair operations and deriving potential consequences af- fecting the service technician’s personal safety. DANGER – It gives specific warning about potential dangers for personal safety of the operator or other persons directly or indirectly involved. To prevent accidents Most accidents and personal injuries taking place in workshops are due from non-observance of some simple and essential prudential rule and safety precautions. For this reason, IN MOST CASES THEY CAN BE AVOIDED. It suffices to foresee possible causes and act consequently with necessary caution and care. The possibility that an accident might occur with any type of machines should not be disregarded, no matter how well the machine in question was designed and built. A wise and careful service technician is the best precautions against accidents. Careful observance of this only basic precaution would be enough to avoid many severe accidents. DANGER: Never carry out any cleaning, lubrication or maintenance operations when the engine is running. Safety rules Generalities • Carefully follow specified repair and maintenance procedures. • Do not wear rings, wristwatches, jewels, unbuttoned or flapping clothing such as ties, torn clothes, scarves, open jackets or shirts with open zips which could get hold into moving parts. We advise to use approved safety clothing such as anti-slipping footwear, gloves, safety goggles, helmets, etc. • Never carry out any repair on the machine if someone is sitting on the operator’s seat, except if they are certified operators to assist in the operation to be carried out. • Never operate the machine or use attachments from a place other than sitting at the operator’s seat. • Never carry out any operation on the machine when the engine is running, except when 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 should be carried out with the greatest care and attention. • Service stairs 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 warn that the tractor is being serviced. Block the machine and all equipment which should be raised. • Never check or fill fuel tanks and accumulator batteries, nor use starting liquid if you are smoking or near open flames as such fluids are flammable. • Brakes are inoperative when they are manually released for maintenance purposes. In such cases, the machine should be kept constantly under control using blocks or similar devices. • The fuel filling gun should remain always in contact with the filler neck. Maintain this contact until the fuel stops flowing into the tank to avoid possible sparks due to static electricity buildup. • Use exclusively specified towing points for towing the tractor. Connect parts carefully. Ensure that foreseen pins and/or locks are steadily fixed before applying traction. Do not stop near towing bars, cables or chains working under load. 47445484 30/08/2013 5
