0 General 1 GENERAL TO THE USER This Workshop Manual is intended to assist with workshop operations and repair work. 4th Generation engines (types 33, 44, 49, 66, 74, 84 and 98) are generally of the same construction, so the same repair instructions will usually apply to various engine types. The differences between the various engine types, which affect repair work, are mentioned in the technical data and repair instructions. All measurements are in millimetres and valid when the temperature of the parts is +20°C, unless otherwise stated. Before starting any repair work, please read the safety instructions at the beginning of this book. Make sure that you have all the necessary tools, parts and accessories to hand. The special tools mentioned in the work instructions are not all essential, but they speed up and facilitate the work and contribute to successful execution of the work. An engine which has undergone repairs must be run in just like a new one. Should the engine require work not described in this manual, please consult your local agent or the Serv- ice Department of AGCO SISU POWER Inc., Linnavuori, Finland. To facilitate consulting, find out the following facts about the engine before contacting us: - engine type - engine number - model or equipment - hours operated or kilometres driven. This Workshop Manual does not cover the regular service procedure as this is explained in the 4th Gen- eration series Instruction Manual. As AGCO SISU POWER Inc. is continuously developing its products, all rights are reserved to alter the specifications, accessories and the service and repair procedure without separate notice.

2 General 0 SAFETY INSTRUCTIONS There is always the risk of injury when using or servicing the engine. Before starting the service, please ensure you have read and understood the following safety instructions and re- marks! Do not start any repair work that you do not fully understand. Make sure that the location and surroundings in which you are carrying out the repair provide a safe environment in which to work. Always ensure the location is clean and free of clutter. Do not use faulty or otherwise unsuitable tools. Remove all rings, chains and watches before starting work. Use up-to-date protection equipment while you work. For example, eye protection, as you will be working with compressed air for cleaning, grinding, hammering or similar. Use a lifting device for lifting and transporting heavy (over 20 kg) pieces. Ensure all lifting hooks and chains are in good condition. The lifting eyes on the engine must not be subjected to side forces during lifting. Never work under an engine that is hanging from a lifting device or raised up on a jack. Always use strong supports before starting the work. Use only genuine AGCO Sisu Power spare parts. Start the engine only by using the starting switch in the cabin. Do not start an engine if the protection covers are removed. Note! The fan is difficult to see when the engine is running! Ensure that loose clothing or long hair does not get caught in the rotating parts of the engine. If you start the engine indoors, ensure that there is proper ventilation. Never use an aerosol starting aid! (Risk of explosion, personal injuries and engine damage.) When you are operating the engine or working near it, use ear protection to avoid noise injuries. Always stop the engine before starting any servicing or repair work. Avoid touching the exhaust manifold, turbocharger and any other hot parts of the engine. Open the radiator cap with care when the engine is hot, as the cooling system is pressurised. The cooling liquid and lubrication oil of a hot engine will cause injury if they come into contact with skin. Do not open high pressure pipe connectors of the fuel system when the engine is running. Wait at least 30 sec. after the stopping of the engine. If the jet of high pressure fuel contacts your skin, fuel penetrates the skin causing severe injuries. Get medical help immediately! Never allow a naked flame, smoking or sparks near the fuel system or batteries, especially when loading batteries, as these are explosive. Always disconnect the negative (-) battery cable when servicing or repairing the electric system.

0 General 3 At temperatures in excess of 300°C, e.g. if the engine is burnt by a fire, the viton seals of the engine (i.e. the undermost cylinder liner O-ring) produce very highly corrosive hydrofluoric acid. Do not touch with bare hands when viton seals are subjected to abnormally high temperatures. Always use neoprene rubber or heavy-duty gloves and safety glasses when decontaminating. Wash the seals and the contaminated area with a 10% calcium hydroxide or other alkali solu- tion. Put all removed material in sealed plastic bags and deliver them to the relevant disposal point provided by the authorities concerned. Note! Never destroy viton seals by burning! When checking fuel injectors do not allow the jet of high-pressure fuel to come into contact with your skin. The fuel penetrates the skin causing severe injuries. Get medical help immediately! The fuel, lubricating oil and coolant cause long-lasting irritation on contact with skin. If you are carrying out welding or similar high current operations for the appliance, we recom- mend that you disconnect the EEM4 control unit main connector before starting work. Avoid unnecessary idling of the engine. Do not let oil and other liquids to the environment when servicing the engine. Take them to a proper disposal point. All the engine gaskets are made of non-asbestos material. Be careful when washing the engine with high-pressure washing machine equipment. Do not use high pressure to wash e.g. the electric and fuel equipment or the radiator because they can easily be damaged.
