0 2 I ntroduction This Workshop Manual contains technical specifications, descriptions and instructions for the repair of the Volvo Penta products or product types described in the Table of Contents. Check that you have the correct Workshop Manual for your engine. Before starting work on the engine read the "Safety Pre- cautions", "Genera! Information" and "Repair Instruc- tion" sections of this Workshop Manual carefully. I mportant I n this book and on the product you will find the follow- i ng special warning symbols. Q WARNING! Possible danger of personal injury, extensive damage to property or serious mechanical malfunction if the instructions are not followed. I MPORTANT! Used to draw your attention to something that can cause damage or malfunc- tions on a product or damage to property. Note! Used to draw your attention to important information that will facilitate the work or operation in progress. Below is a summary of the risks involved and safety precautions you should always observe or carry out when operating or servicing the engine. I mmobilize the engine by turning off the power supply to the engine at the main switch (switches) and lock it (them) in the OFF position before starting work. Set up a warning notice at the engine control point or helm. As a general rule all service operations must be carried out with the engine stopped. However, some work, for example certain adjustments require that the engine is running when they are carried out. Approaching an engine which is operating is a safety risk. Loose clothing or long hair can fasten in rotating parts and cause serious personal injury. If working in proximity of an engine which is operating, careless movements or a dropped tool can result in personal injury. Take care to avoid contact with hot surfaces (exhaust pipes, Turbocharger ( TC ), air intake pipe, start element etc .) and hot liquids in lines and hoses on an engine which is running or which has just been stopped. Reinstall all protective parts removed during service operations before starting the engine. Safety Precautions 0 0 Check that the warning or information labels on the product are always clearly visible. Replace l abels which have been damaged or painted over. Engines with turbocharger ( TC ): Never start the engine without installing the air cleaner ( ACL ) filter. The rotating compressor in the Turbo can cause serious personal injury. Foreign objects entering the intake ducts can also cause mechanical damage. Never use start spray products or similar when starting the engine. They may cause an explosion in the inlet manifold. Danger of personal injury. Avoid opening the filler cap for engine coolant system (freshwater cooled engines) when the engine is still hot. Steam or hot coolant can spray out. Open the filler cap slowly and release the pressure in the system. Take great care if a cock, plug or engine coolant line must be removed from a hot engine. Steam or hot coolant can spray out in any direction. Hot oil can cause burns. Avoid getting hot oil on the skin. Ensure that the lubrication system is not under pressure before carrying out any work. Never start or operate the engine with the oil filler cap removed, otherwise oil could be ejected. Stop the engine and close the sea cock before carrying out operations on the engine cooling system. Only start the engine in a well-ventilated area. If operating the engine in an enclosed area ensure that there is exhaust ventilation leading out of the engine compartment or workshop area to remove exhaust gases and crankcase ventilation emissions.

0 IL 0 Always use protective glasses or goggles when carrying out work where there is a risk of splin- ters, grinding sparks, acid splashes or where other chemicals are used. The eyes are extremely sensitive, an injury could result in blind- ness! Avoid getting oil on the skin! Repeated exposure to oil or exposure over a long period can result in the skin becoming dry. Irritation, dry- ness and eczema and other skin problems can then occur. Used oil is more dangerous than fresh oil from a health aspect. Use protective gloves and avoid oil soaked clothes and shop rags. Wash regularly, especially before eating. There are special skin creams which counteract drying out of the skin and make it easier to clean off dirt after work is completed. Many chemicals used on the product (for example engine and transmission oils, glycol, gasoline and diesel oil), or chemicals used in the workshop (for example degreasing agents, paint and solvents) are dangerous to health. Read the instructions on the product packaging carefully! Always follow the safety precautions for the product (for example use of protective mask, glasses, gloves etc .). Make sure that other personnel are not exposed to hazardous chemicals, for example in the air. Ensure good ventilation in the work place. Follow the instructions provided when disposing of used or leftover chemicals. Excercise extreme care when leak detecting on the fuel system and testing the fuel injector jets. Use eye protection. The jet from a fuel injector nozzle is under extremely high pressure and has great penetrative energy, so the fuel can penetrate deep into the body tissue and cause serious personal injury. Danger of blood poison- i ng. All fuels and many chemical substances are flammable. Do not allow naked flame or sparks i n the vicinity. Fuel, certain thinner products and hydrogen from batteries can be extremely flammable and explosive when mixed with air. Smoking is not to be permitted in the vicinity! Ensure that the work area is well ventilated and take the necessary safety precautions before starting welding or grinding work. Always ensure that there are fire extinguishers at hand when work is being carried out. O 2L 0 Ensure that rags soaked in oil or fuel and used fuel or oil filters are stored safely. Rags soaked i n oil can spontaneously ignite under certain circumstances. Used fuel and oil filters are envi- ronmentally dangerous waste and must be de- posited at an approved site for destruction together with used lubricating oil, contaminated fuel, paint remnants, solvent, degreasing agents and waste from washing parts. Never expose a battery to naked flame or electrical sparks. Never smoke in proximity to the batteries. The batteries give off hydrogen gas during charging which when mixed with air can form an explosive gas - oxyhydrogen . This gas i s easily ignited and highly volatile. Incorrect connection of the battery can cause a single spark which is sufficient to cause an explosion with resulting damage. Do not shift the connec- tions when attempting to start the engine (spark risk) and do not lean over any of the batteries. Always ensure that the Plus (positive) and Mi- nus (negative) battery leads are correctly installed on the corresponding terminal posts on the batteries. Incorrect installation can result in serious damage to the electrical equipment. Re- fer to the wiring diagrams. Always use protective goggles when charging and handling the batteries. Battery electrolyte contains sulfuric acid which is highly corrosive. Should the battery electrolyte come into contact with unprotected skin wash off immediately us- i ng plenty of water and soap. If battery acid comes in contact with the eyes, immediately flush with plenty of water and obtain medical as- sistance at once. A Turn the engine off and turn off the power at the main switch(es) before carrying out work on the electrical system. Clutch adjustments must be carried out with the engine stopped. 3

About this Workshop Manual This Workshop Manual contains technical specifications, descriptions and instructions for the repair of the following engines in standard format: MD2010 , MD2020 , MD2030 , MD2040 . This Workshop Manual can show operations carried out on any of the engines li sted above. As a result the illustrations and pictures in the manual that show certain parts on the engines, do not in some cases apply to all the engines listed. How- ever the repair and service operations described are in all essential details the same. Where they are not the same this is stated in the manual and where the differ- ence is considerable the operations are described sep- arately. The Engine Designations and Engine Number can be found on the product plate. Please always in- clude both the engine designation and the engine number in all correspondance . The Workshop Manual is produced primarily for the use of Volvo Penta workshops and service technicians. For this reason the manual presupposes a certain basic knowledge of marine propulsion systems and that the user can carry out the mechanical/electrical work described to a general standard of engineering compet- ence. Volvo Penta products are under a continual process of development and we therefore reserve all rights regard- i ng changes and modifications. All the information in this manual is based on product specifications available at the time the book was published. Any essential changes or modifications introduced into production or updated or revised service methods introduced after the date of publication will be provided in the form of Ser- vice Bulletins. Replacement parts Replacement parts for the electrical and fuel systems are subject to various national safety requirements, for example the United States Coast Guard Safety Regula- tions. Volvo Penta Original Spare Parts meet these specifications. Any type of damage which is the result of using replacement parts that are not original Volvo Pen- ta replacement parts for the product in question will not be covered under any warranty or guarantee provided by AB Volvo Penta. Certified engines For engines certified for national and regional environmental legislation the manufacturer undertakes to ensure compliance with such environmental requirements for both new engines and engines is use. The product must comply with the approved example on certifica- tion. For Volvo Penta as the manufacturer to be able ac- cept responsibility for the compliance of engines in use with the set environmental requirements, the following requirements for service and spare parts must be ful- filled: General Information • The service intervals and maintenance proced- ures recommended by Volvo Penta must be fol- l owed. • Only Volvo Penta Genuine Spare Parts intended for the certified engine version must be used. • Service of injection pumps, pump settings, and i njectors, shall always be conducted by an aut- horised Volvo Penta workshop. • The engine must not be rebuilt or modified in any way, with the exception of the accessories and service kits that Volvo Penta has developed for the engine. • I nstallation adjustments on exhaust pipes and supply air channels for the engine compartment (ventilation channels) must not, without due care, be conducted since this can influence exhaust emissions. • Seals must not be broken by unauthorised personnel. Q I MPORTANT! Use only Volvo Penta Genuine Spare Parts. The use of non genuine parts i mplies that AB Volvo Penta will no longer assume responsibility for compliance of the engine with the certified versions. All types of damage or costs resulting from the use of non genuine Volvo Penta spare parts for the product in question will not be regulated by Volvo Penta. 5

The working methods described in the Workshop Man- ual apply to work carried out in a workshop. The engine has been removed from the boat and is installed in an engine fixture. Unless otherwise stated reconditioning work which can be carried out with the engine in place follows the same working method. Warning symbols used in this Workshop Manual (for full explanation of the symbols refer to the section; "Safety Precautions") A AL Note! are not in any way comprehensive since it is impossible to predict every circumstance under which service work or repairs may be carried out. Volvo Penta AB can only i ndicate the risks considered likely to occur as a result of incorrect working methods in a well-equipped workshop using working methods and tools tested by Volvo Penta AB. All operations described in the Workshop Manual for which there are Volvo Penta Special Tools available assume that these tools are used by the service technician or person carrying out the repair. Volvo Penta Spe- cial Tools have been specifically developed to ensure as safe and rational working methods as possible. It is therefore the responsibility of the person or persons us- i ng other than Volvo Penta Special Tools or approved Volvo Penta working methods (as described in a Work- shop Manual or Service Bulletin), to acquaint them- selves of the risk of personal injury or actual mechan- i cal damage or malfunction that can result from failing to use the prescribed tools or working method. I n some cases special safety precautions and user instructions may be required in order to use the tools and chemicals mentioned in the Workshop Manual. Always follow these precautions as there are no specific instructions given in the Workshop Manual. By following these basic recommendations and using common sense it is possible to avoid most of the risks i nvolved in the work. A clean work place and a clean engine will eliminate many risks of personal injury and engine malfunction. Above all when working on the fuel system, engine lubrication system, air intake system, Turbocharger unit, bearing seals and seals it is extremely important to observe the highest standards of cleanliness and avoid dirt or foreign objects entering the parts or systems, since this can result in reduced service life or malfunc- tions. 6 WARNING! I MPORTANT! Repair instructions and methods Our joint responsibility Every engine consists of many systems and components that work together. If one component deviates from the technical specifications this can have dramatic con- sequences on the environmental impact of the engine even if it is otherwise in good running order. It is therefore critical that the stated wear tolerances are ob- served, that systems which can be adjusted are correctly set up and that only Volvo Penta Original Parts are used on the engine. The stated service intervals in the Maintenance Schedule must be followed. Some systems, such as the components in the fuel system, require special expertise and special testing equipment for service and maintenance. Some components are factory sealed for environmental and product specific reasons. Under no circumstances attempt to service or repair a sealed component unless the service technician carrying out the work is authorized to do so. Bear in mind that most of the chemicals used around boats are harmful to the environment if used incorrectly. Volvo Penta recommends the use of bio-degradable degreasing agents for all cleaning of engine components unless otherwise stated in the Workshop Manual. When working onboard a boat make a special point of preventing oil, waste water from washing components entering the bilges ; i nstead remove all such waste for safe disposal at an approved site for destruction. Tightening torques The correct tightening torques for critical joints which must be tightened using a torque wrench are listed under "Technical Specifications - Tightening Torques " and stated in the method descriptions in the Workshop Manual. All tightening torques apply to cleaned threads, bolt heads and mating surfaces. Tigthening torques stated are for lightly oiled or dry threads. Where grease, l ocking or sealing agents are required for screwed j oints this is stated in both the operation description and i n "Tightening Torques". Where no tightening torque is stated for a joint use the general tightening torques according to the tables below. The tightening torques stated are a guide and the joint does not have to be tightened using a torque wrench. Dimension Tightening torque Nm ft.Ibs M5 6 4 M6 10 7 M8 25 18 M - 1 0 50 37 M12 80 59 M14 140 103

Tightening torque with Protractor tightening (angle tightening) Tightening using both a torque setting and a protractor angle requires that first the recommended torque is applied using a torque wrench and then the recommended angle is added according to the protractor scale. Ex- ample: a 90° protractor tightening means that the joint is tightened a further 1/4 turn in one operation after the stated tightening torque has been applied. Lock nuts Do not re-use lock nuts that have been removed during dissassembly operations as these have reduced service life when re-used - use new nuts when assembling or reinstalling. For lock nuts with a plastic insert such as Nylock® the tightening torque stated in the table is reduced if the Nylock® nut has the same head height as a standard hexagonal nut without plastic insert. Reduce the tightening torque by 25% for bolt size 8 mm or larger. Where Nylock® nuts are higher, or of the same height as a standard hexagonal nut, the tightening torques given in the table apply. Strength classes Bolts and nuts are divided up into different classes of strength; the class is indicated by the number on the bolt head. A high number indicates stronger material, for example a bolt marked 10-9 indicates a higher strength than one marked 8-8. It is therefore important that bolts removed during the disassembly of a bolted j oint must be reinstalled in their original position when assembling the joint. If a bolt must be replaced check in the replacement parts catalogue to make sure the correct bolt is used. Sealant A number of sealants and locking liquids are used on the engines. The agents have varying properties and are used for different types of jointing strengths, operating temperature ranges, resistance to oil and other chemicals and for the different materials and gap sizes i n the engines. To ensure service work is correctly carried out it is important that the correct sealant and locking fluid type is used on the joint where the agents are required. I n this Volvo Penta Workshop Manual the user will find that each section where these agents are applied in production states which type was used on the engine. During service operations use the same agent or an al- ternative from a different manufacturer. Make sure that mating surfaces are dry and free from oil, grease, paint and anti-corrosion agent before apply- i ng sealant or locking fluid. Always follow the manufacturer's instructions for use regarding temperature range, curing time and any other instructions for the product. Two different basic types of agent are used on the engine and these are: RTV agent (Room temperature vulcanizing). Used for gaskets, sealing gasket joints or coating gaskets. RTV i s visible when a part has been disassembled; old RTV must be removed before resealing the joint. The following RTV agents are mentioned in the Service Manual: Loctite® 574, Volvo Penta P/N 840879-1, Per- matex® No. 3, Volvo Penta P/N 1161099-5, Permatex® Nr 77. Old sealant can be removed using methylated spirits in all cases. Anaerobic agents. These agents cure in an absence of air. They are used when two solid parts, for example cast components, are installed face-to-face without a gasket. They are also commonly used to secure plugs, threads in stud bolts, cocks, oil pressure switches and so on. The cured material is glass-like and it is therefore colored to make it visible. Cured anaerobic agents are extremely resistant to solvents and the old agent cannot be removed. When reinstalling the part is carefully de- greased and then new sealant is applied. The following anaerobic agents are mentioned in the Workshop Manual: Loctite® 572 (white), Loctite® 241 (blue). Note: Loctite® is the registered trademark of Loctite Corparation , Permatex® the registered trademark of the Permatex Corporation. 7

Safety rules for fluorocarbon rubber Fluorocarbon rubber is a common material in seal rings for shafts, and in O-rings, for example. When fluorocarbon rubber is subjected to high tem- peratures (above 300°C/572°F), hydrofluoric acid can be formed, which is highly corrosive. Skin contact can give severe chemical burns. Splashes in your eyes can give severe chemical burns. If you breathe in the fumes, your lungs can be permanently damaged. 4 f WARNING! Be very careful when working on engines which have been exposed to high tem- peratures, e.g . overheating during a seizure or fire. Seals must never be cut with an oxyacet- ylene torch, or be burned up afterwards in an uncontrolled manner. • Always use gloves made of chloroprene rubber (gloves for handling chemicals) and protective goggles. • Handle the removed seal in the same way as corrosive acid. All residue, including ash, can be highly corrosive. Never use compressed air to blow anything clean. • Put the remains in a plastic box which is sealed and provided with a warning label. Wash the gloves under running water before removing them. The following seals are probably made from fluorocarbon rubber: Seal rings for the crankshaft, camshaft, intermediate shafts. O-rings irrespective of where they are installed. O-rings for cylinder liner sealing are almost always made from fluorocarbon rubber. Note that seals which have not been subjected to high temperature can be handled normally. 8
