Page 3 FOREWORD This workshop manual has been compiled for use in conjunction with normal workshop practice. Mention of certain accepted practices therefore, has been purposely omitted in order to avoid repetition. Reference to renewing joints and cleaning off joint faces has to a great extent been omitted from the text, it being understood that this will be carried out where applicable. Similarly, it is understood that in reassembly and inspection, all parts are to be thoroughly cleaned and where present, burrs and scale are to be removed. It follows that any open ports of high precision components, e.g., fuel injection equipment, exposed by dismantling, will be blanked off until reassembled, to prevent the ingress of foreign matter. : When setscrews or studs are fitted into holes which are tapped through into the inside of : the engine, a suitable sealant must be used on the threads. Throughout this manual, whenever the “left ” or “right ” hand side of the engine is referred to, it is that side of the engine as viewed from the flywheel end. The engine number is stamped on the fuel pump mounting flange as shown in the above illustration. Three systems of engine numbering have been used. On very early engines the serial number consisted of seven digits as follows : – Engine Type Typical Engine Number 4.108 7300269 4.107 7100399 4.99 7000251 Identification on these engines can be identified by cbserving the first two figures of the engine number which remain constant depending on engine type. With later engines, the number consisted of figures and letters Engine Type Typical Engine Number 4.108 108U251 4.107 107U251 4.99 99U251 The first figures represent the capacity of the engine in cubic inches, the letter “U ” signifies that the engine was built in the United Kingdom and the last group of figures comprises the engine serial number. On current engines, the number can consist of up to fifteen letters and figures, a typical number being ED21512U510256D Page4 Safety precautions THESE SAFETY PRECAUTIONS ARE IMPORTANT. Reference must also be made to the local regulations in the country of operation. Do not use these engines in marine applications. Do not change the specification of the engine. Do not smoke when you put fuel in the tank. Clean away any fuel which has fallen and move material which has fuel contamination to a safe place. Do not put fuel in the tank during engine operation (unless really necessary). Never clean, lubricate or adjust the engine during operation (unless you have had the correct training when extreme caution must be used to prevent injury). Do not make any adjustments you do not understand.
