This service manual has been compiled for engineers engauged in sales, service, inspection and maintenance. Accordingly, descriptions of the construction and functions of the engine are emphasized in this manual while should already ge common knowledge are ommitted.

One characteristic of a marine diesel engine is that its performance in a vessel is governed by its applicability to the vessel's hull construction and its steering system.

Engine installation, fitting out and propeller selection have a substatial effect on the performance of the engine and the vessel. Moreover, when the engine runds unevenly or when trouble occurs, it is essential to check a wide range of operating conditions -- such as instation on the hull and suitability of the ship's piping and propeller -- and not just the engine itself. To get maximum performance from this engine, you should completely understand its functions, construction and capabilities, as well as proper use and servicing.

Use this manual as a handy reference in daily inspection and maintenance, and as a text for engineering guidance.
