INTRODUCTION
IMPORTANT
THIS MANUAL IS A DETAILED GUIDE TO THE INSTALLATION,
START-UP, OPERATION AND MAINTENANCE OF YOUR WESTERBEKE MARINE
DIESEL ENGINE. THE INFORMATION IT CONTAINS IS VITAL TO THE
ENGINE'S DEPENDABLE, LONG TERM OPERATION. READ I T ! KEEP IT IN A SAFE
PLACE ! KEEP IT HANDY FOR REFERENCE AT ALL TIMES !
FAILURE TO DO SO WILL INVITE SERIOUS RISK, NOT ONLY TO YOUR
INVESTMENT BUT YOUR SAFETY AS WELL.
UNDERSTANDING THE DIESEL ....
The diesel engine closely resembles the gasoline engine inasmuch as the mechanism is essentially the same.
Its cylinders are arranged above its closed crankcase; its crankshaft is of the same general type as that of a
gasoline engine; it has the same sort of valves, camshaft, pistons, connecting rods, lubricating system and
reverse and reduction gear.
Therefore, it follows to a great extent that a diesel engine requires the same preventative maintenance as that
which any intelligent operator would give to a gasoline engine. The most important factors are proper
maintenance of the fuel, lubricating and cooling systems. Replacement of fuel and lubricating filter elements
at the time periods specified is a must, and frequent checking for contamination (i.e. water, sediment,etc.)
in the fuel system is also essential. Another important factor is the use of the same brand of ".high detergent"
diesel lubricating oil designed specifically for diesel engines.
The diesel engine does differ from the gasoline engine, however, in the method of handling and firing its fuel.
The carburetor and ignition systems are done away with and in their place is a single component - the Fuel
Injection Pump - which performs the function of both.
Unremitting care and attention at the factory have resulted in a Westerbeke engine capable of many
thousands of hours of dependable service. What the manufacturer cannot control, however, is the treatment
it receives in service. This part rests with you!
ORDERING PARTS
Whenever replacement parts are needed, always include the complete part description and part number
(see separate Parts List furnished, if not part of this publication). Be sure to include the engine's model
and serial number. Also, be sure to insist upon Westerbeke factory packaged parts, because "will fit"
parts are frequently not made to the same specifications as original equipment`.
GENERATOR SETS
Westerbeke diesels are used for both the propulsion of boats and for generating electrical power. For
generator set applications, all details of this Manual apply, except in regard to certain portions of the"
Installation, Operation and Maintenance sections. Additional information is provided in the section titled
Generator Sets, Section T.
