General - Westerbeke BCD 4.4KW Operator's Manual

GENERAL
Introduction
This manual contains the equipment operating procedures as well as additional information needed to help
the operator keep the marine equipment in proper working order. Study and follow the instructions careful-
ly. A planned maintenance program is included in this manual; adhering to the program will result in better
equipment performance and longer equipment life. Proper diagnosis of a problem is the most important step
to satisfactory repair; therefore, a troubleshooting table is included.
Understanding the Diesel Engine-Driven Generator
The diesel engine closely resembles the gasoline engine, since the mechanism is essentially the same. The
cylinders are arranged above a closed crankcase; the crankshaft is of the same general type as that of a
gasoline engine; and the diesel engine has the same type of valves, camshaft, pistons, connecting rods, and
lubricating system.
Therefore, to a great extent, a diesel engine requires the same preventive maintenance as a gasoline engine.
The most important factors are proper ventilation and proper maintenance of the fuel, lubricating and cool-
ing systems. Replacement of fuel and lubricating filter elements at the time periods specified is a must, and
frequent checking for contamination (that is, water, sediment, or algae) in the fuel system is also essential.
Another important factor is the use of the same brand of high detergent diesel lubricating oil designed specifi-
cally for diesel engines. Be careful not to put gasoline in the diesel fuel tank(s). Gasoline does not have the
same lubricating qualities as diesel fuel; consequently, gasoline in the fuel lines will damage components in
the fuel lift pump assembly, fuel injection pump and injectors.
The diesel engine does differ from the gasoline engine, however, in its handling and firing of fuel. The car-
buretor and ignition systems are done away with and in their place are two components - the fuel injection
pump and the fuel injectors.
Ordering Parts
Whenever replacement parts are needed, always provide the generator model number, engine serial num-
ber, and generator serial number as they appear on the scarlet and gold name plate located on the gener-
ator end. You must provide us with this information so we may properly identify your generator set. In
addition, include a complete part description and part number for each part needed (see the separately fur-
nished Parts List). Also, be sure to insist upon Westerbeke factory packaged parts because "will fit" or generiC
parts are frequently not made to the same specifications as original equipment.
Note that component locations in the manual are referenced from the front of the engine which is the pul-
ley/drive belt end. (The flywheel/generator end is the rear end.) Left and right sides are determined by the
engine; imagine straddling the engine and facing in the same direction as the front of the engine: the left side
is at your left, the right side at your right.
Westerbeke generators sets are thoroughly checked and given a final run under various load conditions
before leaving the factory. Test running the generator ensures dependable operation, long service, and a
satisfied owner.
Care at the factory during assembly and thorough testing have resulted in a Westerbeke diesel engine-driven
generator capable of many thousands of hours of dependable service. However, what the manufacturer can-
not control is the treatment the unit receives in the field. That part is up to the owner/operator.
