GENERAL
Introduction
This manual contains the equipment operating procedures as well as additional information needed to help
the operator keep the equipment in proper working order. Study and follow the instructions carefully. A
planned maintenance program is included in this manual; adhering
to
the program will result in better equip-
ment 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
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
When contacting your Westerbeke
dealer, parts distributor, or the factory concerning your Westerbeke unit,
always provide the engine's model and serial number, and transmission number as they appear on the black
and silver "Westerbeke" plate Which is mounted on the engine's exhaust manHold. When ordering parts for
your Westerbeke engine, be sure
to
insist upon Westerbeke factory packaged parts, because "will fit"
or
generic parts are frequently not made to the same specHications 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/transmission 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 is your right.
Westerbeke engines and generator sets
afe thoroughly checked and given a final run under various load
conditions before leaving the factory. Test running the engine 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
capable
of
many thousands of hours of dependable service. However, the manufacturer cannot control the
treatment the unit receives in the
field. That part
is
up
to
the owner/operator.
