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
Gasoline
Engine-Driven
Generator
The gasoline engine driving an AC generator is in many ways similar
to
a gasoline automobile engine. The
cylinders are vertical in-line, and the engine's cylinder head has an overhead camshaft which is belt-driven.
The engine utilizes conventional points and a condenser-type distributor which is horizontally mounted and
camshaft-driven. The engine incorporates a pressure-type lubrication system, and a fresh water-cooled
en-
gine block which is thermostatically-controlled. To a large degree, the generator's engine requires the same
preventive maintenance that is required of a gasoline automobile engine. The most important factors
to
the
generator's longevity are proper ventilation, maintenance
of
the fuel system, ignition system, cooling sys-
tem, lubrication system and the AC alternator.
Ordering
Parts
Whenever replacement parts are needed, always provide the generator model number designation
(I.e.
4.5
f<YV
BCG), engine serial number, and generator serial number
as
they appear on the data plates located on
the generator end and on the exhaust manifold.
You
I1lIJ.S1
provide us with this information
sowe
may proper-
ly identify your generator set. In addition, include a complete part description and part number for each part
needed (see the separately furnished Parts List). Also, be sure
to
insist upon Westerbeke factory packaged
parts, because
'will fit"
or
generic parts are frequently
nol
made
to
the same specifications
as
original equip-
ment.
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 gasoline engine-
driven generator capable of many thousands of hours of dependable service. However, what the manufac-
turer cannot always control is the manner
or
location the generator is installed in the vessel
or
the manner
in which the unit is operated and serviced in the field. That part is up
to
the buyer/owner-operator.
