GENERAL
INTRODUCTION
This
manual contains the equipment operating procedures as well as additioual information needed
to
help
the operator
keep
the marine
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 equipment performance and longer equipment life.
Proper
diagnosis
of
a problem
is
the
most
important
step
to
satisfactoIy repair;
consequently,
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 cooling
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
fuctor
is the
use
of
the same brand
of
high detergent diesel lubricating
oil
designed specifically 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
lift
pump
assembly,
fuel
injection
pump,
and in the injectors.
The
diesel
engine
does
differ from the
gasoline
engine,
however,
in its
method
of
handling and firing
of
fuel.
. The carouretor and ignition
SYStems
are
done
away
with and in their place are
two
components - the
fuel
injection pump and fuel
injectors.
ORDERING
PARTS
When
contacting your Westerbke
dealer,
parts
distributor, or the
factory
concerning your Westerbeke unit,
always
provide
the
engine's
model
and
serial
number,
and transsmission
number
as
they
appear on the
black
and silver
"Westerbeke"
plate
which
is
mounted
on
the engine's exhaust
manifold.
Note
that
component
locations in
the
manual
are
referenced.from the front of the engine which is the
pulley/drive belt
end.
(The
flywheel/generator
end
is
the rear end.) Left and right
sides
are detennined
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 at
your
right
Westerbeke
engines are thoroughly
checked
and given a final run under various
load
conditions before
leaving the
factory.
This is done
to
ensure
dependable
operation, long
service,
and a satisfied owner.
Care
at the
factory
during assembly
and
thorough
testing
have
resulted
in
Westerbeke
units being capable
of many thousands
of
hours
of
dependable
service.
However,
the manufacturer cannot control the type of
treatment a unit
receives
in the
field.
This part
is
up
to
the owner/operator.
