INTRODUCTION
COMPONENT
LOCATIONS
Component
locations
in
this
manual
are
referenced
from
the
front
of
the
engine
which
is
the
end
at
which
the
raw
water
pump
is
located.
Left
and
right
sides
are
detennined
as
follows:
imagine
straddling
the
engine,
facing
the
front
of
the
engine:
the
left
side
is
at
your
left,
the
right
side
is
at
your
right.
UNDERSTANDING
THE
DIESEL
ENGINE
The
diesel
engine
closely
resembles
the
gasoline
engine,
since
the
mechanism
is
essentially
the
same.
The
cylinder
is
arranged
above
a
closed
crankcase.
The
crankshaft
is
of
the
same
general
type
as
on
a
gasoline
engine,
and
the
diesel
engine
has
the
same
types
of
valves,
camshaft,
piston,
connecting
rod
and
lubricating
system.
Therefore,
to
a
great
extent,
a
diesel
engine
requires
the
same
pre-
ventive
maintenance
as
a
gasoline
engine.
The
most
important
factors
are
proper
ventilation
and
proper
maintenance
of
the
fuel,
lubricating
and
cooling
systems.
Fuel
filter
elements
must
be
replaced
at
the
time
periods
specified.
and
frequent
checking
for
contaminants
(water,
sediment,
etc.)
in
the
fuel
system
is
also
essential.
Another
important
factor
is
the
consistent
use
of
the
same
brand
of
high
detergent
diesel
lubrication
oil
designed
specifically
for
diesel
engines.
The
diesel
engine
does
differ
from
the
gasoline
engine,
however,
in
its
method
of
handling
and
firing
of
fuel.
The
carburetor
and
ignition
systems
are
replaced
by
a
single
component
-
the
fuel
injection
pump
-
which
performs
the
function
of
both.
ORDERING
PARTS
Whenever replacement parts are needed, always provide
the engine model number and serial number.
You
must
provide
us
with this information so
we
may properly iden-
tify your engine.
In
addition, include a complete part
description and part number for each part needed (see the
Parts List). Insist upon Westerbeke packaged parts
because
will
fit
or generic parts are frequently not made
to
the same specifications
as
original equipment.
SPARES
AND
ACCESSORIES
Certain spare parts will be needed to support and main-
tain your WESTERBEKE engine when cruising (see
SUGGESTED
SPARE
PARTS
KITS). Often even a
simple item such
as
a proper fuel filter can be difficult
to
obtain along the
way.
WESTERBEKE can provide
you with a suggested spares and accessories brochure
to
assist
you
in preparing
an
on-board inventory of the
proper WESTERBEKE parts.
PROTECTING
YOUR
INVESTMENT
Care
at
the
factory
during
assembly
and
thorough
testing
have
resulted
in
a
WESTERBEKE
engine
capable
of
many
thousands
of
hours
of
dependable
service.
However,
the
manufacturer
cannot
control
how
or
where
the
engine
is
installed
in
the
vessel
or
the
manner
in
which
the
unit
is
operated
and
ser-
viced
in
the
field.
This
is
up
to
the
buyer/owner-operator.
NOTE:
Six
important
steps
to
ensure
long
engine
life:
•
Proper
engine
installation.
•
An
efficient
well-designed
exhaust
system
that
includes
an
anti-siphon
break
to
prevent
water
from
entering
the
engine.
•
Changing
the
engine
oil
every
100
operating
hours.
•
Proper
maintenance
of
all
engine
components
according
to
the
maintenance
schedule
in
this
manual.
•
Use
clean,
filtered
diesel
fuel.
•
Wmterize
your
engine
according
to
the
LAY-UP
AND
RECOMMISSIONING
section
in
this
manual.
