INTRODUCTION 
SERIAL 
NUMBER 
LOCATION 
The 
engine's model number and serial number are located 
on 
the nameplate mounted 
on 
the side 
of 
the 
engine's water 
jacketed exhaust manifold. The engine's serial number 
is 
stamped 
in 
the engine block on the right rear side just above 
the side oil fill. Enter this information 
on 
the illustration 
of 
the nameplate below. Use it for a quick reference when needed. 
Fill 
in 
the 
information for your 
referance. 
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 
the 
same general type 
as 
that of a gasoline engine, and the diesel 
engine 
has 
the same 
types 
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. 
Fuel and lubricating filter elements must 
be 
replaced 
at 
the 
time periods specified and frequent checking for 
contaminations 
(water, 
sediment, etc.) 
in 
the 
fuel 
system 
is 
also essential. Another important factor 
is 
the 
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 
engine serial number 
as 
they 
appear 
on 
the silver and black name plate located 
on 
the 
manifold. 
You 
must provide 
us 
with this information 
so 
we 
may 
properly identify your engine. 
In 
addition, 
include 
a 
complete part description and part number 
for 
each part 
needed 
(see 
the 
separately furnished 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 spares 
will 
be 
needed 
to 
support and maintain your 
WESTERBEKE engine. 
Your 
local WESTERBEKE dealer 
will 
assist 
you 
in 
preparing 
an 
inventory of spare 
parts.
