INTRODUCTION
SERIAL NUMBER LOCATION
An identification nameplate that displays the engine model
number and engine serial number is mounted on the side of
the engine's manifold. Take the time to enter this information
on the blank decal provided below. This will provide a quick
reference when seeking technical information and/or ordering
parts.

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 types of valves, camshaft, pistons,
connecting rods and lubricating system.
To a great extent, a diesel engine requires the same preven-
tive maintenance as a gasoline engine. Most important are
proper ventilation and proper maintenance of the fuel, lubri-
cating and cooling systems. Replacement of fuel and lubri-
cating filter elements at the time periods specified and
frequent checking for contamination (water, sediment, etc.) in
the fuel system are essentiaL Also important is the consistent
usc of a brand of high detergent diesel lubrication oil
designed specifically for diesel engines.
The diesel engine does differ from the gasoline engine, how-
ever, in its method of handling and firing of fuel. The carbu-
retor and ignition systems are done away with and in their
place is a single component (the fuel injection pump) which
pcrfonns the function of both.

ORDERING PARTS
Whenever replacement parts are needed, always provide the
engine model number and engine serial number
a,
they
appear on the silver and black identification nameplate
located on the manifold. You must provide us with this infor-
mation so we can identify your engine. In addition, include a
complete part description and part number for each part
needed (see the separately furnished Parts Catalog). Also
insist upon UNIVERSAUWESTERBEKE 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 UNIVERSAL marine engine. Your UNIVERSAU
WESTERBEKE dealer will assist you in preparing an on
board inventory of spare parts. See the UNIVERSAL SPARE
PARTS page in this manual for a suggested list.
PROTECTING YOUR INVESTMENT
Care at the factory during assembly and thorough testing
have resulted in a UNIVERSAL diesel 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 serviced in the field. This is up to the
buyer/owner-operator.
NOTE:
Six important sleps to ensure long engine bfe:
o
Proper engine installation and alignment.
o
An efficient well-designed exhaust system that includes
an anti-siphon break to prevent water from entering the
engine.
o
Changing the engine oil and oil filters every JOO operating
hours.
o
Proper maintenance of all engine components according
to the maintenance schedule in this manual.
o
Use clean. tiltered diesel fucl.
o
Winterize your engine according to the LAY-UP AND
RECOMMISSIONING
