DIESEL
FUEL
Use fuel that meets the requirements
or
specification
of
Class
2-D (ASTM), and has a cetane rating
of
#45 or better.
Care
Of
The
Fuel
Supply
Use only clean diesel fuel! The clearance
of
the components
in your fuel injection pump
is
very critical; invisible dirt
particles which might pass through the filter can damage
these finely finished parts. It
is
important to buy clean fuel,
and keep it clean. The best fuel can be rendered unsatisfac-
tory by careless handling or improper storage facilities.
To
assure that the fuel going into the tank for your engine's daily
use
is
clean and pure, the following practice
is
advisable:
Purchase a well-known brand
of
fuel.
Install and regularly service a good, visual-type fuel
filter/water separator between the fuel tank and the engine.
The Raycor 445 or larger
is
a good example
of
such a filter.

Use the heavy duty engine oils as specified above. Change
the engine oil after
an
initial
50
hour break-in period and
every
100 hours
of
operation thereafter.
Engine oil viscosity largely affects engine startability, perfor-
mance, oil consumption, speed
of
wearing and occurrence
of
seizure, etc. Using lubricants whose viscosity
is
selected
according to the atmospheric temperature
is
important.

A
CAUTION:
Do
not
allow
two
or
more
brands
of
engine
oil
to
mix.
Each
brand
contains
its
own
additives;
additives
of

brands
could

mixture
to
produce

harmful
to
your
engine.
OIL
PRESSURE
The engine's oil pressure, during operation, is indicated
by the oil pressure gauge on the instrument panel. During
normal operation, the oil pressure will range between 25 and
85 psi.
NOTE:
A newly staned, cold engine can have an oil pressure
reading up to
85
psi. A warmed engine can have an oil pres-
sure reading as low as
25
psi. These readings will vary
depending upon the temperature
of
the engine, the load
placed on the engine,
and
the RPM's.
ENGINE
COOLANT
WESTERBEKE recommends a mixture
of
50% antifreeze
and
50% distilled water. Distilled water
is
free from the
chemicals that can corrode internal engine surfaces.
The antifreeze performs double duty. It allows the engine to
run at proper temperatures by transferring heat away from the
engine to the coolant, and lubricates and protects the cooling
circuit from rust and corrosion. Look for a good quality
antifreeze that contains Supplemental Cooling Additives
(SCAs) that keep the antifreeze chemically balanced, crucial
to long term protection.
The distilled water and antifreeze should be premixed before
being poured into the cooling circuit.
NOTE:
Look
for
the new environmentally-friendly long lasting
antifreeze that
is now available.
Antifreeze mixtures will protect against an unexpected freeze
and they are beneficial to the engine's cooling system. They
retard rust and add to the life
of
the circulating pump seal.

RECOVERY
TANK
A coolant recovery tank kit
is
supplied with each
WESTERBEKE diesel engine. The purpose
of
this recovery
tank
is
to allow for engine coolant expansion and contraction
during engine operation, without the loss
of
coolant and
without introducing air into the cooling system. This
kit
is
provided and must be installed before operating the engine.
NOTE:
This tank, with its short run
of
plastic hose, must be
located above the level
of
the engine's manifold.
