DIESEL
FUEL
Use fuel that meets the requirements
or
specification
of
Class
2-D (ASTM), and has a cetane rating
of
#45
or
hetter.
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 par-
ticles 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 unsatisfactory 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 filter/water
separator between the fuel tank and the engine.
The
Raycor
500 FG
or
900 FG are good
examples
of
sueh filters.
ENGINE
OIL
Use a heavy duty engine oil with an API classification
of
CF
or
CG-4
or
better. Change the engine oil after an initial 50
hours
of
break-in operation, and every 100 hours
of
operation
thereafter. For recommended oil viscosity, sec the following

A
CAUTION:
00
not allow
two
or
more
brands
of
engine
oil
to
mix.
Each
brand
contains
its
own
additives;
additives
of
different
brands
could react
in
the
mixture
to
produce
properties
hannful
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 35 and
55 psi.
NOTE:
A newly slarted, cold engine can have
an
oil pressure
reading upwards
of
60
psi. A warmed engine can have
an
oil
pressure reading as
low
as
25
psi. These readings will vary
depending upon the temperature
of
the engine
and
the load
placed on the generator.
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
(SeAs)
that keep the antifreeze chemically bal-
anced, 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

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
he
located at or above the engine:5 manifold
and
he
easily
accessible for checking
and
adding fluid.
