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 compo-
nents in your fuel injection pump is very critical; invisi-
ble 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
ren-
dered 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 filterl
water separator between the fuel tank and the engine.
Raycor 500
FG
or
900 FG is a good example
of
such
a filter.
ENGINE
OIL
Use a heavy duty engine oil with an API classification
of
CF or CG4 or better. Change the engine oil after an
initial 50 hours
of
break-in operation, and every 200 hours
of
operation thereafter. For recommended oil viscosity,
see the following chart:

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
harmful
to
your
engine.

ENGINE
COOLANT
The use
of
an antifreeze mixture
of
50/50 is recom-
mended for year-round use. Use antifreeze that is com-
patible with aluminium components, and never mix
different brands
of
antifreeze. Do not use straight water,
this can
be
detrimental to the cooling system compo-
nents.
NOTE:
Lookfor
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 circu-
lating pump seal.

COOLANT
RECOVERY
TANK
A coolant recovery tank kit is supplied with each
WESTERBEKE diesel engine. The purpose
of
this re-
covery 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.
