DIESEL
FUEL
Use a diesel fuel that meets the requirements
of
No.
~-D
SAE J 313 and has a Cetane rating
of
#45 or higher grade
of
diesel fuel according to ASTM D975
Care
Of
The
Fuel
Supply
Use only clean diesel fuel! The clearance
of
the components
in your engines fuel injection pump
is
very critical; invisible
dirt particles which might pass through the primary and sec-
ondary filters can damage these finely machined 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 ensure 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. The use
of
additives
to combat BACTERIAL growth in the fuel tank is
recommended such as Bio-Bor and an additive such as
Diesel Kleen
+ Centane Boost to help restore lubricity back
into the diesel fuel when an Ultra Low Sulfur diesel
is
being
used.
Install and regularly service a good, visual-type fuel
filter/water separator between the fuel tank and the engine.
The Raycor
500 MA or 230 RMAM are good examples
of
such filters. A 10 micron filter element
is
recommended.
ENGINE
OIL
Use a heavy duty diesel oil with
an
API classification
of
CF,
CG-4, CH-4 or CI-4. Change the engine oil and filter after an
initial
50 hours
of
break-in operation.Then follow the oil and
filter change intervals as specified in the
MAINTENANCE
SCHEDULE
in this manual. Westerbeke Corporation does
not approve or disapprove the use
of
synthetic oils.
If
synthetic oils are used, engine break-in must be performed
using conventional oil.
Oil change intervals must be as listed
in the
MAINTENANCE
SCHEDULE
section
of
this
manual and not be extended if synthetic oils are used.
NOTE:
The information above supersedes all previous
statements regarding synthetic oil.

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.
PURCHASING
ANTIFREEZE
Rather than preparing the mixture, WESTERBEKE
recommends buying the premixed antifreeze so that so that
when adding coolant the mixture will always be correct.
There are two common types
of
antifreeze, Ethylene
G~ycol
(green) and Propylene Glycol (red/purple), either can be used
but do not mix the two and
if
changing from one to another,
flush the engine thoroughly.
Select a pre-mixed extendedUfe antifreeze specified for
use
in
diesel engines. Prestone
and
Zerex
both
offer this
type
of
antifreeze.
MAINTENANCE
Change the engine coolant every five years regardless
of
the
number
of
operating hours as the chemical additives that
protect and lubricate the engine
ha~e
a limited life.
COOLANT
RECOVERY
TANK
The coolant recovery tank allows for the expansion and
contraction
of
the engines coolant during engine operation
without introducing air into the system. This recovery
tank
is
provided with fresh water cooled models and with the fresh
water coolant conversion kit and must be installed before
operating the engine.
