Diesel Fuel,. Engine Oil And Coolant - Westerbeke 8.0KW - 60Hz Operator's Manual

DIESEL FUEL, ENGINE OIL AND ENGINE COOLANT
DIESEL FUEL
Use fuel that meets the requirements or speeification of Class
2-D (AS1M), 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 injeetion 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 fuel
filter/water separator between the fuel tank and the engine.
The Rayeor
225
or 500MA are good examples of such 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 reeommended oil viscosity, see the following
chart:
Operating TemperabJre 011 Viscosity
Above 68°F (20°C) SAE 30, 10W-30 or 15W-40
41 ° - 68°F (5 - 20°C) SAE 20, 10W-30 or 1SW-40
Below 41°F (SOC)
SAE 10W-30 or 15W-40
A
CAUTION:
Do not allow two or more brands of
engine oil to mix. Each brand contains Its own additives;
additives of diffefent brands could feact in the mixture
to produce properties 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
nonnal operation, the oil pressure will range between 35 and
55 psi (2.5 and 3.9 kg/cm
2
).
NOTE: A newly started, cold engine can have an oil pressure
reading up to 60 psi (4.2 kg!cm2). A wanned engine can have
an oil pressure reading as low as 25 psi (1.8 kglcm
2
).
These
readings will vary depending upon the temperature of the
engine, the load placed on the engine, and the RPM's.
ENGINE COOLANT
WESTERBEKE reeommends a mixture of 50% antifreeze
and 50% distilled water. Distilled water is free from the
chemicals that can corrode internal engine surfaces.
The antifreeze perfonns 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 tenn 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.

COOLANT 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 slwrt run of plastic hose, is best
located at or above the level of the engine's manifold, but it
can be located below the level of the engine's manifold if the
particular installation makes this necessary.
