DIESEL FUEL, ENGINE OIL AND ENGINE COOLANT
DIESEL FUEL
USE A DIESEL FUEL WITH CETANE RATING OF #45 OR HIGHER.
(No. 2-D (SAE
J313)
diesel fuel according to ASTM D975).
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
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 diesel fuel. The use of
additives to combat BACTERIAL growth in the fuel tank
is recommended such as Bio-Bor and e such as Diesel
Kleen
+
cetane Boost to help restore lubricity back into the
diesel fuel when an Ultra Low Sulfur diesel is being used.
DO NOT use any additives containing ALCOHOL.
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 duiy engine oil with an API classification and
SAE as specified in the Specifications section of this manual
for the engine model you have. The engine oil and filter must
be changed after the 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 of
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 in the MAINTENANCE
SCHEDULE, not extended because synthetic oils are used.
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 may range from
25 psi (l.75 kg/cm
2 )
at idle upwards of 80 psi (5.6 kg/cm
2 )
at rated rpm.
NOTE:
A newly started, cold engine can have an oil pressure
reading up to 60 psi (4.2 kglcm
2 ).
A warmed engine can have
an oil pressure reading as low as 25 psi ( 1.8 kg!cm
2 ).
These
readings fvill vary dependinJ upon the temperature of the
engine and the load placed on the engine.
TRANSMISSION FLUID
Refer to the TRANSMISSJON SECTJON of this manual for
type of fluid and quantity for each transmission model.
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.
PURCHASING ANTIFREEZE
Select a brand of antifreeze specified for diesel engines.
Antifreeze specified for diesel engines contain a special
additive to protect against cavitation erosion of the engine's
cylinder walls. Prestone and Zerex are two nationally known
brands that offer antifreeze specifically for the use in diesel
engines. Select the pre-mix variety so that the correct mixture
will always be added to the cooling system when needed.
Change the antifreeze mixture according to the
MAJNTENANCE SCHEDULE in this manual.
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 have a limited life.
COOLANT RECOVERY TANK
A coolant recovery tank kit is supplied with each
engine. or generator. 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, 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.
