Fuel, Engine Oil And Engine Coolant - Westerbeke 5.5 kw EDC 60 HZ Operator's Manual

DIESEL FUEL, ENGINE OIL AND ENGINE COOLANT
DIESEL FUEL
USE A DIESEL FUEL WITH A CETANE RATING DF 1145 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 importani 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.Insta1l 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.
ENGINE OIL
Use a heavy duty engine oil with
an
API classification of CP,
CG-4, CHA or CIA. 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 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.
SAE OIL VISCOSITY GRADES
For alilemperalures use SAE 10W-30 or 15W-40.
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
65 psi 2.5 and 3.9 kg/em').
NOTE: A newly started, cold engine can have an oil pressure
reading upwards of 60 psi (4.2 kg/em". A warmed engine can
have an oil pressure reading as low as 25 psi-{1.8 kg/em".
These readings will vary depending upon the temperature of
the engine, the load placed on the engine, and the
RPM~.
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 tbe
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
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 Glycol
(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.
Premixed antifreeze for DIESEL Engines:
Specification #ASTM D53456.
MAINTENANCE
Change the enigine, 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 ta11k, with its short run of plastic lwse, is best
located at or above the level of the engine
~
manifold, but it
can be located below the level of the engine~ manifold if the
particular installation makes this necessary.
