ENGINE
Engine Serial Number Plate
Each engine has a 13–digit engine serial
number.
The engine’s serial number plate is located on
the right–hand side of cylinder block behind the
fuel filter.
Fuels, Lubricants, and Coolant
Diesel Fuel
Consult your local fuel distributor for properties
of the diesel fuel available in your area.
In general, diesel fuels are blended to satisfy
the low temperature requirements of the
geographical area in which they are marketed.
Diesel fuels specified to EN 590 or ASTM D975
are recommended.
Required fuel properties
In all cases, the fuel must meet the following
properties:
Cetane number of 45 minimum. Cetane
number greater than 50 is preferred, especially
for temperatures below –20
_ C (–4 _ F) or
elevations above 1500 m (5000 ft).
Cold Filter Plugging Point (CFPP) below the
expected low temperature OR Cloud Point at
least 5
_ C (9 _ F) below the expected low
temperature.
Fuel lubricity should pass a minimum load
level of 3100 grams as measured by ASTM
D6078 or, maximum scar diameter of 0.45 mm
as measured by ASTM D6079.
Sulfur content:
•
Diesel fuel quality and fuel sulfur content must
comply with all existing regulations for the area
in which the engine operates.
•
Sulfur content less than 0.05% (500 ppm) is
preferred.
•
If diesel fuel with sulfur content greater than
0.05% (500 ppm) is used, crankcase oil service
intervals may be affected. (See
recommendation for Diesel Engine Oil.)
•
DO NOT use diesel fuel with sulfur content
greater than 1.0%.
IMPORTANT: DO NOT mix used engine oil or
any other type of lubricating oil with diesel
fuel.
Bio–Diesel Fuel
Bio–diesel fuels may be used ONLY if the
bio–diesel fuel properties meet the latest edition
of ASTM PS121, DIN 51606 or equivalent
specification.
It has been found that bio–diesel fuels may
improve lubricity in concentrations up to a 5%
blend in petroleum diesel fuel.
When using a blend of bio–diesel fuel, the
engine oil level must be check daily when the air
temperature is –10
_ C (14 _ F) or lower. If the oil
becomes diluted with fuel, shorten oil change
intervals accordingly.
IMPORTANT: Raw pressed vegetable oils
are NOT acceptable for use for fuel in any
concentration.
These oils do not burn completely, and will
cause engine failure by leaving deposits on
injectors and in the combustion chamber.
Handing and Storing Bio–Diesel Fuel
WARNING: Handle fuel carefully. Do not fill
the fuel tank when engine is running.
DO NOT smoke while you fill the fuel tank or
service the fuel system.
Fill the fuel tank at the end of each day’s
operation to prevent water condensation and
freezing during cold weather.
Keep all storage tanks as full as practicable to
minimize condensation.
Ensure that all fuel tank caps and covers are
installed properly to prevent moisture from
entering.
Monitor water content of the fuel regularly.
Fuel filter may require more frequent
replacement due to premature plugging.
Check engine oil level daily prior to starting
engine. A rising oil level may indicate fuel
dilution of the engine oil.
When fuel is stored for an extended period or if
there is a slow turnover of fuel, add a fuel
conditioner to stabilize the fuel and prevent
water condensation. Contact your fuel supplier
for recommendations.
