G GENERAL
• NOTE
Engine Oil :
• Oil used in the engine should have an American Petroleum Institute (API) service classification and Proper
SAE Engine Oil according to the ambient temperatures as shown above:
• With the emission control now in effect, the CF-4 and CG-4 lubricating oils have been developed for use
of a low-sulfur fuel on on-road vehicle engines. When an off-road vehicle engine runs on a high-sulfur fuel,
it is advisable to employ the "CF or better" lubricating oil with a high Total Base Number (TBN of
10 minimum).
• Refer to the following table for the suitable API classification of engine oil according to the Fuel: (Low
Sulfur or High Sulfur Fuels).
Fuel used Engine oil classification (API classification)
High Sulfur Fuel
(2: 500 ppm)
CF
(If the "CF-4, CG-4, CH-4, or CI-4ft lubricating oil is used with a high-sulfur fuel. change
the lubricating oil at shorter intervals. (approximately half))
Low Sulfur Fuel
« 500 ppm) or Ultra
Low Sulfur Fuel «
15 ppm)
CF, CF-4, CG-4, CH-4 or CI-4
• The CJ-4 engine oil is intended for DPF (Diesel Particulate Filter) type engines, and cannot be used on this
tractor.
Fuel:
• Cetane number of 45 minimum. Cetane number greater than 50 is preferred, especially for temperatures
below -20°C (-4 OF) or elevations above 1500 m (5000 tt).
• If diesel sulfur content greater than 0.5
%
sulfur content is used, reduce the service interval for engine oil
and filter by 50
%.
• DO NOT use diesel fuel with sulfur content greater than 1.0 %.
• Diesel fuels specified to EN 590 or A5TM 0975 are recommended.
• No.2-o is a distillate fuel of lower volatility for engines in industrial and heavy mobile service. (5AE J313
JUN87)
• Since this engine adopts EPA Tier 4 and Interim Tier 4 standards, the use of low sulfur fuel or ultra low
sulfur fuel is mandatory in EPA regulated area (North America). Therefore, please use No.2-D 5500 or 515
diesel fuel as an alternative to No.2-o, or use No.1-D 5500 or 515 diesel fuel as an alternative to No.1-D if
outside air temperature is below -10°C (14 OF).
Transmission Oil:
The oil used to lubricate the transmission is also used as hydraulic fluid. To insure proper operation of
the hydraulic system and to complete lubrication of the transmission, it is important that a multi-grade
transmission fluid is used in this system. We recommend the use of KUBOTA UoT or SUPER UDT fluid for
optimum protection and performance. (Consult your local KUBOTA Dealer for further detail.)
Do not mix different brands together.
• Indicated capacities of water and oil are manufacturer's estimate.
