120 MAINTENANCE
C Engine Oil:
A 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:
C Fuel:
A Use the ultra low sulfur diesel fuel only [below 0.0015% (15 ppm)] for these engines.
A Cetane number of 45 minimum. Cetane number greater than 50 is preferred, especially for temperatures below
-20 (-4 ) or elevations above 1500 m (5000 ft).
A Diesel fuels specified to EN 590 or ASTM D975 are recommended.
A No.2-D is a distillate fuel of lower volatility for engines in industrial and heavy mobile service. (SAE J313 JUN87)
C 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 UDT or SUPER UDT fluid for optimum protection and performance.
(Consult your local KUBOTA Dealer for further detail.)
Do not mix different brands together.
A Indicated capacities of water and oil are manufacturer's estimate.
A Refer to the following table for the suitable API classification engine oil according to the engine type (with DPF
(Diesel Particulate Filter) type engines) and the fuel.
