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 engine oil according to the engine type (with
internal EGR, external EGR or non-EGR) and the fuel (low-sulfur or high-sulfur fuel).
Fuel used
High Sulfur Fuel
[≥ 0.05 % (500 ppm)]
Low Sulfur Fuel
[< 0.05 % (500 ppm)] or
Ultra Low Sulfur Fuel
[< 0.0015 % (15 ppm)]
EGR: Exhaust Gas re-circulation
• The CJ-4 engine oil is intended for DPF (Diesel Particulate Filter) type engines, and cannot be used on
this vehicle.
Model
Fuel
• Cetane number of 45 minimum. Cetane number greater than 50 is preferred, especially for temperatures
below −20 °C or elevations above 1500 m.
• If diesel fuel with sulfur content greater than 0.5 % (5000 ppm) sulfur content is used, reduce the service
interval for engine oil and filter by 50 %.
• NEVER use diesel fuel with sulfur content greater than 0.05 % (500 ppm) for EXTERNAL EGR type engine.
• DO NOT use diesel fuel with sulfur content greater than 1.0 % (10000 ppm).
• Diesel fuels specified to EN 590 or ASTM D975 are recommended.
• No.2-D is a distillate fuel of lower volatility for engines in industrial and heavy mobile service. (SAE J313
JUN87)
Transmission oil
• 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.
Do not mix different brands together.
Hydraulic tank oil:
• To insure proper operation of the hydraulic and VHT system, 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.
Do not mix different brands together.
Brake fluid:
• Always use KUBOTA DOT3 GENUINE BRAKE FLUID from a sealed container. If it is not available, you
should use only DOT3 fluid as a temporary replacement from a sealed container.
However, the use of any non-KUBOTA brake fluid can cause corrosion and decrease the life of the
system.
Have the brake system flushed and refilled with KUBOTA DOT3 GENUINE BRAKE FLUID as soon as
possible.
Indicated capacities of water and oil are manufacturer's estimate.
