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:
A
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).
C
Fuel:
A
Cetane number of 45 minimum. Cetane number greater than 50 is preferred, especially for temperatures below
-20
or elevations above 1500 m.
A
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%.
A
NEVER use diesel fuel with sulfur content greater than 0.05% (500 ppm) for EXTERNAL EGR type engine.
A
DO NOT use diesel fuel with sulfur content greater than 1.0% (10000 ppm).
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.
C
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.
A
Indicated capacities of water and oil are manufacturer's estimate.
For other than North American market
A
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).

0.05% (500 ppm)]

(If the "CF-4, CG-4, CH-4 or CI-4" lubricating oil is
used with a high-sulfur fuel, change the lubricating
oil at shorter intervals. (approximately half))

Ultra Low Sulfur Fuel
[<0.0015% (15 ppm)]

A
The CJ-4 engine oil is intended for DPF (Diesel Particulate Filter) type engines, and cannot be used on this vehicle.
