[2] E3B ENGINE
[Example : Engine Model Name D1105-E3B-XXXX]
The emission controls previously implemented in various countries to prevent air pollution will be stepped up as
Non-Road Emission Standards continue to change. The timing or applicable date of the specific Non-Road Emission
regulations depends on the engine output classification.
Over the past several years, Kubota has been supplying diesel engines that comply with regulations in the
respective countries affected by Non-Road Emission regulations. For Kubota Engines, E3B will be the designation
that identifies engine models affected by the next emission phase (See the table below).
When servicing or repairing ###-E3B series engines, use only replacement parts for that specific E3B engine,
designated by the appropriate E3B Kubota Parts List and perform all maintenance services listed in the appropriate
Kubota Operator's Manual or in the appropriate E3B Kubota Workshop Manual. Use of incorrect replacement parts
or replacement parts from other emission level engines (for example: E2B engines), may result in emission levels out
of compliance with the original E3B design and EPA or other applicable regulations.Please refer to the emission label
located on the engine head cover to identify Output classification and Emission Control Information. E3B engines are
identified with "ET" at the end of the Model designation, on the US EPA label. Please note : E3B is not marked on the
engine.

CAUTION
• When changing or inspecting, be sure to level and stop the engine.
■ NOTE
Engine Oil :
• Refer to the following table for the suitable American Petroleum Institute (API) classification of engine oil
according to the engine type (with internal EGR, external EGR or non-EGR) and the Fuel Type Used :
(Low Sulfur, Ultra Low Sulfur or High Sulfur Fuels).
EGR : Exhaust Gas Re-circulation
W1024941
• CJ-4 classification oil is intended for use in engines equipped with DPF (Diesel Particulate Filter) and is
Not Recommended for use in Kubota E3 specification engines.
• Oil used in the engine should have API classification and Proper SAE Engine Oil Viscosity according to
the ambient temperatures where the engine is operated.
• With strict emission control regulations now in effect, the CF-4 and CG-4 engine oils have been developed
for use with low sulfur fuels, for On-Highway vehicle engines. When a Non-Road engine runs on high
sulfur fuel, it is advisable to use a "CF or better" classification engine oil with a high Total Base Number
(a minimum TBN of 10 is recommended).
Fuel :
• Cetane Rating : The minimum recommended Fuel Cetane Rating is 45. A cetane rating greater than 50 is
preferred, especially for ambient temperatures below −20 °C (−4 °F) or elevations above 1500 m (5000 ft).
• Diesel Fuel Specification Type and Sulfur Content % (ppm) used, must be compliant with all applicable
emission regulations for the area in which the engine is operated.
• Use of diesel fuel with sulfur content less than 0.10 % (1000 ppm) is strongly recommended.
• If high-sulfur fuel (sulfur content 0.50 % (5000 ppm) to 1.0 % (10000 ppm)) is used as a diesel fuel, change
the engine oil and oil filter at shorter intervals. (approximately half)
• DO NOT USE Fuels that have 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)
• Since KUBOTA diesel engines of less than 56 kW (75 hp) utilize EPA Tier 4 and Interim Tier 4 standards,
the use of low sulfur fuel or ultra low sulfur fuel is mandatory for these engines, when operated in US EPA
regulated areas. Therefore, please use No.2-D S500 or S15 diesel fuel as an alternative to No.2-D, and use
No.1-D S500 or S15 diesel fuel as an alternative to No.1-D for ambient temperatures below −10 °C (14 °F).
1) SAE : Society of Automotive Engineers
2) EN : European Norm
3) ASTM : American Society of Testing and Materials
4) US EPA : United States Environmental Protection Agency
5) No.1-D or No.2-D, S500 : Low Sulfur Diesel (LSD) less than 500 ppm or 0.05 wt.%

G-3 05-E3B, 05-E3BG, WSM G GENERAL [2] E3B ENGINE [Example : Engine Model Name D1105-E3B-XXXX] The emission controls previously implemented in various countries to prevent air pollution will be stepped up as Non-Road Emission Standards continue to change. The timing or applicable date of the specific Non-Road Emission regulations depends on the engine output classification. Over the past several years, Kubota has been supplying diesel engines that comply with regulations in the respective countries affected by Non-Road Emission regulations. For Kubota Engines, E3B will be the designation that identifies engine models affected by the next emission phase (See the table below). When servicing or repairing ###-E3B series engines, use only replacement parts for that specific E3B engine, designated by the appropriate E3B Kubota Parts List and perform all maintenance services listed in the appropriate Kubota Operator's Manual or in the appropriate E3B Kubota Workshop Manual. Use of incorrect replacement parts or replacement parts from other emission level engines (for example: E2B engines), may result in emission levels out of compliance with the original E3B design and EPA or other applicable regulations.Please refer to the emission label located on the engine head cover to identify Output classification and Emission Control Information. E3B engines are identified with "ET" at the end of the Model designation, on the US EPA label. Please note : E3B is not marked on the engine. W1031971 [3] CYLINDER NUMBER The cylinder numbers of KUBOTA diesel engine are designated as shown in the figure. The sequence of cylinder numbers is given as No.1, No.2, No.3 and No.4 starting from the gear case side.

Screws, bolts and nuts should be replaced in their original position to prevent reassembly errors. • When special tools are required, use KUBOTA genuine special tools. Special tools which are not frequently used should be made according to the drawings provided. • Before disassembling or servicing live wires, make sure to always disconnect the grounding cable from the battery first. • Remove oil and dirt from parts before measuring. • Use only KUBOTA genuine parts for parts replacement to maintain engine performance and to ensure safety. • Gaskets and O-rings must be replaced during reassembly. Apply grease to new O-rings or oil seals before assembling. • When reassembling external or internal snap rings, position them so that the sharp edge faces against the direction from which force is applied. • Be sure to perform run-in the serviced or reassembled engine. Do not attempt to give heavy load at once, or serious damage may result to the engine.

G-6 05-E3B, 05-E3BG, WSM G GENERAL CAUTION • When changing or inspecting, be sure to level and stop the engine. ■ NOTE Engine Oil : • Refer to the following table for the suitable American Petroleum Institute (API) classification of engine oil according to the engine type (with internal EGR, external EGR or non-EGR) and the Fuel Type Used : (Low Sulfur, Ultra Low Sulfur or High Sulfur Fuels). EGR : Exhaust Gas Re-circulation W1024941 • CJ-4 classification oil is intended for use in engines equipped with DPF (Diesel Particulate Filter) and is Not Recommended for use in Kubota E3 specification engines. • Oil used in the engine should have API classification and Proper SAE Engine Oil Viscosity according to the ambient temperatures where the engine is operated. • With strict emission control regulations now in effect, the CF-4 and CG-4 engine oils have been developed for use with low sulfur fuels, for On-Highway vehicle engines. When a Non-Road engine runs on high sulfur fuel, it is advisable to use a "CF or better" classification engine oil with a high Total Base Number (a minimum TBN of 10 is recommended). Fuel : • Cetane Rating : The minimum recommended Fuel Cetane Rating is 45. A cetane rating greater than 50 is preferred, especially for ambient temperatures below −20 °C (−4 °F) or elevations above 1500 m (5000 ft). • Diesel Fuel Specification Type and Sulfur Content % (ppm) used, must be compliant with all applicable emission regulations for the area in which the engine is operated. • Use of diesel fuel with sulfur content less than 0.10 % (1000 ppm) is strongly recommended. • If high-sulfur fuel (sulfur content 0.50 % (5000 ppm) to 1.0 % (10000 ppm)) is used as a diesel fuel, change the engine oil and oil filter at shorter intervals. (approximately half) • DO NOT USE Fuels that have 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) • Since KUBOTA diesel engines of less than 56 kW (75 hp) utilize EPA Tier 4 and Interim Tier 4 standards, the use of low sulfur fuel or ultra low sulfur fuel is mandatory for these engines, when operated in US EPA regulated areas. Therefore, please use No.2-D S500 or S15 diesel fuel as an alternative to No.2-D, and use No.1-D S500 or S15 diesel fuel as an alternative to No.1-D for ambient temperatures below −10 °C (14 °F). 1) SAE : Society of Automotive Engineers 2) EN : European Norm 3) ASTM : American Society of Testing and Materials 4) US EPA : United States Environmental Protection Agency 5) No.1-D or No.2-D, S500 : Low Sulfur Diesel (LSD) less than 500 ppm or 0.05 wt.% No.1-D or No.2-D, S15 : Ultra Low Sulfur Diesel (ULSD) 15 ppm or 0.0015 wt.% Fuel Type Engine oil classification (API classification) Engines with non-EGR Engines with internal EGR Engines with external EGR High Sulfur Fuel [0.05 % (500 ppm) ≤ Sulfur Content < 0.50 % (5000 ppm)] CF (If the "CF-4, CG-4, CH-4, or CI-4" engine oil is used with a high-sulfur fuel, change the engine oil at shorter intervals.
