SAFETY INSTRUCTIONS
SAFETY STARTING
• Do not start the engine by shorting across starter
terminals or bypassing the safety start switch.
• Unauthorized modifications to the engine may impair
the function and / or safety and affect engine life.
SAFETY WORKING
• Do not work on the machine while under the influence
of alcohol, medication, or other substances or while
fatigued.
• Wear close fitting clothing and safety equipment
appropriate to the job.
• Use tools appropriate to the work. Makeshift tools,
parts, and procedures are not recommended.
• When servicing is performed together by two or more
persons, take care to perform all work safely.
• Do not touch the rotating or hot parts while the engine
is running.
• Never remove the radiator cap while the engine is
running, or immediately after stopping. Otherwise, hot
water will spout out from radiator. Only remove
radiator cap when cool enough to touch with bare
hands. Slowly loosen the cap to first stop to relieve
pressure before removing completely.
• Escaping fluid (fuel or hydraulic oil) under pressure
can penetrate the skin causing serious injury. Relieve
pressure before disconnecting hydraulic or fuel lines.
Tighten all connections before applying pressure.
• Wear a suitable hearing protective device such as
earmuffs or earplugs to protect against objectionable
or uncomfortable loud noises.
AVOID FIRES
• Fuel is extremely flammable and explosive under
certain conditions. Do not smoke or allow flames or
sparks in your working area.
• To avoid sparks from an accidental short circuit,
always disconnect the battery negative cable first and
connect it last.
• Battery gas can explode. Keep sparks and open
flame away from the top of battery, especially when
charging the battery.
• Make sure that no fuel has been spilled on the engine.

SAFETY INSTRUCTIONS
VENTILATE WORK AREA
• If the engine must be running to do some work, make
sure the area is well ventilated. Never run the engine
in a closed area. The exhaust gas contains poisonous
carbon monoxide.
DISPOSE OF FLUIDS PROPERLY
• Do not pour fluids into the ground, down a drain, or
into a stream, pond, or lake. Observe relevant
environmental protection regulations when disposing
of oil, fuel, coolant, electrolyte and other harmful
waste.
PREVENT ACID BURNS
• Sulfuric acid in battery electrolyte is poisonous. It is
strong enough to burn skin, clothing and cause
blindness if splashed into eyes. Keep electrolyte
away from eyes, hands and clothing. If you spill
electrolyte on yourself, flush with water, and get
medical attention immediately.
PREPARE FOR EMERGENCIES
• Keep a first aid kit and fire extinguisher handy at all
times.
• Keep emergency numbers for doctors, ambulance
service, hospital and fire department near your
telephone.

[2] E2B ENGINE
[ex. Model Name D1105-E2B]
The emission controls that have been put into effect in various countries to prevent air pollution will be stepped up.
The time to enforce the regulations differs depending on the engine output classifications.
Kubota has been supplying the diesel engines conforming to the emission regulations in respective countries.
Exhaust emissions regulations shift to the second stage. Kubota executed the improvement of the engine according
to this regulation.
In order to discriminate the engines conforming to Tier 1 / Phase 1 requirements and those conforming to Tier 2 /
Phase 2 requirements, we have adopted E2B as a new model name for the engines conforming Tier 2 / Phase 2
regulations.
In the after-sale services for 05-E2B and 05-E2BG series engines, only use the dedicated parts for E2B models
and carry out the maintenance services accordingly.
[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.

2. GENERAL PRECAUTIONS
• During disassembly, carefully arrange removed parts in a clean
area to prevent confusion later. 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.

Q NOTE
Lubricating Oil
With the emission control now in effect, the CF-4 and CG-4 lubricating oils have been developed for use of a lowsulfur fuel on-road vehicle engines. When an off-road vehicle engine runs on a high-sulfur fuel, it is advisable to
employ the CF, CD or CE lubricating oil with a high total base number. If the CF-4 or CG-4 lubricating oil is used with
a high-sulfur fuel, change the lubricating oil at shorter intervals.
• Lubricating oil recommended when a low-sulfur or high-sulfur fuel is employed.

[1] DAILY CHECK POINTS
Checking Engine Oil Level
1. Level the engine.
2. To check the oil level, draw out the dipstick (1), wipe it clean,
reinsert it, and draw it out again.
Check to see that the oil level lies (A) between the two notches.
3. If the level is too low, add new oil to the specified level.
• When using an oil of different maker or viscosity from the
previous, drain old oil. Never mix two different types of oil.
• Be sure to inspect the engine, locating it on a horizontal
place. If placed on gradients, accurately, oil quantity may
not be measured.
• Be sure to keep the oil level between upper and lower limits
of the dipstick. Too much oil may cause a drop in output or
excessive blow-by gas. On the closed breather type engine
in which mist is sucked through port, too much oil may
caused oil hammer. While too little oil, may seize the
engine’s rotating and sliding parts.

Checking and Replenish Coolant
1. Without recovery tank :
Remove the radiator cap (1) and check to see that the coolant
level is just below the port.
With recovery tank (2) :
Check to see that the coolant level lies between FULL (A) and
LOW (B).
2. If coolant level is too low, check the reason for decreasing
coolant.
(Case 1)
If coolant is decreasing by evaporation, replenish only fresh, soft
water.
(Case 2)
If coolant is decreasing by leak, replenish coolant of the same
manufacture and type in the specified mixture ratio (fresh, soft
water and L.L.C.). If the coolant brand cannot be identified, drain
out all of the remaining coolant and refill with a totally new brand
of coolant mix.
• Do not remove the radiator cap until coolant temperature is
below its boiling point. Then loosen the cap slightly to
relieve any excess pressure before removing the cap
completely.
• During filling the coolant, air must be vented from the engine
coolant passages. The air vents by jiggling the radiator
upper and lower hoses.
• Be sure to close the radiator cap securely. If the cap is loose
or improperly closed, coolant may leak out and the engine
could overheat.
• Do not use an antifreeze and scale inhibitor at the same time.
• Never mix the different type or brand of L.L.C..
