[2] E2B ENGINE

[ex.: Model Name V3300-E2B-XXXX]
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 1
Phase 2 requirements, we have adopted E2B as a new model name for the engines conforming Tier 2 I Phase 2
regulations.
In the after-sale services for V3300-E2B and V3300-T-E2B series engines, only use the dedicated parts for E2B
models and carry out the maintenance services accordingly.

A CAUTION
• When changing or inspecting, be sure to level and stop the engine.
HI 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 low-
sulfur 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.

4. CHECK AND MAINTENANCE

[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 between the two notches.
3. If the level is too low, add new oil to the specified level.
■ IMPORTANT
• When using an oil of different maker or viscosity from the
previous, drain old oil. Never mix two different types of
S E E A B A B IP O IS /r^E n 1
oil.
■ NOTE
• 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.

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.
A CAUTION
3EEABAB1P015D
• 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.
■ IMPORTANT
• 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.

Cleaning Water Jacket and Radiator Interior

A CAUTION
• Do not remove the radiator cap when the engine is hot.
Then loosen cap slightly to the stop to relieve any excess
pressure before removing cap completely.
1. Stop the engine and let cool down.
2. To drain the coolant, open the radiator drain plug (2) and
remove the radiator cap (1). Then radiator cap (1) must be
removed to completely drain the coolant. And open the drain
cock (3).
3. After all coolant is drained, close the drain plug.
4. Fill with clean water and cooling system cleaner.
5. Follow directions of the cleaner instruction.
6. After flushing, fill with clean water and anti-freeze until the
coolant level is just below the port. Install the radiator cap (1)
securely.
7. Fill with coolant up to "FULL" (A) mark on the recovery tank
(4).
8. Start and operate the engine for few minutes.
3EEABAB1P032A
9. Stop the engine and let cool. Check coolant level of radiator
and recovery tank (4) and add coolant if necessary.
■ IMPORTANT
• Do not start engine without coolant.
• Use clean, fresh, soft water and anti-freeze to fill the
radiator and recovery tank.
• When the anti-freeze is mixed with fresh, soft water, the
anti-freeze mixing ratio must be less than 50 %.
• Securely tighten radiator cap. If the cap is loose or
improperly fitted, water may leak out and the engine could

Anti-Freeze
• There are two types of anti-freeze available: use the
permanent type (PT) for this engine.
• Before adding anti-freeze for the first time, clean the radiator
interior by pouring fresh, soft water and draining it a few times.
® The procedure for mixing water and anti-freeze differs
according to the make of the anti-freeze and the ambient
temperature. Basically, it should be referred to SAE J1034
standard, more specifically also to SAE J814c.
• Mix the anti-freeze with fresh, soft water, and then fill into the
radiator.
■ IMPORTANT
• When the anti-freeze is mixed with fresh, soft water, the
anti-freeze mixing ratio must be less than 50 %.

*At 1.013 x 1000000 Pa (760 mmHg) pressure (atmospheric).

A higher boiling point is obtained by using a radiator pressure cap
which permits the development of pressure within the cooling
system.
■ NOTE
• The above data represents industrial standards that
necessitate a minimum glycol content in the concentrated
anti-freeze.
• When the coolant level drops due to evaporation, add
fresh, soft water only to keep the anti-freeze mixing ratio
less than 50 %. In case of leakage, add anti-freeze and
fresh, soft water in the specified mixing ratio.
• Anti-freeze absorbs moisture. Keep unused anti-freeze in
a tightly sealed container.
• Do not use radiator cleaning agents when anti-freeze has
been added to the coolant.
(Anti-freeze contains an anti-corrosive agent, which will
react with the radiator cleaning agent forming sludge
which will affect the engine parts.)

Recharging
△ CAUTION
® When the battery is being activated, hydrogen and
oxygen gases in the battery are extremely explosive.
Keep open sparks and flames away from the battery at ail
times, especially when charging the battery.
• When charging battery, remove battery vent plugs.
• When disconnecting the cable from the battery, start with
the negative terminal first. When connecting the cable to
the battery, start with the positive terminal first.
• Never check battery charge by placing a metal object
across the posts.
• Use a voltmeter or hydrometer.
1) Slow Charging
1. Add distilled water if the electrolyte level is low. When
charging, the amount of electrolyte should be slightly lower
than the specified level to prevent overflow.
2. Connect the battery to the charging unit, following the
manufacture's instructions.
3. As the electrolyte generates gas while charging, remove all
port caps.
4. The electrolyte temperature must not exceed 40 °C (105 °F)
during charging.
If it exceed 40 °C (105 °F), decrease the charging amperage
or stop charging for a while.
5. When charging several batteries in series, charge at the rate
of the smallest battery in the line.
2) Quick Charging
1. Determine the proper charging current and charging time with
the tester attached to the quick charger.
2. Determine the proper charging current as 1/1 of the battery
capacity. If the battery capacity exceeds 50 Ah, consider 50 A
as the maximum.
■ Precaution for Operating a Quick Charger
• Operation with a quick charger differs according to the type.
Consult the instruction manual and use accordingly.

Battery Specific Gravity

1. Check the specific gravity of the electrolyte in each cell with a
hydrometer.
2. When the electrolyte temperature differs from that at which the
hydrometer was calibrated, correct the specific gravity reading
following the formula mentioned in (Reference).
3. If the specific gravity is less than 1.215 (after it is corrected for
temperature), charge or replace the battery.
4. If the specific gravity differs between any two cells by more
than 0.05, replace the battery.
■ NOTE
• Hold the hydrometer tube vertical without removing it
from the electrolyte.
• Do not suck too much electrolyte into the tube.
• Allow the float to move freely and hold the hydrometer at
eye level.
• The hydrometer reading must be taken at the highest
electrolyte level.

(Reference)
• Specific gravity slightly varies with temperature. To be exact,
the specific gravity decreases by 0.0007 with an increase of
1 °C (0.0004 with an increase of 1 °F) in temperature, and
increases by 0.0007 with a decreases of 1 °C (0.0004 with a
decrease of 1 °F).
Therefore, using 20 °C (68 °F) as a reference, the specific
gravity reading must be corrected by the following formula :
-Specific gravity at 20 °C = Measured value + 0.0007 x
(electrolyte temperature - 20 °C)
-Specific gravity at 68 °F = Measured value + 0.0004 x
(electrolyte temperature - 68 °F)

Directions for Storage

1. When shutting down the tractor for long periods of time,
remove the battery from the tractor, adjust the electrolyte to
the proper level, and after fully charging, store the battery in a
well ventilated placed where it is not exposed to direct
sunlight.
2. Since the battery self-discharges by approx. 0.5 % per day
even in storage, it must be once every two months in cold
season.
3. When storaging the battery mounted on the tractor, disconnect
the ground cable from the battery's negative terminal post.

1. FEATURE
V3 series IDI engine is the vertical type 4-cycle diesel
V3300-E2B engine featuring the advanced performances shown
below.
This is a small sized, high power and environment
conscious engine, which employs the three valve
system, two inlet valves and double ports, and one
exhaust valve and the new E-TVCS VERSION-II.
Thus, this engine achieves high combustion efficiency
and complies with various regulations of exhaust gas.
Based upon the conventional model, Kubota
developed a unique governor system and various new
mechanisms which reduces exhaust emission, noise
and vibration and realize durability and high torque.

2. ENGINE BODY
[1] CYLINDER BLOCK
This engine employs separate type crankcases - the
crankcase 1 with combustion part and the crankcase 2
which supports the crankcase 1 and reduces noise.
Since it is a hanger type, you can easily assemble I
disassemble it. The cylinder is a linerless type which
enables good cooling operation, less strain and good
abrasion resistance.

[3] CYLINDER HEAD

This engine employs three valve system - two inlet
valves and double ports, and one exhaust valve which
produce good inlet inertia to improve combustion
efficiency and volumetric efficiency. It also employs
Kubota's unique combustion chamber with multiple
injection grooves.
Besides the conventional cross port system, it
employs the forced cooling method between valves to
eliminate heat distortion, thus enabling durable and
reliable configuration.
0000004840E

[4] PISTON AND PISTON RINGS

This engine employs the E-TVCS VERSION-II so that
the improved combustion surface at the top of piston
enables more complete combustion efficiency than the
conventional models.
The profile and the offset of piston are optimized to
reduce slapping noises. The oil jet at the small end of
the connecting rod reduces heat load of the piston.
Three rings are installed in grooves in the piston. The
top ring (1) is made of nitrizing steel to get more
reliability than the chrome plated ring. It is a keystone
type ring to get durability against heavy load. At the
sliding part, a special piston ring which is conformable
3EEAAAA1P024A
to the cylinder wall is employed. The second ring is
chromeplated on the peripheral surface and it is an
undercut ring to prevent shortage of oil.
The oil ring (3) has chamfered contact faces and an
expander ring, which increase the pressure of the oil
ring against the cylinder wall.
Several grooves are cut on the topland to help heat
dissipate and to prevent scuffing.

[5] BUILT-IN DYNAMIC BALANCER (BALANCER MODEL ONLY)

Engine are sure to vibrate by piston's reciprocation.
Theoretically, three-cylinder engines are much less
prone to cause vibration than four-cylinder ones
(second inertia, etc.). However, any engine has many
moving parts in addition to its pistons and cannot be
completely free from vibration.
The four cylinder engine is fitted with balance weight
on crankcase to absorb the second inertia mentioned
above and reduce vibration.

3. LUBRICATING SYSTEM
[1] OIL COOLER
V3 series engine has a water-cooled oil cooler that
keeps the oil against overheat and also warms it up just
after the engine gets started.
As shown in the figure, the oil flows inside the
connected cooler plate, whereas coolant is kept
circulating outside the cooler plate, thereby cooling
down the oil.

4. COOLING SYSTEM
[1] THERMOSTAT
Conventional thermostatically-controlled valves
(outlet water temperature control type) open against the
flow of coolant. In this design, the pressure (steam
pressure + water pump's discharge pressure) affects
the open/close performance of such valve. In other
words, the valve may be delayed in opening at a preset
opening temperature get open suddenly at above the
preset temperature. This is called the overshoot
phenomenon.
The overshoot problem invites the undershoot
phenomenon too. Too much water cooled by the
radiator flows through the water passage, which
suddenly closes the valve at below the thermostat's
preset valve closing temperature.
A repeated cycle of such overshoot and undershoot
phenomena is called the water temperature hunting.
This hunting problem adversely affects not just the
cooling system parts but also the engine and its related
components.
To cope with this trouble, the V3 series engine is
equipped with the flow control thermostat. The valve
has a notch to control the coolant flowrate smoothly in
small steps.

[2] BOTTOM BYPASS SYSTEM

Bottom bypass system is introduced in V3 Series for
improving the cooling performance of the radiator.
While the temperature of coolant in the engine is low,
the thermostat is held closed and the coolant is allowed
to flow through the bypass pipe and to circulate in the
engine.
When the temperature exceeds the thermostat valve
opening level, the thermostat fully opens itself to
prevent the hot coolant from flowing through the bypass
into the engine.
In this way, the radiator can increase its cooling
performance.

5. FUEL SYSTEM
[1] GOVERNOR
The engine employs the separated fuel injection
pump in combination with Kubota’s own small multi­
function mechanical governor, which enable more
dependability.
It also employs the torque limiting mechanism to
control the maximum peak torque so that it complies
with the regulations of exhaust gas.
This mechanism maintains engine speed at a
constant level even under fluctuating loads, provides
stable idling and regulates maximum engine speed by
controlling the fuel injection rate.
This engine uses a mechanical governor that controls
the fuel injection rate at all speed ranges (from idling to
maximum speed) by utilizing the balance between the
flyweight's centrifugal force and spring tension.
A governor shaft for monitoring engine speed is
independent of the injection pump shaft and rotates at
twice the speed of conventional types, providing better
response to load fluctuation and delivering greater
engine output.
3EEAAAA1P064B
0000004846E
■ At Start
The stop solenoid (energized-to-run type) is powered
to release the stop lever.
As no centrifugal force is applied to flyweight (1), low
tension of start spring (2) permits control rack to move
the starting position, supplying the amount of fuel
required to start the engine.

B At Idling
Turn the speed control lever (3) clockwise to idle the
engine. It tensions the governor spring (4) to pull the
fork lever 2 (5).
When the fork lever 2 is pulled, it moves the torque
spring pin (6) and the fork lever 1 (7) in the direction of
the arrow A to restrain the weight. In combination with
the start spring tension, it is balanced with the
centrifugal force of flywheel weight to keep idling.

■ At rated speed with full load and overload

As the speed control lever is changed from the middle
speed to high speed, the governor spring tension
increases to compress the torque spring and move the
fork lever 1 in the direction of the arrow A.
The fork lever 2 moves until it reaches the output
limiting bolt to keep rated rotation and rated output.
When the engine is overloaded, the engine rotating
speed decreases and the centrifugal force of flywheel
weight decreases. Then the torque spring moves the
fork lever 1 in the direction of arrow A.
The control rack moves in the direction that increases
fuel supply to increase the output. It is balanced with the
centrifugal force of the flywheel weight to produce low-
speed output (torque output).

■ To stop engine
When the stop solenoid is turned off, the spring
tension of the solenoid is released, the rod extrudes and
the stop lever moves the control rack in the direction of
the arrow B which stops the engine.
To stop the engine manually, move the external stop
lever to the left.

6. TURBOCHARGER SYSTEM
[1] BOOST COMPENSATOR
The boost compensator is controlled by the boost
pressure of the turbocharger, which reduces transient
smoke caused by oversupply of fuel when the engine
starts and accelerates.
When the boost pressure is lower than working
pressure of the boost actuator (1), it prevents
oversupply of fuel to reduce transient smoke.
When the boost pressure is higher than working
pressure of the boost actuator (1), it controls the supply
of fuel to the equivalent of maximum power ! rated
speed output.
The boost compensator adjusting screws (2) are set
and tamper-proof capped in factory, so never take off
the tamper-proof cap and readjust the screws.

• Never remove the battery cap while the engine is running.
• Keep electrolyte away from eyes, hands and clothes. If you are spattered with it, wash it away
completely with water immediately.
• Keep open sparks and flames away from the battery at all times. Hydrogen gas mixed with oxygen
becomes very explosive.
■ IMPORTANT
• If the machine is to be operated for a short time without battery (using a slave battery for starting), use
additional current (lights) while engine is running and insulate terminal of battery. If this advice is
disregarded, damage to alternator and regulator may result.
• Insulate terminal of battery. If this advice is disregarded, damage to alternator and regulator may result.

Battery Specific Gravity

1. Check the specific gravity of the electrolyte in each cell with a
hydrometer.
2. When the electrolyte temperature differs from that at which the
hydrometer was calibrated, correct the specific gravity reading
following the formula mentioned in (Reference).
3. If the specific gravity is less than 1.215 (after it is corrected for
temperature), charge or replace the battery.
4. If the specific gravity differs between any two cells by more
than 0.05, replace the battery.
■ NOTE
• Hold the hydrometer tube vertical without removing it
from the electrolyte.
• Do not suck too much electrolyte into the tube.
• Allow the float to move freely and hold the hydrometer at
eye level.
• The hydrometer reading must be taken at the highest
electrolyte level.

(Reference)
• Specific gravity slightly varies with temperature. To be exact,
the specific gravity decreases by 0.0007 with an increase of
1 °C (0.0004 with an increase of 1 °F) in temperature, and
increases by 0.0007 with a decreases of 1 °C (0.0004 with a
decrease of 1 °F).
Therefore, using 20 °C (68 °F) as a reference, the specific
gravity reading must be corrected by the following formula :
-Specific gravity at 20 °C = Measured value + 0.0007 x
(electrolyte temperature - 20 °C)
-Specific gravity at 68 °F = Measured value + 0.0004 x
