SAFETY INSTRUCTIONS

SAFETY STARTING

• Do not start the engine by shorting across starter
terminals or bypassing the safety start switch.

• Do not alter or remove any part of machine safety
system.

• Before starting the engine, make sure that all shift
levers are in neutral positions or in disengaged
positions.

• Never start the engine while standing on ground.
Start the engine only from operator’s seat.

SAFETY WORKING

• Do not work on the machine while under the influe nce
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 work under the machine that is supported
solely by a jack. Always support the machine by
safety stands.

• 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.

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.

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.

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 regula tions when disp osing
of oil, fuel, coolant, electrolyte and other harmful
waste.

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.

G GENERAL

[ex.: Model Name V3300-E2]

The emission controls that have be en 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 E2 as a new model name for the
engines conforming Tier 2 / Phase 2 regulations with emissio n label
(1) or (2).

In the after-sale services for V3300-E2, V3300-TE2 and V3300­TIE2 series engines, only use the dedicated parts for E2 models a nd
carry out the maintenance services accordingly.

3. GENERAL PRECAUTIONS

• During disassembly, carefully arrange removed parts in a clean
area to prevent confusion later. Screws, bolts and nuts should b e
installed 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 provide d.

• Before disassembling or servicing electrical wires, always
disconnect the ground cable from the battery first.

• Remove oil and dirt from parts before measuring.

• Use only KUBOTA genuine parts for parts replacement to
maintain machine performance and to assure safety.

• Gaskets and O-rings must be replaced during reassembly.
Apply grease to new O-rings or oil seals before assembling.
See the figure left side.

• When reassembling external snap rings or internal snap rings,
they must be positioned so that sharp edge faces against the
direction from which a force is applied. See the figure left side.

• When inserting spring pins, their splits must face the direction
from which a force is applied. See the figure left side.

• To prevent damage to the hydraulic syst em, use only specified
fluid or equivalent.

NOTEQ

• Engine Oil : Oil used in the engine should have an Americ an Petroleum Institute (API) service classif ication
and Proper SAE Engine Oil according to the ambient temperature as shown above.
Do not mix different brands together.

• 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 t he CF-4 or CG­4 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.

• Transmission Oil : The oil used to lubricate the transmission is also used as hydraulic fluid. To insure
proper operation of the hydraulic system and complete lubrica tion of the transmission, it is important that
a multi-grade transmission fluid be used in t his system. We recommend the use of KUBOTA SUPER UDT
fluid for optimum protection and performance.
Do not mix different brands together.

Q Anti-Freeze

If coolant freezes, it can damage the cylinders and radiator. It is
necessary, if the ambient temp erature falls below 0 °C (32 °F), to
remove coolant after operating or to add anti-freeze to it.

1. There are two types of anti-freeze available ; use the permanent

type (PT) for this engine.

2. Before adding anti-freeze for the first time, clean the radiator

interior by pouring fresh water and draining it a few times.

3. The procedure for mixing of water and anti-freeze differs

according to the make of the anti-freeze and the ambient

temperature, basically is should be referred to SAE J1034

standard, more specifically also to SAE J814c.

4. Mix the anti-freeze with water, and then fill in to the radiator.

Freeze Point Boiling Point*

°C °F °C °F

*At 760 mmHg pressure (atmospheric). A high er boiling points is
obtained by using a radiator pressure cap which permits the
development of pressure within the cooling system.

NOTEQ

• The above data represent industry standards that
necessitate a minimum glycol content in the concentrated
anti-freeze.

• When the coolant level drops due to evaporation, add water
only. In case of leakage, add anti-freeze and 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 anti­corrosive agent, which will react with the radiator cleaning
agent forming sludge which will affect the engine parts.)

CAUTION

• Do not attempt mount a tire. This should be done by a qualified person with the proper equipment.
IMPORTANTQ

• Do not use tires larger than specified.

• When you intend to mount different size of tires from equipped ones, consult your distributor about front
drive gear ratio for detail.

• Excessive wear of tires may occur due to improper gear ratio.

Through the tire pressure is fa ctor y-set to the prescribed level, it
naturally drops slowly in the course of time. Thus, check it every day
and inflate as necessary.

To inflate the wheel tires, use an air compressor or hand pump.

[5] TIRE LIQUID INJECTION

Auxiliary weights can be used to increase traction force for plowing in fields or clayey ground.

Another way is to inject water or another liquid, such as a calcium chloride solution in the tires. Water must not be
used in winter since it freezes at 0 °C (32 °F). The calcium chloride solution will not freeze and moreover, affords
higher effect than water since its spec ific gr a v ity is hi gh e r than that of water by about 20 %. Below is an explanation
of calcium chloride solution injection.

IMPORTANTQ

• Do not fill the front tires with liquid.
Preparation of Calcium Chloride Solution

CAUTION

• When making a calcium chloride solution, do not pour water
over calcium chloride since this results in chemical reaction
which will cause high temperature. Instead add a small
amount of calcium chloride to the water at a time until the
desired solution is achieved.

Injection

CAUTION

• When a calcium chloride solution is used, cool it before
pouring it into the tire.

• Do not fill tires with water or solution more than 75 % of full
capacity (to the valve stem level).

The following four ways can be used to inject water or a calcium

chloride solution into tires.

1. Gravity injection (Fig. 1)

2. Pump injection (Fig. 2)

3. Pressure tank injection (Fig. 3)

4. Injection directly from tap (only when water is being used).

NOTEQ

• Once injection is completed, reset the air valve, and pump
air into the tire to the specified pressure.

3. Remove the air valve, and drain liquid (liquid can only be drained
to the level of the valve and liquid under that level remains
inside).

4. To drain liquid completely, use the injector (1), and direct
compressed air into the tire to force out the liquid through the
injector’s vent (3).

1. ENGINE BODY

[1] CYLINDER BLOCK

ENGINE

This engine employs separa te 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 /
disassemble it. The cylinder is a linerless type which
enables good cooling operation, less strain and good
abrasion resistance.

(2) Crankcase 2

(3) Oil Pan

W1012651

[2] CRANKSHAFT

This engine adopts the half counter system and
lightweight moving elements, and optimizes the oil
clearance of bearings to reduce noise and vibration.

It also adopts a large diameter journal to improve
rigidity and reliability, and enable large capacity P.T.O.
(Power take-off).

to 2062 psi) of the injection nozzle (5) is injected into the combustion chamber.

Part of the fuel fed to the injection nozzle (5) lubricates the moving parts of the plunger inside the nozzle, then
returns to the fuel tank (1) through the overflow pipe (7) and check valve (8) another end of overflow pipe is connected
to pump body by joint.

Thus, this system is designed to prevent mixing of air into fu el whic h ca us es ha rd sta rtin g .

[1] FUEL FILTER

The fuel filter is installed between the fuel tank and
fuel lift pump, and serves to remove dirt and impurities
from the fuel.

Fuel from the fuel tank enters the outside of the filter
element (2) and passes through the filter element under
its own pressure. As it passes through, the dirt and
impurities in the fuel are filtered out, allowing only clean
fuel to enter the interior of the filter element.

The feed pump (1) sends fuel from the fuel tank to the
injection pump by applying pressure to fuel.
