TO THE READER

This Workshop Manual has been prepared to provide servicing personnel with

information on the mechanism, service and maintenance of KUBOTA Tractors M6800,

M6800S, M8200 and M9000. It is divided into two parts, “Mechanism” and “Servicing”

for each section except “ENGINE” section.

Q Mechanism

Information on the constructuion and function are included. This part should be

understood before proceeding with troubleshooting, disassembling and servicing.

Q Servicing

Under the heading “General” section comes general precautions, check and

maintenance and special tools. Other section, there are troubleshooting, servicing

specification lists, checking and adjusting, disassembling and assembling, and servicing

which cover procedures, precautions, factory specifications and allowable limits.

All information illustrations and specifications contained in this manual are based on

the latest product information available at the time of publication.

The right is reserved to make changes in all information at any time without notice.

SAFETY INSTRUCTIONS

BEFORE SERVICING AND REPAIRING

• Read all instructions and safety instructions in this

manual and on your machine safety decals.

• Clean the work area and machine.

• Park the machine on a firm and level ground, and set

the parking brake.

• Lower the implement to the ground.

• Stop the engine, and remove the key.

• Disconnect the battery negative cable.

• Hang a “DO NOT OPERATE” tag in operator

station.

SAFETY FIRST

This symbol, the industry’s “Safety Alert Symbol”, is used throughout this manual and on labels on

the machine itself to warn of the possibility of personal injury. Read these instructions carefully.

It is essential that you read the instructions and safety regulations before you attempt to repair or use

this unit.

DANGER : Indicates an imminently hazardous situation which, if not avoided, will result in

death or serious injury.

WARNING : Indicates a potentially hazardous situation which, if not avoided, could result in

death or serious injury.

CAUTION : Indicates a potentially hazardous situation which, if not avoided, may result in

minor or moderate injury.

Q IMPORTANT : Indicates that equipment or property damage could result if instructions are not

followed.

Q NOTE : Gives helpful information.

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 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 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 regulations when disposing

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.

Engine Serial Number

The engine serial number is an identified number for the engine.

It is marked after the engine model number.

It indicates month and year of manufacture as follows.

• Year of manufacture

• Month of manufacture

e.g. V3300-YA0001

“Y” indicates 2000 and “A” indicates January.

So, YA indicates that the engine was manufactured on January,

2000.

[2] E2 ENGINE

[ex.: Model Name V3300-E2]

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 E2 as a new model name for the

engines conforming Tier 2 / Phase 2 regulations with emission label

(1) or (2).

In the after-sale services for V3300-E2, V3300-TE2 and V3300-

TIE2 series engines, only use the dedicated parts for E2 models and

carry out the maintenance services accordingly.

W1113734

[3] CYLINDER NUMBER

The cylinder numbers of V3300-E2, V3300-TE2 and V3300-TIE2

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.
