Chapter 1 .Introduction
This tractor service manual is for qualified service personnel engaged in servicing
and overhauling 3510/4110/T390(T400)/T430(T450) tractor.Use of this publication
is not recommended for field operators since they usually do not have access to
special tools and shop equipment essential for most servicing.
Servicing procedures outlined herein contain sufficient information to return all
component parts of a tractor to new condition. In discussion of each component
parts,it is assumed that a complete overhaul is been performed,consequently,
complete disassembly and reassembly are outlined.The mechanic is relied upon to
decide how far disassembly must be carried when complete overhaul is not required.
Study unfamiliar service procedures thoroughly and clearly understood before
attempting disassembly. Specific data essential for proper overhaul,such as running
clearances and torque values,have been provided in interline of Inspection and
reassembly procedures of each group section.
This manual was compiled from latest information available at time of publication.
Manufacturer reserves the right to make changes at any time without notice.
Whenever the terms "left"and "right" are used, They means as viewed by the
operator when seated in the operator's seat.

SAFETY INSTRUCTION
ALWAYS PRACTICE SAFETY BY THINKING BEFORE ACTION
AVOID FIRE HAZARDS.
-Keep fire extinguishers easily available and in good operating condition.
All relevant personnel should know how to operate fire fighting equipment.
-Keep a first aid kit in an easily accessible location.
-Do not smoke while handling fuel,or other highly flammable material.
-Do not use an open pail for transporting fuel.
-Use of an approved fuel container.
-Dispose of all fuel-soaked rags in covered containers where cigarettes cannot be dropped
carelessly.
-Do not smoke and avoid open flame when charging,jumping,or boosting batteries.
-Batteries give off gas which is flammable and explosive.
-Do not charge batteries in a closed area. Provide proper ventilation to avoid explosion of
accumulated gases.
Avoid acid burns.
-Wear safety goggles when handling battery electrolyte.It contains sulfuric acid which is a
poison and can cause blindness.Avoid it contacting eyes,skin,or clothing. sulfuric acid will eat
through clothing and can cause severe burns to skin.
AVOID HIGH-PRESSURE FLUIDS
1) Before beginning work on hydraulic system components,turn off engine and operate
hydraulic control levers to relieve internal hydraulic pressure.
2) Oil under pressure can penetrate skin and lead to personal injury.Treat sources of oil
pressure with extreme care,wearing safety goggles.
3) If hydraulic leak develops,correct immediately.Escaping hydraulic oil can have extremely
high pressure. A stream of high pressure oil may easily penetrate skin just like modern needless
vaccination equipment,but with the exception that hydraulic fluid may cause blood poisoning.
It is imperative that connections are tight and that all lines and pipes should be in good condition.
If injured by escaping hydraulic fluid,see a doctor at once.
1-2
STAY CLEAR OF PTO
1) Entanglement in rotating drive line can cause serious injury or death.
2) Keep tractor master shield and drive line shield in place at all times except for special
applications as directed in the implement operator's manual.
3) Wear fairly tight tight fitting clothing.Stop the engine and be sure PTO driveline is stopped
before making adjustment,connections,or cleaning out PTO drive equipment.
SERVICE TIRES SAFELY
Tire changing can be dangerous and should be done by trained personnel using proper tools and
equipment.
Do not re-inflate a tire that has been run flat or seriously under-inflated.Have it checked by qualified
personnel.
Use wheel handling equipment adequate for weight involved when removing and installing wheels.

USE OF ROPS AND SEAT BELT
The Roll Over Protective Structure(ROPS) has been certified to
industry and/or government standards. Any damage or alternation to
the ROPS, mounting hard-ware, or seat belt voids the certification
and will reduce or eliminate protection for the operator in the event
of a roll-over. The ROPS, mounting hardware, and seat belt should
be checked after the first 100 hours of Tractor and every 500 hours
thereafter for any evidence of damage, wear or cracks. In the event
of damage or alteration, the ROPS must be replaced prior to further
operation of the Tractor.
The seat belt must be worn during machine operation when the
machine is equipped with a certified ROPS.
Failure to do so will reduce or eliminate protection for the operator
in the event of a roll over.
PRECAUTION TO AVOID TIPPING
Do not drive where the Tractor could slip or tip.
Stay alert for holes and rocks in the terrain, and other hidden
hazards.
Slow down before you make a sharp turn.
Driving forward out of a ditch or mired condition could cause
Tractor to tip over backward. Back out of these situations if
possible
PARK TRACTOR SAFELY

Keep the surrounding area of the Tractor clean and dry.
Do not attempt to service Tractor when it is in motion.
Keep body and clothing away from rotating shafts.
Always lower equipment to the ground. Stop the engine.
Remove the key. Allow Tractor to cool before any work repair is
caused on it.
Securely support any Tractor elements that must be raised for service
work.
Keep all parts in good condition and properly installed.
Replace worn or broken parts. Replace damage/missing decals.
Remove any buildup of grease or oil from the Tractor.
Disconnect battery ground cable(−) before making adjustments on
electrical systems or welding on Tractor
1-8
AVOID HIGH-PRESSURE FLUIDS
Escaping fluid under pressure can penetrate the skin causing
serious injury. Keep hands and body away from pinholes and
nozzles, which eject fluids under high pressure. If ANY fluid is
injected into the skin. Consult your doctor immediately.
PREVENT BATTERY EXPLOSIONS
Keep sparks, lighted matches, and open flame away from the
top of battery. Battery gas can explode.
Never check battery charge by placing a metal object across the
poles.
PREVENT ACID BURNS
Sulfuric acid in battery electrolyte is poisonous. It is strong enough to
burn skin, cause holes in clothing and cause blindness if found entry
into eyes.
For adequate safety always;
1. Fill batteries in a well-ventilated area.
2. Wear eye protection and acid proof hand gloves
3. Avoid breathing direct fumes when electrolyte is added.
4. Do not add water to electrolyte as it may splash off
causing severe burns.
If you spill acid on yourself;
1.Flush your skin with water.
2.Flush your eyes with water for 10-15 minutes.
Get medical attention immediately.
SERVICE TRACTOR SAFELY
Do not wear a necktie, scarf or loose clothing when you work near
moving parts. If these items were to get caught, severe injury could
result.
Remove rings and other jeweler to prevent electrical shorts and
entanglement in moving parts.
WORK IN VENTILATED AREA
Do not start the Tractor in an enclosed building unless the doors &
windows are open for proper ventilation, as tractor fumes can cause
sickness or death. If it is necessary to run an engine in an enclosed area
remove the exhaust fumes by connecting exhaust pipe extension.
