Chapter 1 .Introduction
This tractor service manual is for qualified service personnel engaged in servicing
and overhauling 2810/T290/T300/T330 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

Disassembly and reassembly of major components
SECTION 1. GENERAL PRECAUTIONS FOR SEPARATION AND REINSTALLATION
2. PRECAUTIONS TO BE FOLLOWED
WHEN INSTALLING STANDARDIZED
PARTS.
(1) Roller or Ball bearings
1) When a bearing is fitted in by the
outer race,use an installer which
is an specially designed to push
only the outer race and vice versa.
2) The installer must be designed to
install the bearing on the shaft in
a parallel position.
3) When installing a bearing which
appears the same on both sides,
install it so that the face which
has the identification number faces
in a direction for easy visual
identification.All the bearings
which are to be installed in the
transmission case should be
placed so that their identification
number faces outward.
4) If a shaft or hole where a bearing
is to be installed has a stopper,
the bearing should be pushed in
completely until it is seated against
the stopper.
5) Installed bearings should turn
smoothly.
(2) Oil seals
1) Oil seals installer should be
designed so as not to deform the oil
seals.
1.BEFORE OPERATION
1) Always be safety-conscious in selecting
clothes to wear and suitable tools to use.
2) Before disassembly, be sure that you
familiarize yourself with the assembled
condition for subsequence in reassembly.
3) Keep parts and tools in proper order
