SAFETY PRECAUTIONS

Practically all service work involves the need to drivethe tractor. The operators manual, supplied witheach tractor, contains detailed safety precautionsrelating to driving, operating, and servicing thattractor. These precautions are as applicable to theservice technician as they are to the operator andshould be read, understood and practiced by allpersonnel.

Prior to undertaking any maintenance, repair,overhaul, dismantling or reassembly operations,whether within a workshop facility or in the field,consideration should be given to factors that mayhave an effect upon safety, not only upon themechanic carrying out the work, but also uponbystanders.

PERSONAL CONSIDERATIONSThe wrong clothes or carelessness in dress cancause accidents. Check to see that you are suitableclothed.

Some jobs require special protective equipment.

Skin ProtectionUsed motor oil may cause skin cancer. Follow workpractices that minimize the amount of skin exposedand length of time used oil stays on your skin.

Eye ProtectionThe smallest eye injury may cause loss of vision.Injury can be avoided by wearing eye protectionwhen engaged in chiselling, grinding, discing,welding, and painting.

Breathing ProtectionFumes, dust, and paint spray are unpleasant andharmful. These can be avoided by wearingrespiratory protection.

Hearing ProtectionLoud noise may damage your hearing, and thegreater the exposure the worse the damage. If thenoise is excessive, wear ear protection.

Lifting ProtectionAvoid injury by correctly handling components. Makesure you are capable of lifting the object. If in doubtget help.

Hand ProtectionIt is advisable to use a protective cream before workto prevent irritation and skin contamination. Afterwork clean your hands with soap and water. Solventssuch as mineral spirit and kerosene may harm theskin.

Foot ProtectionSubstantial or protective footwear with reinforced toecaps will protect your feet from falling objects.Additionally, oil-resistant soles will help to avoidslipping.

Special ClothingFor certain work it may be necessary to wear flameor acid-resistant clothing.

EQUIPMENT CONSIDERATIONS

Machine GuardsBefore using any machine, check to ensure that themachine guards are in position and serviceable.These guards not only prevent parts of the body orclothing coming in contact with the moving parts ofthe machine, but also ward off objects that might flyoff the machine and cause injury.

Lifting DevicesAlways ensure that lifting equipment, such as chains,slings, lifting brackets, hooks and eyes, arethoroughly checked before use. If in doubt, selectstronger equipment than is necessary.

Never stand under a suspended load or raisedimplement.

Compressed AirThe pressure from a compressed-air line oftenexceeds 690 bar (100 PSI). It is perfectly safe if usedcorrectly. Any misuse may cause injury.

Never use compressed air to blow dust, filing, and dirtaway from your work area unless the correct type ofnozzle is fitted.

Compressed air is not a cleaning agent; it will onlymove dust from one place to another. Look aroundbefore using an air hose as bystanders may get gritinto their eyes, ears, or skin.


00-5

Hand ToolsMany cuts, abrasions and injuries are caused bydefective tools. Never use the wrong tool for the job,as this generally leads either to some injury or to apoor job.

When removing or replacing hardened pins, use acopper or brass drift rather than a hammer.

For dismantling, overhaul, and assembly of majorand sub-components, always use the SpecialService Tools recommended. These will reduce thework effort, labor time, and the repair cost.

ElectricityElectricity has become so familiar in day to dayusage, that its potentially dangerous properties areoften overlooked. Misuse of electrical equipment canendanger life.

Before using any electrical equipment - particularlyportable appliances - make a visual check to makesure that the wiring is not worn or frayed and that theplugs and sockets are intact. Make sure you knowwhere the nearest isolating switch for yourequipment is located.

GENERAL CONSIDERATIONS

SolventsUse cleaning fluids and solvents that are known to besafe. Certain types of fluids can cause damage tocomponents, such as seals, and can cause skinirritation. Solvents should be checked that they aresuitable not only for the cleaning of components andindividual parts, but also that they do not affect thepersonal safety of the user.

HousekeepingMany injuries result from tripping over or slipping onobjects or material left lying around by a carelessworker. Prevent these accidents from occurring. Ifyou notice a hazard, dont ignore it - remove it.

A clean, hazard-free place of work improves thesurroundings and daily environment for everybody.

FireFire has no respect for persons or property. Thedestruction that a fire can cause is not always fullyrealized. Everyone must be constantly on guard.

Extinguish matches, cigars, and cigarettes beforethrowing them away.

Work cleanly, disposing of waste material into propercontainers.

Locate the fire extinguishers and find out how tooperate them.

Do not panic - warn those near and raise the alarm.

Do not allow or use an open flame near the tractorfuel tank, battery, or component parts.

First AidIn the type of work that mechanics are engaged in,dirt, grease, and fine dusts settle upon the skin andclothing. If a cut, abrasion or burn is disregarded itmay become infected within a short time. Seekmedical aid immediately.

CleanlinessCleanliness of the tractor hydraulic system isessential for optimum performance. When carryingout service and repairs, plug all hose ends andcomponent connections to prevent dirt entry.

Clean the exterior of all components before carryingout any form of repair. Dirt and abrasive dust canreduce the efficiency and working life of a componentand lead to costly replacement. Use of ahigh-pressure washer or steam cleaner is recom-mended.

OPERATIONAL CONSIDERATIONSStop the engine, if at all possible, before performingany service.

Place a warning sign on tractors which, due toservice or overhaul, would be dangerous to start.Disconnect the battery leads if leaving such a unitunattended.

Do not attempt to start the engine while standingbeside the tractor or attempt to bypass the safetystart switch.

Avoid prolonged running of the engine in a closedbuilding or in an area with inadequate ventilation asexhaust fumes are highly toxic.

Always turn the radiator cap to the first stop to allowpressure in the system to dissipate when the coolantis hot.

Never work beneath a tractor which is on soft ground.Always take the unit to an area which has a hardworking surface, preferably concrete.


00-6

If it is found necessary to raise the tractor for ease ofservicing or repair, make sure that safe and stablesupports are installed beneath axle housings,casings, etc., before starting work.

Certain repair or overhaul procedures may necessi-tate separating the tractor, either at the engine/trans-mission or transmission/rear axle location. Theseoperations are simplified by the use of the TractorSplitting Stands. Should this equipment not beavailable, every consideration must be given tostability, balance and weight of the components,especially if a cab is installed.

Use footsteps or working platforms when servicingthose areas of a tractor that are not within easy reach.

Before loosening any hoses or tubes connectingimplements to remote control valves, etc., switch offthe engine, remove all pressure in the lines byoperating levers several times. This will remove thedanger of personal injury by oil pressure.

Prior to pressure testing, make sure all hoses andconnectors of the tractor and the test equipment arein good condition and tightly sealed. Pressurereadings must be taken with the gauges specified.The correct procedure should be rigidly observed toprevent damage to the system or the equipment, andto eliminate the possibility of personal injury.

WARNINGEscaping hydraulic/diesel fluid under pressurecan penetrate the skin causing serious injury.Do not use your hand to check for leaks. Use apiece of cardboard or paper to search for leaks.Stop the engine and relieve pressure beforeconnecting or disconnecting lines.Tighten all connections before starting theengine or pressurizing lines.If any fluid is injected into the skin, obtainmedical attention immediately or gangrene mayresult.

Use position control when equipment or imple-ments are required to be attached to the hydrauliclinkage either for testing purposes or for transporta-tion.

Always lower equipment to the ground when leavingthe tractor.

If high lift attachments are installed on a tractor,beware of overhead power, electric or telephonecables when traveling. Drop the attachment near toground level to increase stability and minimize risks.

Do not park or attempt to service a tractor on anincline. If unavoidable, take extra care and block allwheels.

Observe recommended precautions as indicated inthis Service Manual when dismantling the air-conditioning system as escaping refrigerant cancause frostbite.

Prior to removing wheels and tires from a tractor,check to determine whether additional ballast (liquidor weights) has been added. Seek assistance anduse suitable equipment to support the weight of thewheel assembly.

When inflating tires, beware of over inflation -constantly check the pressure. Overinflation cancause tires to burst and result in personal injury.

HEALTH AND SAFETY PRECAUTIONS

Many of the procedures associated with vehiclemaintenance and repair involve physical hazards orother risks to health. This section lists, alphabetically,some of these hazardous operations, materials andequipment associated with them. The precautionsnecessary to avoid these hazards are identified.

The list is not inclusive; all operations, procedures,and handling of materials should be carried out withhealth and safety in mind.

ACIDS AND ALKALIS (See Battery Acids,i.e., Caustic Soda, Sulfuric Acid)Used in batteries and cleaning materials.

Irritating and corrosive to the skin, eyes, nose andthroat. Causes burns.

Avoid splashes to the skin, eyes, and clothing. Wearsuitable protective gloves and goggles. Can destroyordinary protective clothing. Do not breathe mists.

Ensure access to water and soap is readily availablefor splashing accidents.

ADHESIVES AND SEALERS (See Fire)

CAUTIONHIGHLY FLAMMABLE, COMBUSTIBLE.

Generally should be stored in NO SMOKING areas;cleanliness and tidiness while in use should beobserved, i.e., from applications where possible,disposable paper should be dispensed to coverbenches. Containers, including secondary contain-ers, should be labeled.

Solvent-Based Adhesives/Sealers (SeeSolvents)Follow manufacturers Instructions

Water-Based Adhesives/SealersThose based on polymer emulsions and rubberlattices may contain small amounts of volatile toxicand harmful chemicals.

Skin and eye contact should be avoided, andadequate ventilation provided during use.

Follow manufacturers Instructions

Resin-Based Adhesive/Sealers (i.e., Epoxideand Formaldehyde Resin Based)Mixing should only be carried out in well- ventilatedareas as harmful or toxic volatile chemicals may bereleased.

Skin contact with uncured resins and hardeners canresult in irritation, dermatitis, and absorption of toxic,or harmful chemicals through the skin. Splashes candamage the eyes.

Provide adequate ventilation; avoid skin and eyecontact. Follow manufacturers instructions.

Anaerobic, Cyanoacrylate and other AcrylicAdhesivesMany are irritating, sensitizing, or harmful to the skin.Some are eye irritants.

Skin and eye contact should be avoided and themanufacturers instructions followed.

Cyanoacrylate adhesives (super-glues) must notcontact the skin or eyes. If skin or eye tissue isbonded, cover with a clean moist pad and getmedical attention. Do not attempt to pull tissue apart.Use in well-ventilated areas as vapors can causeirritation of the nose and eyes.

For two-part systems: See Resin-Based Adhesive/Sealers

Isocyanate (Polyurethane) Adhesive/Sealers(See Resin-Based Adhesives)Individuals suffering from asthma or respiratoryallergies should not work with, or near, thesematerials as sensitivity reactions can occur.

Any spraying should preferably be carried out inexhaust ventilated booths removing vapors andspray droplets from the breathing zone. Individualsworking with spray applications should wearsupplied air respirators.

ANTIFREEZE (See Fire, Solvents, i.e.,Isopropanol, Ethylene Glycol, Methanol)


Used in vehicle coolant systems, brake air pressuresystems, and windshield washing solutions.


00-8

Vapors given off from coolant antifreeze (Glycol)arise only when heated.

Antifreeze may be absorbed through the skin in toxicor harmful quantities. Swallowed antifreeze is fatal ifnot treated; medical attention must be soughtimmediately.

BATTERY ACIDS (See Acids and Alkalis)Gases released during charging are explosive.Never use an open flame or allow sparks nearcharging or recently charged batteries.

BRAKE AND CLUTCH LININGS AND PADS(See Legal Aspects)These items may contain asbestos which, if inhaled,may cause lung damage and, in some cases, cancer.

The normal handling and fitting of these items shouldnot cause any hazard, but any drilling, grinding, orfilling of friction materials may produce asbestos dustand should only be carried out under strictlycontrolled conditions.

The dust in brake drums, etc., contains very littleasbestos, but care should be taken to avoidinhalation of this dust during servicing of brakes andclutches. The use of drum cleaning units, vacuumcleaning, or damp wiping is preferred to the use of airjets for blowing-out.

The dust should be collected in a sealed plastic bagand disposed appropriately, according to local lawsand regulations.

BRAZING (See Welding)

CHEMICAL MATERIALS - GENERAL (SeeLegal Aspects)Chemical materials such as solvents, sealers,adhesives, paints, resin foams, battery acids,antifreeze, oils, and grease should always be usedwith caution, stored and handled with care. They maybe toxic, harmful, corrosive, irritating, or highlyflammable, causing hazardous fumes and dusts.

The effects of excessive exposure to chemicals maybe immediate or delayed, briefly experienced orpermanent, cumulative, superficial, life threatening,or may reduce life expectancy.

CLUTCH LININGS AND PADS (See Brakeand Clutch Linings and Pads)

CORROSION PROTECTION MATERIALS(See Solvents, Fire)


These materials are varied; the manufacturersinstructions should be followed. They may containsolvents, resins, and petroleum products. Skin andeye contact should be avoided. They should only besprayed in conditions of adequate ventilation, andnot in confined spaces.

CUTTING (See Welding)

DEWAXING (See Solvents and Fuels -Kerosene)

DOSDo remove chemical materials from the skin andclothing as soon as practicable. Change heavilysoiled clothing and have it cleaned.

Do carefully read and observe hazard andprecaution warnings given on material containers(labels) and in any accompanying leaflets, poster orother instructions. Material health and safety datasheets can be obtained from manufacturers.

Do organize work practices by wearing protectiveclothing and safety devices to avoid contact withchemical materials; breathing vapors, aerosols,dusts, and fumes; inadequate container labeling; orfire and explosion hazards.

Do wash before job breaks, before eating, smoking,drinking, or using toilet facilities when handlingchemical materials.

Do keep work areas clean, uncluttered, and free ofspills.

Do store according to national and local regulations.

Do keep chemical materials out of reach of children.

DONTSDo not mix chemical materials except under themanufacturers instructions; some chemicals canform other toxic or harmful chemicals, releasing toxicor harmful fumes, or be explosive when mixedtogether.

Do not spray chemical materials, particularly thosebased on solvents, in confined spaces, i.e., whenpeople are inside a vehicle.


00-9

Do not apply heat or flame to chemical materials,except under the manufacturers instructions. Someare highly flammable, and some may release toxic orharmful fumes.

Do not leave containers open. Escaping fumes canbuild up to toxic, harmful, or explosive concentra-tions. Some fumes are heavier than air and willaccumulate in confined areas, pits, etc.

Do not transfer chemical materials to unlabeledcontainers.

Do not clean hands or clothing with chemicalmaterials. Chemicals, particularly solvents and fuels,will dry the skin, and may cause irritation withdermatitis. Some can be absorbed through the skinin toxic or harmful quantities.

Do not use emptied containers for other materials,except when they have been cleaned undersupervised conditions.

Do not sniff or smell chemical materials. Briefexposure to high concentrations of fumes can beharmful or toxic.

DUSTSPowder or dusts may be an irritant, harmful or toxic.Avoid breathing dusts from powdery chemicalmaterials, or those arising from dry abrasionoperations. Wear respiratory protection if ventilationis inadequate.

ELECTRIC SHOCKElectric shocks can result from the use of faultyelectrical equipment or from the misuse of equipmenteven in good condition.

Ensure electrical equipment is maintained in goodcondition and frequently tested.

Ensure flexes, cables, plugs and sockets are notfrayed, kinked, cut, cracked, or otherwise damaged.

Ensure electric equipment is protected by the correctrated fuse.

Never use electrical equipment or any otherequipment which is in any way faulty. The resultscould be fatal.

Use reduced voltage equipment for inspection andworking lights, where possible.

Ensure the cables of mobile electrical equipmentcannot get trapped and damaged, such as in avehicle hoist.

In Cases of Electrocution:

Switch off electricity before approaching victim.

If this is not possible, push or drag the victim fromthe source of electricity using dry non-conductivematerial.

Commence resuscitation if trained to do so.

SUMMON MEDICAL ASSISTANCEIMMEDIATELY

EXHAUST FUMESThese contain asphyxiating, harmful and toxicchemicals, and particles such as carbon oxides,nitrogen oxides, aldehydes, lead, and aromatichydrocarbons. Engines should only run underconditions of adequate extraction, or generalventilation, not in confined spaces.

Diesel EngineSoot, discomfort, and irritation usually give adequatewarning signs of hazardous fume concentration.

FIBER INSULATION (See Dusts)Used in noise and sound insulation.

The fibrous nature of surfaces and cut edge cancause skin irritation. This is usually a physical, not achemical effect.

Precautions should be taken to avoid excessive skincontact through careful organization of workpractices and the use of gloves.

FIRE (See Welding, Foams, Legal Aspects)Many of the materials found on, or associated with,the repair of vehicles are highly flammable. Somerelease toxic or harmful fumes if burned.

Observe strict fire safety when storing and handlingflammable materials or solvents, particularly nearelectrical equipment or welding processes.

Before using electrical or welding equipment, be surethere is no fire hazard present.

Have a suitable fire extinguisher available whenusing welding or heating equipment.


00-10

FIRST AIDApart from meeting any legal requirements, it isdesirable for someone in the workshop to be trainedin first aid procedures.

Splashes in the eye should be flushed with cleanwater for at least ten minutes.

Soiled skin should be washed with soap and water.

Inhalation affected individuals should be removed tofresh air immediately.

If chemicals are swallowed, consult a doctorimmediately with (label) information on materialused.

Do not induce vomiting, unless indicated bymanufacturer.

FOAMS - POLYURETHANE (See Fire)Used in sound and noise insulation. Cured foams areused in seat and trim cushioning.

Follow manufacturers instructions.

Unreacted components are irritating and may beharmful to the skin and eyes. Wear gloves andgoggles.

Individuals with chronic respiratory diseases,asthma, bronchial medical problems, or histories ofallergic diseases should not work with or nearuncured materials.

The components vapors and spray mists can causedirect irritation and/or sensitivity reactions and maybe toxic or harmful.

Vapors and spray mists must not be breathed. Thesematerials must be applied with adequate ventilationand respiratory protection. Do not remove respiratorimmediately after spraying, wait until vapor/mistshave cleared.

Burning of the uncured components and the curedfoams can generate toxic and harmful fumes.

Smoking, open flames, or the use of electricalequipment should not be allowed during foamingoperations until vapors/mists have completelycleared. Any heat cutting of cured foams or partiallycured foams should be conducted with extractionventilation (see Legal Aspects).

FUELS (See Fire, Legal Aspects,Chemicals - General, Solvents)Used as fuels and cleaning agents.

Gasoline (Petrol)


Swallowing can result in mouth and throat irritation;absorption from the stomach can result indrowsiness and unconsciousness. Small amountscan be fatal to children. Aspiration of liquid into thelungs, i.e., through vomiting, is a very serious hazard.

Prolonged or repeated contact with gasoline driesthe skin and causes irritation and/or dermatitis.Liquid in the eye causes severe pain.

Motor gasoline may contain high quantities ofbenzene which is toxic upon inhalation; theconcentrations of gasoline vapors must be kept verylow. High concentrations will cause eye, nose andthroat irritation, nausea, headache, depression andsymptoms of drunkenness. Very high concentra-tions will result in rapid loss of consciousness.

Ensure there is adequate ventilation when handlingand using gasoline. Great care must be taken toavoid the serious consequences of inhalation in theevent of vapor buildup arising from spillages inconfined spaces.

Special precautions apply to cleaning and mainte-nance operations on gasoline storage tanks.

Gasoline should not be used as a cleaning agent. Itmust not be siphoned by mouth.

Kerosene (Paraffin)Used also as heating fuel, solvent, and cleaningagent.

CAUTIONFLAMMABLE

Irritation of the mouth and throat may result fromswallowing. The main hazard from swallowing arisesif liquid aspiration into the lungs occurs. Liquidcontact dries the skin and can cause irritation and/ordermatitis. Splashes in the eye may be slightlyirritating.

In normal circumstances, the low volatility does notgive rise to harmful vapors. Exposure to mists andvapors from kerosene at elevated temperaturesshould be avoided (mists may arise in dewaxing).Avoid skin and eye contact; be sure there is adequateventilation.


00-11

Diesel Fuel (Gas-Oil) (See Fuels -Kerosene)

CAUTIONCOMBUSTIBLE

Gross or prolonged skin contact with high boiling gasoils may cause serious skin disorders, including skincancer.

GAS CYLINDERS (See Fire)Gases such as oxygen, acetylene, carbon dioxide,argon, and propane are normally stored in cylindersat pressures of up to 137.8 bar (2000 PSI). Greatcare should be taken in handling these cylinders toavoid mechanical damage to them or the valve gearattached. The contents of each cylinder should beclearly identified by appropriate markings.

Cylinders should be stored in well-ventilatedenclosures and protected from ice, snow, or directsunlight. Fuel gases, i.e., acetylene and propane,should not be stored in close proximity to oxygencylinders.

Care should be exercised to prevent leaks from gascylinders and lines and to avoid sources of ignition.

Only trained personnel should undertake workinvolving gas cylinders.

GASES (See Gas Cylinder)

GAS SHIELDING WELDING (See Welding)

GAS WELDING (See Welding)

GENERAL WORKSHOP TOOLS ANDEQUIPMENTIt is essential that all tools and equipment aremaintained in good condition and the correct safetyequipment used where required.

Never use tools or equipment for any purpose otherthan for which they were designed.

Never overload equipment such as hoists, jacks,axle and chassis stands, or lifting slings. Damagecaused by overloading is not always immediatelyapparent and may result in a fatal failure the next timethe equipment is used.

Do not use damaged, defective tools or equipment,particularly high-speed equipment such as grindingwheels. A damaged grinding wheel can disintegratewithout warning causing serious injury.

Wear suitable eye protection when using grinding,chiseling, or sandblasting equipment.

Wear a suitable breathing mask when usingsandblasting equipment, working with asbestosbased materials, or using spraying equipment.

GLUES (See Adhesive and Sealers)

HIGH-PRESSURE AIR, LUBRICATION ANDOIL TEST EQUIPMENT(See Lubricants and Greases)Always keep high-pressure equipment in goodcondition and regularly maintained, particularly jointand unions.

Never direct a high-pressure nozzle at the skin, asthe fluid may penetrate to the underlying tissue andcan cause serious injury.

LEGAL ASPECTSMany laws and regulations make requirementsrelating to health and safety in the use of materialsand equipment in workshops.

Workshops should be familiar, in detail, with theselaws and regulations.

LUBRICANTS AND GREASESAvoid all prolonged and repeated contact withmineral oils, especially used oils. Gross andprolonged skin contact with used oils contaminatedduring service, i.e., routine service change sump oils,are more irritating and more likely to cause seriouseffects, including skin cancer.

Wash skin thoroughly after work involving oil.Proprietary hand cleaners may be of value providedthey can be removed from the skin with water. Do notuse petrol, paraffin, or other solvents to remove oilfrom the skin.

Lubricants and greases may be slightly irritating tothe eyes.

Repeated or prolonged skin contact should beavoided by wearing protective clothing, if necessary.Particular care should be taken with used oils andgreases containing lead. Do not allow work clothingto be contaminated with oil. Dry clean or laundersuch clothing at regular intervals. Discard oil-soakedshoes.

Do not use previously used engine oils as lubricantsor for any application where major skin contact islikely to occur. Used oils may only be disposed of inaccordance with local regulations.


00-12

NOISE INSULATION MATERIAL (SeeFoams, Fiber Insulation)

PAINTS (See Solvents and ChemicalMaterials - General)

CAUTIONHIGHLY FLAMMABLE

Paints can contain harmful or toxic pigments, driers,and other components, as well as solvents. Sprayingshould only be carried out with adequate ventilation.

Two-part or catalyzed paints can also containharmful and toxic unreacted resins and resin-hard-ening agents. The manufacturers instructionsshould be followed and the section on resin-basedadhesives, isocyanate containing adhesive andfoams should be consulted.

Spraying should preferably be carried out inexhausted ventilated booths, removing vapor andspray mists from the breathing zone. Individualsworking in booths should wear respiratory protection.Those doing small-scale repair work in the openshop should wear supplied air respirators.

PAINT THINNERS (See Solvents)

PRESSURIZED EQUIPMENT (See High-Pressure Air, Lubrication and Oil TestEquipment)

RESISTANCE WELDING (See Welding)

SEALERS (See Adhesives and Sealers)

SOLDER (See Welding)Solders are mixtures of metals in which the meltingpoint of the mixture is below that of constituent metals(normally lead and tin). Solder application does notnormally give rise to toxic lead fumes, provided agas/air flame is used. Oxyacetylene flames shouldnot be used, as they are much hotter and will causelead fumes to be released.

Some fumes may be produced by the application ofany flame to surfaces coated with grease, etc., andinhalation of these should be avoided.

Removal of excess solder should be undertaken withcare to ensure fine lead dust is not produced, whichcan cause toxic effects if inhaled. Respiratoryprotection may be necessary.

Solder spillage and filing should be collected andremoved promptly to prevent general air contamina-tion by lead.

High standards of personal hygiene are necessary inorder to avoid ingestion of lead or inhalation of solderdust from clothing.

SOLVENTS (See Chemical Materials -General, Fuels [Kerosene], Fire)Acetone, White spirit, Toluene, Xylene, Trichlore-thane.

Used in cleaning materials, dewaxing, paints,plastics, resins, thinners, etc.

CAUTIONHIGHLY FLAMMABLE

Skin contact will degrease the skin and may result inirritation and/or dermatitis following repeated orprolonged contact. Some can be absorbed throughthe skin in toxic or harmful quantities.

Splashes in the eye may cause severe irritation andcould lead to loss of vision.

Brief exposure to high concentrations of vapors ormists will cause eye and throat irritation, drowsiness,dizziness, headaches and, in the worst circum-stances, unconsciousness.

Repeated or prolonged exposures to excessive, butlower concentrations of vapors or mists, for whichthere might not be adequate warning indications, cancause more serious toxic or harmful effects.Aspiration into the lungs, i.e., through vomiting, is themost serious consequence.

Avoid splashes to the skin, eyes, and clothing. Wearprotective gloves, goggles, and clothing if necessary.

Ensure good ventilation when in use, avoid breathingfumes, vapors, and spray mists. Keep containerstightly sealed. Do not use in confined spaces.

When the spraying material contains solvents, e.g.,paints, adhesives, and coatings, use extractionventilation or personal respiratory protection in theabsence of adequate general ventilation.

Do not apply heat or flame, except under specific anddetailed manufacturers instructions.


00-13

SOUND INSULATION (See Fiber Insulation,Foams)

SPOT WELDING (See Welding)

SUSPENDED LOADSThere is always a danger when loads are lifted orsuspended. Never work under an unsupported,suspended, or raised load, e.g., jacked-up vehicle,suspended engine, etc.

Always ensure lifting equipment such as jacks,hoists, axle stands, slings, etc., are adequate andsuitable for the job, in good condition, and regularlymaintained.

Never improvise lifting tackle.

UNDER SEAL (See Corrosion Protection)

WELDING (See Fire, Electric Shock, GasCylinders)Welding processes include Resistance Welding(Spot Welding), Arc Welding, and Gas Welding.

Resistance WeldingThis process may cause particles of molten metal tobe emitted at high velocity; the eyes and skin must beprotected.

Arc WeldingThis process emits a high level of ultraviolet radiationwhich may cause eye and skin burns to the welderand to other persons nearby. Gas-shielded weldingprocesses are particularly hazardous in this respect.Personal protection must be worn and screens usedto shield other people.

Metal spatter will also occur; appropriate eye andskin protection is necessary.

The heat of the welding arc will produce fumes andgases from the metals being welded and from any

applied coatings or contamination of the surfacesbeing worked on. These gases and fumes may betoxic; inhalation should always be avoided. The useof extraction ventilation to remove the fumes from theworking area may be necessary, particularly in caseswhere the general ventilation is poor, or whereconsiderable welding work is anticipated. In extremecases where adequate ventilation cannot beprovided, supplied air respirators may be necessary.

Gas WeldingOxyacetylene torches may be used for welding andcutting; special care must be taken to preventleakage of these gases, subsequently reducing therisk of fire and explosion.

The process will produce metal spatter; eye and skinprotection is necessary.

The flame is bright and eye protection should beused, but the ultraviolet emission is much less thanthat from arc welding, and lighter filters may be used.

The process itself produces few toxic fumes, butsuch fumes and gases may be produced fromcoatings on the work, particularly during cutting awayof damaged parts. Inhalation of the fumes should beavoided.

In brazing, toxic fumes may be released from themetals in the brazing rod. A severe hazard may ariseif brazing rods containing cadmium are used. In thisevent, particular care must be taken to avoidinhalation of fumes; an experts advice may berequired.

SPECIAL PRECAUTIONS MUST BE TAKENBEFORE ANY WELDING OR CUTTING TAKESPLACE ON VESSELS WHICH HAVE CONTAINEDCOMBUSTIBLE MATERIALS, I.E., BOILING ORSTEAMING OUT THE INSIDE OF FUEL TANKS.

SERVICE TECHNIQUES

GENERALClean the exterior of all components before carryingout any form of repair. Dirt and abrasive dust canreduce the efficient working life of a component andlead to costly replacement.

Time spent on the preparation and cleanliness ofworking surfaces will pay dividends in making the jobeasier and safer and will result in overhauledcomponents being more reliable and efficient inoperation.

Use cleaning fluids which are known to be safe.Certain types of fluid can cause damage to O ringsand cause skin irritation. Solvents should be checkedthat they are suitable for the cleaning of componentsand also that they do not risk the personal safety ofthe user.

Replace O rings, seals or gaskets whenever they aredisturbed. Never mix new and old seals or O rings,regardless of condition. Always lubricate new sealsand O rings with hydraulic oil before installation.

When replacing component parts, use the correcttool for the job.

HOSES AND TUBESAlways replace hoses and tubes if the cone end orthe end connections on the hose are damaged.

When installing a new hose, loosely connect eachend and make sure the hose takes up the designedposition before tightening the connection. Clamps

should be tightened sufficiently to hold the hosewithout crushing and to prevent chafing.

After hose replacement to a moving component,check that the hose does not foul by moving thecomponent through the complete range of travel.

Be sure any hose which has been installed is notkinked or twisted.

Hose connections which are damaged, dented,crushed or leaking, restrict oil flow and theproductivity of the components being served.Connectors which show signs of movement from theoriginal swaged position have failed and willultimately separate completely.

A hose with a chafed outer cover will allow waterentry. Concealed corrosion of the wire reinforcementwill subsequently occur along the hose length withresultant hose failure.

Ballooning of the hose indicates an internal leakagedue to structural failure. This condition rapidlydeteriorates and total hose failure soon occurs.

Kinked, crushed, stretched or deformed hosesgenerally suffer internal structural damage which canresult in oil restriction, a reduction in the speed ofoperation and ultimate hose failure.

Free-moving, unsupported hoses must never beallowed to touch each other or related workingsurfaces. This causes chafing which reduces hoselife.


00-22

O RING FLAT FACE SEAL FITTINGSWhen repairing O ring face seal connectors, thefollowing procedures should be observed.

WARNINGNever disconnect or tighten a hose or tube thatis under pressure. If in doubt, actuate theoperating levers several times with the engineswitched off prior to disconnecting a hose ortube.

1. Release the fittings and separate the hose ortube assembly, then remove and discard the Oring seal from the fitting.

2. Dip a new O ring seal into clean hydraulic oil priorto installation. Install a new O ring into the fittingand, if necessary, retain in position usingpetroleum jelly.

3. Assemble the new hose or tube assembly andtighten the fitting finger tight, while holding thetube or hose assembly to prevent it from turning.

4. Use two suitable wrenches and tighten the fittingto the specified torque according to the size of thefitting. Refer to the following torque chart.

NOTE: To ensure a leak-free joint is obtained, it isimportant that the fittings are not over or undertorqued.

Supply TanksTwo fuel tanks are standard equipment. The lower, ormain, tank, 4, having a capacity of 246 L (65 U.S.gallons), is located along the left side of the centeraxle housing. The upper, or auxiliary, tank, 2, havinga capacity of 170 L (45 U.S. gallons), is located belowthe cab toward the rear of the tractor. Fuel tank filling,8, as well as the engine supply and return, areaccomplished through the lower tank. A large,diameter tube, 3, connects the upper and lowertanks. There is no valve on this tube, so it is notpossible to isolate the upper and lower tanks. Thetanks are vented through a tube attached to theupper tank. The vent tube, 1, extends up the right rearcab post. Both the supply, 6, and return fittings, 7, onthe lower tank contain shutoff valves to ease service.The supply fitting threads into a 24 mesh inlet screen,5, approximately 76 mm (3) long, which in turnthreads into the fuel tank. The return fitting containsa drain cock.

Fuel Filter/Water Separator/Primer PumpThe primary purpose of this assembly is to removewater and solid contaminants from the fuel before thefuel enters the gallery of the injection pump. Theplunger and barrel assemblies (pumping elements)of the injection pump are matched to each other withan accuracy of a few ten thousandths of an inch.Impurities of this size can cause severe damage, orexcessive wear, to the injection pump and injectorassemblies. The fuel filter assembly consists of amanifold, or base, containing the primer pump, 3,along with a bleed port. For the 70A Series tractor,the primer pump, 3, is now on the top of the supplypan. The primer and bleeder (70 Series only) areused when the engine has run out of fuel or a newfilter element has been installed. Threaded onto themanifold is the filter element. The water separator, 1,is in turn threaded onto the filter element. Theseparator bowl contains a drain, 2, that can be usedif water or sediment are observed.

The fuel injection pump, the heart of the fuel system,consists of a number of subassemblies.

70-150-2203

The supply pump is the entry point into the enginefuel system from the tanks. The supply pump ismechanically driven by the injection pump camshaft.The purpose of the supply pump is to draw fuel fromthe tank, and pressurize the fuel to a minimum of 1.4bar (20 PSI) in order to cause fuel to flow through thefilter, and to provide sufficient pressure for pumpingelement filling. The supply pump housing alsocontains a sedimenter assembly consisting of a clearbowl, 1, and strainer screen, 2. The clear bowl shouldbe inspected for sediment every 50 hours andcleaned every 300 hours.

70-150-152

The rear portion of the injection pump assemblyhouses the all-speed RSV mechanical governor.The governor receives inputs from the following:

Throttle control lever, 1

Intake manifold pressure, 3

Injection pump camshaft speed, 4

Engine oil pressure, 2

Mechanical fuel shutoff lever, engine side ofpump (not shown), which is, in turn, controlled bythe fuel shutoff solenoid

11. Full load stop (fuel delivery)12. Fulcrum lever13. Guide bushing14. Flyweight15. Swiveling lever16. Rocker17. Strap18. Control rod

Receiving these inputs, the governor, by moving thepumping element control rack, 18, controls engine-off, excess fuel for starting, minimum and maximumidle speeds, and any midrange speeds independentof load. A pair of flyweights, 14, are attached to thepump camshaft. The force of the flyweightsincreases with engine speed. The force of theweights operates against that of the governor spring,8. The tension on the governor spring is varied by the

position of the throttle lever, 3. Also contained withinthe governor housing is the starting spring, 2. Thislightweight spring pulls the fuel control rack fullyforward to the excess fuel position whenever theengine is not running. As soon as the engine startsand the flyweights begin to generate force, thestarting spring is overcome and the rack returns tonormal fuel delivery.


10-12

Aneroid assemblyThe aneroid assembly prevents excessive smokeunder load by limiting maximum fuel delivery until theturbocharger is providing sufficient air to effect cleancombustion. An example of this operation would bestarting a load out onto a roadway, when the engineis idling, and throttle position and load are increasedsimultaneously.

The aneroid also contains a hydraulic activator, 1,which is controlled by engine oil pressure, A. Whenthere is no oil pressure, B, the activator allows thecontrol rack full travel to the excess fuel position.Without this feature, during starting, fuel deliverywould be extremely limited due to lack ofturbocharger boost pressure.

Overflow Valve AssemblyThe supply pump has a capacity of about twice thatof the requirements of the high-pressure pumpingelements. This excess flow provides cooling andlubrication for the injection pump. Flow from thesupply pump travels through the filter element andthen to the fuel gallery of injection pump, where it isavailable to fill the pumping elements. The fuel mustbe pressurized in order to properly fill the pumpingelements. The job of the overflow valve, 1, is tomaintain a pressure of approximately 1.5 bar (22PSI) in the fuel gallery. Once that pressure isreached, the overflow valve opens and allows theexcess fuel to return to the tank.

70-150-2208

High-Pressure Pumping ElementsThe high-pressure pumping elements, one for eachengine cylinder, supply fuel at a pressure ofapproximately 240 bar (3500 PSI) to the injectors.The pumping elements must provide the fuel in aprecisely measured amount at the proper time.

Operation of the individual element is as follows:

Fuel Delivery CycleReference (A) -- Bottom dead center /

Fuel in

Reference (B) -- Spill port closure /Fuel Pressurized

Reference (C) -- Spill port opening /Fuel delivery ends

(A) With the plunger, 1, at the bottom of the stroke,fuel flows into the barrel through the spill port, 2,and fills the space above the plunger.

(B) As the plunger, 1, rises, the spill port in the barrel,3, is covered and the fuel is trapped. This is thepoint of port closure. The continued upwardmovement of the plunger pressurizes thetrapped fuel until the delivery valve (at the baseof each high-pressure injection line) is lifted fromits seat. High- pressure fuel is transmittedthrough the line to the injector and injection takesplace through the injector nozzle.

(C) Injection stops when the upper edge of the helix,4, uncovers the lower edge of the spill port.Pressure escapes to the fuel gallery. The drop inpressure causes the injector to close andinjection to stop. After fuel delivery ceases, theplunger continues to the top of the stroke and isreturned by a spring for the next cycle.

Because the end of delivery is reached when thehelix on the plunger uncovers the spill port, 1, theamount of fuel delivered is varied by turning thepump plunger as shown at D. If the plunger isturned until the vertical groove completelyuncovers the spill port as shown at E, during theentire lift of the plunger, there will be no fueldelivered to the engine. This is because injectionpressure cannot be reached, thereby shutting offthe engine.

The plungers are rotated by a control racksplined to each plunger. Rack movement isdetermined by the control rod, actuated by thegovernor.

Fuel Delivery and Timing During StartingThe plungers, 1, are equipped with starting grooves,2, on their crown. The purpose of this groove is toassist in starting the engine by providing both excessfuel and slightly retarded timing. When the key switchis turned on, the fuel shutoff solenoid retracts,moving the mechanical shutoff lever to the RUNposition. The starting spring in the governor housingpulls the control rack fully forward, beyond thenormal maximum fuel position. This aligns thestarting groove with the spill port. With the startinggroove aligned with the spill port, there is a delay inspill port closure which, in turn, delays the start ofinjection. Note also that there is no helix in this regionof the plunger, so once injection begins,
