Avoid AccidentsMost accidents, whether they occur in the air, inindustry, on the farm, at home, on the highways, orat sea, are caused by someone's failure to followsimple and fundamental safety rules or precautions. For this reason most accidents can be prevented by recognizing the real cause and doingsomething about it before the accident occurs.Regardless of the care used in the design andconstruction of any type of equipment, there aremany conditions that cannot be completely safeguarded against without interfering with reasonable accessibility and efficient operation.A careful operator is the best insurance againstan accident.The complete observance 01 one simple rulewould prevent many thousands 01 serious injurieseach year. That rule is: "Never attempt to clean.oil or adjust a machine while it is in motion."T24352

ForewordCaterpillar products are a result of advancedengineering, skilled manufacturing, and the finestmaterials metallurgical science can select. Thousands of satisfying, economical working hours arebuilt into each machine.Whether or not the owner derives the maximumservice from his machine depends largely on thecare exercised in its operation and maintenance.This book is written to give the operator essentialinformation regarding the day-to-day operation,lubrication and adjustment of the machine. Careful adherence to these instructions will result inassured economy.More and more Caterpillar owners are depending upon their dealer for service other than thecare and adjustments described in this book.This practice is recommended because Caterpillardealers have stocks of genuine Caterpillar partsand are equipped with tools designed and builtby Caterpillar. Their servicemen are factorytrained and are kept closely informed by the factory regarding advanced methods of servicingCaterpillar products - thus, in all ways they areequipped to render the best of service.T20841

5Lubrication Instructions SERVICE METERThe Service Meter is located on the right side of the engine near thebottom of the governor housing. It is geared to the engine, and whenthe crankshaft turns as many revolutions as are made in an hour ataverage operating speeds on an average job application, the dial advances one number. There are some applications that will result in eithera lower or higher than normal average engine speed. Under this condition, the advance in the Service Meter reading will differ fromthe numberof clockhours of operation.The purpose of the Service Meter is to indicate when to perform therecommended maintenance and lubrication operations. The establishedintervals in the lubrication chart and maintenance instructions are givenin service hours, so daily readings will tell when to service the tractor.Rely on the Service Meter and not on the clock to measure serviceintervals.SERVICE METER GENERAL LUBRICATING INFORMATIONNaturally, any precautions taken during cold weather to house thetractor, cover it with a tarpaulin, or warm it before starting, will causemore rapid oil distribution.Lubricate all miscellaneous points, not equipped with fittings, withcrankcase lubricating oil every 50service hours.It is extremely important in handling the oil to keep it clean. Everyprecaution should be taken to use only clean filler cans and to be surethat all dirt is removed from the filler cap before it is taken off for filling.The operator should take every precaution to prevent dirt from gettinginto any system to extend the life of the tractor.

6LUBRICATION INSTRUCTIONSCareful attention to the following information on lubricants and theirproper selection will add much to performance, economy and long lifeof your tractor. The lubrication chart specifies the lubricants to be used,the points to be serviced and the intervals of servicing according toservice hours.DESCRIPTION OF LUBRICANTSThe lubricants recommended for use in this tractor can be identifiedby the sub-heading preceding their descriptions that follow. The properselection of one of these types of crankcase lubricating oils, and SAEgrade of oils can be made from the information in the topic, TYPEOFLUBRICANTSAND SAE GRADESTO USE.Crankcase Lubricating OilsSuperior Lubricants (Series 3): These are additive-type oils that havebeen identified as meeting a rigid, high quality standard and certifiedfor use in all Caterpillar Diesel Engines. See your Caterpillar dealer forbrand names of products conformingto this specification.MIL-L-2104A Specification Oils: These oils are additive-type but aremilder than Superior Lubricants (Series 3) Oils. They can be used asspecified for various compartments satisfactorily. Your oil supplier isfamiliar with those oils meeting the MIL-L-2104ASpecification.Straight Mineral Crankcase Lubricating Oil: Most of these oils willcontain a very small concentration of engine oil additives. Oils without additives can be used in certain compartments as specified.Lubricating GreaseBall and Roller Bearing Lubricant: This lubricant is a mixture of mineral oil and metallic soaps. Use No.2 grade for most temperatures. For extremely low temperatures use No. 0 or No. I grade.This grease can be applied to all bearing points - plain bearings,ball bearings and roller bearings - where equipped with hydraulicpressure fittingsor when bearings are hand packed.Use only a high grade short fiber grease. This grease must be satisfactory in anti-friction bearings at speeds up to 3000RPMat a maximumtemperature of 300 F. It is a grease with sufficient adhesive qualities tocling to the bearings in all extremes of high and low operating temperatures.

LUBRICATION7AINSTRUCTIONS7BThe oil specification chart will aid in the proper oil grade selection forthe various compartments. The proper SAE grade of oil to select is determined by the atmospheric temperature at which the machine is started.However, during operation SAE lOW oil can be used successfully inthe diesel engine crankcase when atmospheric temperatures are as highas 70 F.Crankcase Lubricating Oil Change PeriodsThe crankcase lubricating oil change periods for these engines havebeen carefully established for the purpose of protecting the service lifeof the engine as economicallyas possible.Change the oil and filter elements after the first 10 service hours ofoperation of a reconditioned engine.DIESEL ENGINE CRANKCASE LUBRICATING OIL CHANGE PERIOD CHARTUse Only Superior Lubricants (Series 3)FUEL SULPHUR CONTENTOIL CHANGE PERIOD"FILTER ELEMENTCHANGE PERIOD"0.4 o or less250 Service Hrs.250 Service Hrs.0.4% to 1.0%125 Service Hrs.""250 Service Hrs."Regardless of time operated, the crankcase oil and filter elements should bechanged at least every six months.""Reduce crankcase oil change periods one half when sulphur content is greaterthan 1.0 o.LUBRICATION CHARTCATERPILLARD7 TRACTORThe illustration on the following page indicates theapproximate locations of all points requiring servicing.The chart is keyed to this illustration and to the relateddetailed topics and illustrations on the succeeding pages.The service intervals are mesaured in service meter hours.
