Required Maintenance and Warranty Information
Information in This Section Does Not Apply Outside the United States of AmericaForeword
The United States Environmental Protection Agency has issued regulations to establish emission standards and ensure that new motor vehicle engines will perform within prescribed limits. These regulations require new motor vehicle and new motor vehicle engine manufacturers to furnish maintenance instructions necessary to ensure the proper functioning of the engine within these limits. This publication has been prepared for this purpose.MAINTENANCE, REPLACEMENT, OR REPAIR OF THE EMISSION CONTROL DEVICES AND SYSTEMS MAY BE PERFORMED BY ANY AUTOMOTIVE REPAIR ESTABLISHMENT OR INDIVIDUAL USING ANY AUTOMOTIVE PART WHICH HAS BEEN CERTIFIED PURSUANT TO EPA REGULATIONS.Authorized dealers are recommended for major maintenance and repair work as they are staffed with trained servicemen, necessary tools and are aware of the latest service methods and procedures. Owners and others who desire to perform their own work should purchase a Service Manual and obtain current information from their Caterpillar dealer.Emission Control
The combustion process of a diesel engine produces exhaust products such as smoke (visible), hydrocarbons and oxides of nitrogen (invisible). The dark smoke emitted by a diesel engine is soot or carbon particles and even in low concentration makes the diesel exhaust highly visible and offensive to most people. Every effort must be made to eliminate smoke through proper maintenance and operation.Under certain conditions oxides of nitrogen react with certain hydrocarbons to form smog which can become irritating and toxic if large concentrations accumulate. Concentrations of this pollutant combined with pollution of other sources all contribute to the total air quality problem.As an engine manufacturer, our goal is to see that environmental standards are met with a minimum additional complexity or cost to the product. Throughout the years, continuing research and design improvements have been directed at minimizing exhaust emissions. Caterpillar has incorporated items such as -TURBOCHARGING: Reduces exhaust noise and provides more air per cylinder allowing the fuel to burn more efficiently. These engines are integrally designed for turbocharging.FUEL-AIR RATIO CONTROL FOR TURBOCHARGED ENGINES: Limits the amount of fuel during acceleration to minimize smoke levels.RECOMMEND FUELS, LUBRICATING OILS AND MAINTENANCE SCHEDULES: To assure minimum exhaust emissions.Maintenance Recommendations
Caterpillar Truck Engines are certified by the United States Environmental Protection Agency to comply with smoke and gaseous emission standards prescribed by Federal laws at the time of manufacture.Efficiency of emission control and good engine performance depend on adherence to proper operation and maintenance recommendations, use of recommended fuels and lubricating oils. It is recommended that major adjustments and repair be entrusted to your authorized dealer.Various chemical fuel additives are commercially available that claim to reduce visible smoke. Although additives have been used by individuals to solve some isolated smoke problems in the field, they are not recommended for general use. Federal smoke regulations require the certification of engines without a smoke depressant.The corrective steps taken immediately on discovery of worn parts, which may affect emission levels, will help assure proper operation of emission control systems.
