TORQUE CONVERTER 9S1060 - Caterpillar

Maintenance Recommendations
Caterpillar Inc. truck engines are certified by the United States Environmental Protection Agency (EPA) and the California Air Resources Board in order to comply with exhaust emission standards and gaseous emission standards that are prescribed by law at the time of manufacture.Efficiency of the emission control and the engine performance depends on adherence to proper operation and maintenance recommendations and use of recommended fuels and lubricating oils. According to recommendations, major adjustments and repairs should be made by your authorized Caterpillar dealer.Various chemical fuel additives which claim to reduce visible smoke are available commercially. Although additives have been used to solve some isolated smoke problems in the field, additives are not recommended for general use. The engines should be certified without smoke depressants according to federal smoke regulations.Take corrective steps immediately after worn parts which may affect emission levels are discovered in order to ensure the proper operation of the emission control systems. The use of genuine Caterpillar parts is recommended. Suppliers of non-Caterpillar parts must ensure the owner that the use of such parts will not adversely affect emission levels.Regular maintenance intervals with a special emphasis on the following items are necessary in order to keep exhaust emissions within acceptable limits for the useful life of the engine. Refer to the Operation and Maintenance Manual, "Severe Service Application - Check" topic (Maintenance Section). If the engine is operating under severe conditions, adjust the maintenance schedule accordingly. See your authorized Caterpillar dealer in order to help analyze your specific application, operating environment and maintenance schedule adjustments.The following information is an explanation of maintenance items for emission related components. See the Operation and Maintenance Manual, "Maintenance Interval Schedule" (Maintenance Section) for the specific interval for the following items.EXHAUST AFTERTREATMENT SYSTEM - Aftertreatment systems are sensitive to the type of fuel and lubricants used and the operating schedule. Poor quality fuel, lubricants or fluids may cause increases in exhaust backpressure or clogging resulting in loss of power. An authorized Caterpillar truck engine dealer can determine if the aftertreatment system needs service.CLEAN GAS INDUCTION (CGI) - A maintenance indicator light monitors the CGI system. An authorized Caterpillar truck engine dealer can determine if the CGI system needs service.FUEL INJECTORS - Fuel injector tips are subject to wear as a result of fuel contamination. This damage can cause the following conditions: an increase in fuel consumption, black smoke, misfire and rough running engine. The fuel injector should be inspected, tested and replaced, if necessary. Fuel injectors can be tested by an authorized Caterpillar truck engine dealer.Additionally, a maintenance indicator light indirectly monitors the fuel injector tip component of the Aftertreatment Regeneration Device (ARD). An authorized Caterpillar truck engine dealer can determine if the ARDsystem needs service.TURBOCHARGER - Check for any unusual sound or vibration in the turbocharger. Inspect the inlet piping and connections and inspect the exhaust piping and connections. Check the condition of the bearing. Perform the maintenance that is described in the Operation and Maintenance Manual, "Maintenance Interval Schedule"
