Maintenance Recommendations
Some Caterpillar marine diesel engines are certified by the United States Environmental Protection Agency (EPA) to comply with gaseous and particulate emission standards that are prescribed by Federal laws at the time of manufacture.The engine is certified if it has a special certification label. Two types of labels that are used by Caterpillar are shown above. A Caterpillar dealer can also inform you if the engine is certified and to which category the engine is certified.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. It is recommended that major adjustments and repairs should be performed by your authorized Caterpillar dealer.The corrective steps taken immediately on discovery worn parts, which may affect emission levels, will help assure 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.UNIT INJECTORS - Unit injectors are subject to tip 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 unit injector should be inspected, tested and replaced, if necessary. Unit injectors can be tested by an authorized Caterpillar marine engine dealer.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" (Maintenance Section).ELECTRONIC ENGINE CONTROL - This component is a device that is designed to control engine operation with respect to the amount of fuel injected, the injection timing as well as controlling the black smoke emission of an engine during the engine's operation when low inlet manifold pressure exists. Any erratic engine behavior may indicate a need for adjustment or repair. Your Caterpillar dealer is equipped with the necessary tools, personnel and procedures in order to perform this service.The owner is encouraged to keep adequate maintenance records. However, the absence of such records will not invalidate the warranty. Refer to the Operation and Maintenance Manual, "Maintenance Log" (Reference Materials Section).The vehicle owner may perform routine maintenance, repairs and
