COUPLING GP-FLEXIBLE 1838212 - Caterpillar

Correct operation and maintenance are key factors in obtaining the maximum life and economy of the engine. If the directions in the Operation and Maintenance Manual are followed, costs can be minimized and engine service life can be maximized.The engine can be operated at the rated rpm after the engine reaches operating temperature. The engine will reach normal operating temperature sooner during a low engine speed (rpm) and during a low-power demand. This procedure is more effective than idling the engine at no load. The engine should reach operating temperature in a few minutes.Gauge readings should be observed and the data should be recorded frequently while the engine is operating. Comparing the data over time will help to determine normal readings for each gauge. Comparing data over time will also help detect abnormal operating developments. Significant changes in the readings should be investigated.Minimum Engine Run Time
Changes to the operating cycle may be required when the engines are applied in a manner that will result in repeated occurrences of less than one hour of continuous run time.In order for the exhaust aftertreatment to function properly, the engine must complete a DPF regeneration to 0 percent soot load once in every 24 hours of engine run time.After this regeneration to 0 percent soot has finished, an additional 70 minutes of run time is needed for Cat Regeneration System fuel nozzle maintenance. Both of these requirements can be run with or without load on the engine.Engines rated for constant speed use are allowed to complete a starting sequence, an operation at a single constant speed, and a shutdown sequence. Every time the engine is run, each of these operations should occur only once. The starting sequence and shutdown sequence can include a short period of operation at the low idle speed for purposes of warming up and cooling down the engine or driven equipment. The emissions type approval is not valid for operation of a constant speed engine in a manner different from that described above.
