LINES GP-CIRCLE DRIVE MOTOR 2G3460 - Caterpillar

marine operator is concerned with performance, cost of operation and satisfactory engine life. Traditionally, poor performance of the vessel is believed to result from a lack of engine performance or from a loss of engine performance. In fact, the engine is only one of numerous factors that influence the overall performance of a vessel.Several factors determine the power demand on an engine. The engine does not have control over the demand that is caused by the vessel design. The vessel design includes the following features:
Hull
Propeller
Drive trainThe design of the hull, the propeller, and the drive train also affect the amount of power that is available to perform additional work. For example, those features affect the power that is used to drive an auxiliary pump.If a problem with the performance of the vessel occurs, consider the following effects on power demand:
Loads
Condition of the vessel
Vessel design
Condition of the drive train
Condition of the propellerDeterioration of the engine systems decreases the ability of the engine to produce power and vessel speed. Engine systems include the cooling system, the lubrication system, the fuel system, etc. The engine is not likely to be the cause of poor fuel economy without excessive exhaust smoke and/or the loss of power.If you have a valid problem with the engine performance, consult an authorized Cat dealer for assistance.If the engine is covered by a warranty, the Caterpillar warranty covers the cost of solving a valid deficiency of the engine performance. However, if the engine is not at fault, all costs that are incurred will be the responsibility of the owner.Note: Adjustment of the fuel system outside Caterpillar specified limits will not improve fuel efficiency. Adjustment of the fuel system outside Caterpillar specified limits could also result in damage to the engine.Cat engines are manufactured with state-of-the-art technology. Cat engines are designed to help provide two characteristics in all applications:
Maximum performance
Fuel efficiencyTo ensure optimum performance for the service life of the engine, follow the recommended operation procedures that are described in this manual. Also, follow the preventive maintenance procedures that are described in this manual.Performance Analysis Report (PAR)
To verify the condition of the propulsion system, Caterpillar has developed the Performance Analysis Report (PAR) for marine engines.A PAR is an in-vessel test procedure that is performed by a Cat analyst under operating conditions. The test compares the performance of all marine engine systems to the original testing specifications.When a PAR is conducted at Sea Trial, an installation of high quality can be ensured. The PAR will confirm the matching of the following components for optimum performance and for fuel efficiency: hull, rudders, propeller, marine transmission, ventilation and cooling systems.Caterpillar recommends scheduling a PAR in order to maintain optimum performance.A periodic PAR can define deterioration of the propulsion system. A PAR can assist in repairs, in overhauls, and in maintenance schedules. A PAR will help to provide the most economical, efficient cost of operation.
