KIT-GASKET 3496937 - Caterpillar

The 3034 Marine Engine is available as a turbocharged arrangement or as a naturally aspirated arrangement.The engine is powered by direct fuel injection. A mechanical governor controls the fuel injection pump output in order to maintain the engine speed that is selected by the operator. The engines are equipped with a protection cover group that discourages tampering.Fuel is metered and pumped by a fuel injection pump under high pressure to the fuel injection nozzles (one per cylinder). The automatic timing advance provides the best fuel injection timing over the full range of engine speed.The cooling system consists of the following components:
A centrifugal jacket water pump that is belt driven
One water temperature regulator which regulates the engine coolant temperature
Heat exchanger for the closed water circuit
Sea water pump
Strainer for the supply for the sea water
Expansion tankThe engine lubricating oil is supplied by a gear type pump. The engine lubricating oil is cooled and filtered on the turbocharged engine. The engine lubricating oil is filtered on the naturally aspirated engine. Bypass valves provide unrestricted flow of lubrication oil to the engine parts when oil viscosity is high. Bypass valves can also provide unrestricted flow of lubrication oil to the engine parts if the oil cooler should become plugged or if the oil filter element should become plugged.Engine efficiency, efficiency of emission controls, and engine performance depend on adherence to proper operation and maintenance recommendations. Engine performance and efficiency also depend on the use of recommended fuels, lubrication oils, and coolants. Refer to the Operation and Maintenance Manual, "Maintenance Interval Schedule" for more information on maintenance items.Engine Specifications
Note: The front end of the engine is opposite the flywheel end of the engine. The left and the right side of the engine are determined from the flywheel end. The No. 1 cylinder is the front cylinder. 3034 Marine Engine
