BASE GP-OIL FILTER 3429849 - Caterpillar

3054 and 3056 Industrial Engines and Generator Set Engines are designed for the following applications: agricultural, industrial mobile equipment, generator set and auxiliary. The engines are available in the following types of aspiration:
Turbocharged aftercooled
Turbocharged
Naturally aspiratedAll emissions certified engines are equipped with an air/fuel ratio control that is located on the governor. The air/fuel ratio control restricts the fuel rack movement. Only the proper amount of fuel is allowed to be injected into the cylinders during acceleration. This fuel injection minimizes exhaust smoke.Emissions certified engines are equipped with a protection cover group that discourages tampering with the setting for the air/fuel ratio control. Standard bolts have been replaced by tamperproof bolts. This is required by regulations for emissions. Changing the air/fuel ratio control could cause the engine to exceed standards for emissions.The engines are powered with direct fuel injection. A hydramechanical governor controls the fuel injection pump output in order to maintain the engine rpm that is selected by the operator.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 rpm.The cooling system consists of the following components:
A centrifugal pump that is driven by a gear
One water temperature regulator which regulates the engine coolant temperature
An oil cooler
A radiator which incorporates a shunt systemThe engine lubricating oil is supplied by a gear type pump. The engine lubricating oil is cooled and the engine lubricating oil is filtered. 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 number 1 cylinder is the front cylinder.3054 Industrial Engines and Generator Set Engines
