Caterpillar original Caterpillar 295050-2400 common rail fuel injector replacement for OEM diesel engine spare parts new injector original new injector

The OEM Caterpillar 433-6862 / 4336862 fuel injector, cross-referenced with Denso 295050-2400 / 2950502400, is engineered as a direct replacement for CAT C4.4 and C7.1 diesel engines. Built to original equipment manufacturer specifications, this common rail injector delivers precise fuel metering, stable solenoid response, and reliable performance across demanding industrial applications including excavators, wheel loaders, backhoes, generator sets, and marine auxiliary engines.

Manufactured with precision-machined nozzles and a high-pressure tolerant design, the injector ensures superior fuel atomization and optimal combustion efficiency. Corrosion and wear-resistant materials extend service life, while factory calibration supports consistent injection parameters. Operators benefit from reduced fuel consumption, lower exhaust emissions, stable idle operation, and smoother throttle response across the full operating range of C4.4 ACERT and C7.1 Industrial Series engines.

For reliable operation, regular maintenance is recommended: replace fuel filters at scheduled intervals, use quality ultra-low-sulfur diesel, keep the fuel tank free of contaminants, and perform routine ECU diagnostics. Typical fault indicators include stored DTC fault codes, abnormal exhaust smoke color, and changes in engine noise. This replacement injector provides a dependable solution for heavy machinery, agricultural equipment, generator sets, and marine power units requiring OEM-level performance.
