original 169-7408 Fuel Injector for 3408 3412 Diesel Engine Excavator Parts Replacement for OEM 174-7527 222-5967 20R-0760 156-3895 original new injector

Engineered as a direct OEM-equivalent replacement, the 169-7408 diesel fuel injector delivers precise, high-pressure fuel atomization for the . 3412 engine family, including 3412B, 3412C, and 3412E variants. Manufactured from high-strength alloy steel and 100% flow tested prior to shipment, this injector assembly (cross-referenced as 1697408 and CAT1697408) ensures dimensional compatibility with original components and reliable performance under continuous heavy-duty operation.

Designed for demanding industrial environments, this fuel injector serves marine propulsion systems, generator sets, mining trucks, oilfield drilling rigs, industrial compressors, and construction power units. Global applications include cargo vessels, fishing boats, tugboats, emergency power systems, prime power stations, data center backup generators, drilling equipment, crushing plants, pumping units, and compressor stations. Precision nozzle technology and flow-matched calibration improve combustion efficiency, reduce fuel consumption, increase horsepower output, lower exhaust emissions, and extend overall engine service life, while corrosion-resistant construction supports long operational lifespan in harsh conditions.

Recommended maintenance includes daily inspection for fuel leakage, exhaust smoke monitoring, and pressure stability checks; injector condition and fuel filter inspection every 500 hours; and bench testing, spray pattern verification, and opening pressure measurement every 2,000 hours. Common diagnostics: black smoke indicates atomization issues, white smoke signals injector leakage, hard starts suggest fuel pressure problems, power loss points to restricted flow, and engine knock reflects timing or spray pattern faults. Supplied new with a 12-month warranty.
