Caterpillar original 235-5261 Diesel Engine Fuel Injector 267-3360 for C9 Engine Replacement, compatible with 235-9649, 235-1401 for Construction Machinery Excavator Parts original new injector

Designed for Caterpillar C9 engine platforms, the 235-5261 fuel injector delivers precise, high-pressure diesel fuel delivery for construction equipment, mining machinery, industrial power units, marine propulsion systems, and generator sets. As an OEM-equivalent replacement, it cross-references Caterpillar numbers 2355261, 10R-7675, and 328-2574, giving fleet operators and parts distributors a reliable sourcing option for CAT C9, C9 ACERT, industrial, marine, and generator engine maintenance.

Within the Caterpillar fuel injection system, this injector functions as a high-precision metering device. The engine's electronic control module signals the needle valve to open, releasing exactly metered fuel through the nozzle holes, where it atomizes into microscopic particles for efficient combustion. The result is optimized fuel delivery timing, spray pattern, and atomization quality, translating into improved combustion efficiency, stronger horsepower output, lower fuel consumption, reduced exhaust emissions, sharper engine response, and stable idle performance under heavy-duty operating conditions.

Built to strict OEM specifications, the 235-5261 features a precision-machined, corrosion-resistant injector body with factory-calibrated performance and a heavy-duty industrial design suited to harsh operating environments. For B2B buyers, this means long service life, reduced downtime, and fuel-saving operation across Caterpillar excavators, wheel loaders, motor graders, compactors, dozers, and generator sets. Application verification by serial number is recommended before ordering, and global export is supported across North America, South America, Europe, the Middle East, Africa, Southeast Asia, Australia, and Central Asia.
