Caterpillar original Common Rail Fuel Injector 241-3400 Replacement for OEM 222-5961 Cross Reference 268-1835, 10R-4763 for C7 C9 Engine Excavator E324D E325D original new injector

Built for demanding heavy-duty diesel operations, the Caterpillar 241-3400 fuel injector is a precision-engineered fuel injection component purpose-built for CAT C7 series diesel engines. It is compatible with all C7 variants including C7 ACERT, industrial, marine and generator-specific C7 engines, and fits a wide range of CAT equipment such as excavators, wheel loaders, motor graders, diesel generator sets and industrial power units. It serves industrial sectors spanning construction, mining, marine propulsion, power generation, agriculture and commercial transportation.

Manufactured to OEM equivalent specifications, this electronic unit injector (EUI) adopts high-pressure fuel delivery technology and electronically controlled injection timing to deliver precise fuel atomization and optimized spray patterns. These features improve combustion efficiency, reduce fuel consumption and exhaust emissions, enhance cold-start performance and engine response, and extend the component’s service life. It is made of high-strength alloy steel with hardened internal components and corrosion-resistant materials, and every unit passes 100% leak testing under strict quality control procedures.

The 241-3400 injector is available in both new and remanufactured conditions, and comes with 12 months of warranty packed in industrial export standard packaging. For reliable operation, installers must follow Caterpillar torque specifications, use approved tools, bleed the fuel system after installation and conduct ECU calibration if required. Routine maintenance includes using clean diesel, replacing fuel filters regularly and monitoring engine performance to reduce unplanned downtime.
