Caterpillar original Diesel Common Rail Fuel Injector 7E-2269 10R3053 0R-1759 for Caterpillar 3500A 3508 3512 3516 3056E 3056T 3054T Excavator Replacement for OEM 7E-3382 original new injector

Engineered exclusively for the Caterpillar 3512A V12 diesel engine platform under strict OEM specifications, the CAT 10R3053 diesel fuel injector serves as a core precision component in high-pressure fuel delivery systems. It is validated to replace part number 340-3410 and cross-reference 3403410, and fits 3500 Series engines deployed across power generation, marine propulsion, mining, heavy construction, and oil & gas sectors, supporting equipment ranging from industrial generator sets to offshore oil platform machinery.

Constructed with precision-machined hardened alloy steel components and a calibrated multi-hole nozzle, this injector delivers precise fuel metering and optimized atomization under extreme high-pressure, high-temperature operating conditions. Its corrosion-resistant surface treatment withstands fuel contamination and harsh industrial environments, while its direct-fit design requires no on-site modification. Every unit undergoes 100% flow testing and calibration to guarantee consistent spray performance, stable combustion, improved fuel efficiency, and reduced exhaust emissions.

For B2B equipment operators and maintenance providers, the 10R3053 injector helps restore engine power output, reduce unplanned downtime, lower long-term maintenance costs, and extend overall engine service life. It comes with a 12-month warranty, and professional installation per OEM torque guidelines is recommended to ensure optimal performance and service life for heavy-duty continuous operation.
