Caterpillar original 20R-0760 Fuel Injector Replacement for 3408 3412 C3412 D9R D9N 637G 631G 771D 375 5080 Excavator Repair original new injector

The Caterpillar 20R-0760 fuel injector assembly is engineered specifically for the CAT 3412, 3412B, and 3412C diesel engine series, delivering OEM-level fuel delivery performance across demanding industrial operating environments. Manufactured from high-strength alloy materials and calibrated to original equipment standards, this injector ensures precise atomization, consistent injection pressure, and reliable cold-start capability for generator sets, marine propulsion systems, and heavy-duty industrial power applications.

Featuring an industrial-grade precision nozzle and robust internal components, the 20R-0760 injector is built to withstand the harsh conditions encountered in mining operations, offshore platforms, oilfield drilling rigs, and continuous-duty power generation stations. Its heavy-duty construction supports long service life and stable combustion efficiency, while precision-machined spray patterns promote excellent fuel economy, reduced exhaust emissions, and lower overall operating costs. Each unit is 100% performance tested before shipment to verify flow rate, atomization quality, and sealing integrity under simulated load conditions.

Designed as a direct OEM replacement and cross-compatible with part numbers 0R-3052 and 4W-7015, the 20R-0760 injector integrates seamlessly into existing CAT 3412 fuel systems without modification. Proper installation requires cleaning the mounting area, inspecting the injector seat, replacing sealing components, applying OEM torque specifications, bleeding the fuel system, and verifying for leaks during initial startup. Routine maintenance—including clean diesel fuel usage, regular filter replacement, and scheduled engine diagnostics—helps maintain optimal injector performance and extends overall engine service life.
