original OR-3051 Fuel Injector Assembly for 3512A Engine Construction Machinery Diesel Fuel Injection Nozzle Replacement 7E-3383 7C-0345 7C-4175 original new injector

Engineered for demanding heavy-duty diesel applications, the OR-3051 fuel injector delivers precision fuel atomization and reliable high-pressure performance across the 3512A, 3512, 3508, 3508C, and 3516 engine platforms. This single-port direct diesel injector is manufactured from alloy steel with corrosion protection, ensuring durability in industrial, marine, oil & gas, and mining environments where operational uptime is critical. Cross-referenced numbers include 0R-3051, 4P-9075, 7E-3381, and 9Y-4543 for verified interchangeability.

Built with industrial precision machining and multi-point calibration, the OR-3051 injector optimizes fuel delivery and combustion efficiency, reducing soot output and improving overall engine performance. Available in both new and remanufactured configurations, it meets OEM and aftermarket quality benchmarks for consistent flow rate, spray pattern, and long-term service life under harsh operating conditions. Typical deployment scenarios include power gensets, petroleum module installations, marine propulsion drives, and mining power platforms across North America, Europe, the Middle East, Asia, and Africa.

Installation requires a clean fuel system, new seals, torque tightening to manufacturer specifications, fuel bleeding, and operational verification at idle and full load. Routine visual inspection, scheduled filter replacement, and periodic spray-flow testing help prevent common failure modes such as hard starting, black or white smoke, power loss, and uneven idle caused by wear, leakage, or blockage. This injector is a proven replacement solution for global B2B fleet operators.
