original 4P-9076 Common Rail Diesel Fuel Injector for 3508 3512 3516 Engine 777B 785 789 Mining Dump Truck Replacement for OEM 4P9076 0R-3052 original new injector

Engineered for demanding heavy-duty operation, the 4P-9076 fuel injector delivers OEM-grade fuel atomization and metering accuracy for the 3512A diesel engine platform. Manufactured to strict OEM specifications, this injector assembly serves as a direct replacement for legacy part numbers 0R-9076, 0R2921, 7E3382, 9Y1785, and 0R2836, ensuring seamless fitment across 3508, 3512, 3512A, and 3516 series engines used in generator sets, marine propulsion, and industrial power units.

The precision nozzle design provides optimized spray geometry that improves fuel economy, increases engine power output, and reduces black smoke emissions. Each unit is 100% performance tested and flow-calibrated to OEM standards, delivering stable frequency and voltage output for continuous power generation applications in data centers, hospitals, utility power stations, and telecommunications facilities. Heavy-duty construction and corrosion-resistant materials extend service life under high-load duty cycles in mining trucks such as 777B, 777C, 785, 789, and 994, as well as D11N and D11R equipment.

Installation follows standard OEM procedures: disconnect the fuel supply, remove the old injector, clean the bore, install the new unit to torque specification, bleed the system, and verify operation. Backed by a 12-month warranty, this replacement injector is supplied to global export markets including North America, Europe, the Middle East, Africa, and Southeast Asia for reliable industrial diesel service.
