original 250-1314 Diesel Fuel Injector for 3512B 3516B 3508B E3512B Engine Common Rail Injector Excavator Dozer Diesel Engine Parts Replacement original new injector

Engineered for demanding heavy-duty diesel platforms, the 250-1314 Fuel Injector is a high-pressure fuel injection component built to OEM specification for the 3512B, 3508B and 3516B engine series. It is fully cross-referenced with 10R-1290, 20R-1275, 392-0214, 386-1766, 229-0193, 150-4456, 126-7995, 114-6469, 0R-8892 and 0R-8690, making it a direct replacement for prime-power gensets, marine propulsion units, mining haul trucks and offshore power modules operating under continuous high-load duty cycles.

Each injector features OEM-precision machining with tight dimensional tolerances, an advanced atomizer nozzle delivering clean and uniform spray patterns, and high-strength alloy steel construction for superior mechanical durability. Corrosion-resistant materials and a thermal-stress-optimized design ensure stable performance across extreme operating environments, from Middle East oil & gas fields to Asia-Pacific construction sites and African mining operations. ISO-compliant quality assurance and individually sealed packaging guarantee that every unit meets consistent industrial standards.

Recommended installation procedure includes cleaning the injector bore and fuel lines, replacing all O-rings and seals with new components, inspecting the injector seat and tip, applying the correct torque sequence, performing a leak test, and verifying spray pattern and timing calibration. Backed by an available OEM warranty, this injector supports PM3512 and PM3516 platforms globally with reliable, long-service-life fuel delivery.
