original 250-1314 Diesel Engine Common Rail Fuel Injector 375-4106 20R-3483 359-5469 20R-3477 10R-1290 new injector original new injector

Engineered specifically for the 3512B series, this OEM-specification fuel injector carries the primary OE number 250-1314 and delivers a direct-fit solution for operators of 3508B, 3512B, and 3516B diesel platforms including PM3512 and PM3516 configurations. The injector is manufactured from high-strength alloy steel with OEM-standard precision tolerances, ensuring correct seating geometry, leak-free sealing, and consistent fuel metering across high-pressure common-rail and direct-injection systems. Each unit is individually sealed and produced under ISO and manufacturing standards.

Comprehensive cross-reference coverage is provided through 10R-1290, 20R-1275, 392-0214, 386-1766, 229-0193, 150-4456, 126-7995, 114-6469, 0R-8892, and 0R-8690, enabling seamless replacement across the 3512B engine family without the need for additional adaptation. The advanced atomizer assembly produces a clean and uniform spray pattern, enhancing combustion efficiency, reducing smoke emissions, and supporting stable performance under continuous prime power, standby, and heavy-load operating cycles common in power generation, marine propulsion, mining, and oil and gas field applications.

Installation requires adherence to standard technical procedures: cleaning the injector bore and fuel passages, installing new O-rings and seals, inspecting the injector seat and tip for wear or carbon deposits, applying the manufacturer-specified torque value, performing a leak-down test, and verifying spray pattern and injection timing calibration. Routine inspection and timely replacement of the fuel injector help maintain fuel economy, protect the engine from combustion-related wear, and extend the service life of the 3512B, 3508B, and 3516B power units deployed in industrial, marine, and power generation environments worldwide.
