Perkins original  250-1313 Diesel Engine Fuel Injector 10R-1285 10R1285 20R-0850 for Perkins C12 3512 3516 Excavator 797 793C TRUCK original new injector

The Perkins 250-1313 fuel injector assembly is a precision-engineered diesel fuel injection component designed for the Perkins 3512B engine series. Built to OEM quality specifications, this injector delivers accurate fuel metering and optimized atomization characteristics, ensuring stable combustion efficiency and consistent spray pattern performance across demanding operating environments. The component supports high-pressure fuel delivery, which contributes to improved combustion chamber distribution, reduced fuel consumption, and lower particulate emissions.

Engineered for heavy-duty industrial use, the 250-1313 injector enhances engine durability, responsiveness, and cylinder balance while maintaining stable idle performance. It is suitable for power generation systems, marine propulsion engines, mining equipment, offshore platforms, oilfield power units, industrial compressors, and similar heavy-duty diesel applications. The assembly is also referenced under the alternative part numbers 2501313 and CAT2501313, providing reliable cross-compatibility for replacement and remanufacturing requirements.

By installing the Perkins 250-1313 injector, operators benefit from reduced black smoke emissions, lower maintenance costs, longer engine service life, and improved overall engine reliability. Before installation, technicians should verify the OEM number 250-1313, confirm the 3512B engine model, inspect the fuel rail system, replace sealing components, and verify fuel cleanliness. Proper seating tools and specified torque values must be applied during installation, followed by leak testing, fuel pressure verification, cylinder balance testing, and ongoing parameter monitoring to ensure optimal injector performance.
