Perkins original Perkins 328-2574 Fuel Injector for C7 C9 Diesel Engine Excavator new injector original new injector

Engineered specifically for the Perkins C9 engine platform, the 328-2574 fuel injector delivers precise fuel atomization through advanced precision nozzle technology. Each injector is OEM calibrated to ensure consistent fuel delivery rates, supporting improved fuel economy and better combustion efficiency across demanding operating conditions. The high-pressure operation capability, combined with wear-resistant materials and anti-corrosion surface treatment, guarantees long service life in heavy-duty industrial environments.

This injector assembly serves as a direct replacement for OE numbers 236-2671 and 236-2672, maintaining factory-level performance specifications for Perkins C9, C9.3, C7, and C18 diesel engines. The component integrates seamlessly with the high-pressure common rail fuel system found in excavators such as the 330D, 336D, and 340D, motor graders including the 140M and 160M, wheel loaders like the 973C, and various compactors and dozers in the 627G, 637D/E/G and 814F II through 816F II series. Installation ensures restored engine power output and reduced smoke emissions.

Routine maintenance intervals should follow standard Perkins service guidelines, including daily leakage inspection, 500-hour electrical connector and fuel rail pressure checks, 1000-hour flow testing and ECM diagnostic scans, and 2000-hour complete injector evaluation including spray pattern verification and seal replacement. Operators in construction, mining, power generation, oil and gas, forestry, and infrastructure sectors rely on this injector to lower operating costs while maintaining dependable performance in generator sets, surface mining equipment, petroleum transmission packages, and road construction machinery.
