Engineered for demanding industrial diesel platforms, this common rail fuel injector assembly (OE 321-3600, cross-referenced to 10R-7938, 2645A753, and 320-3800) delivers precision fuel metering for C6, C6.4, and C6.6 diesel engines. Each unit is manufactured to OEM specifications and calibrated on professional test benches to verify flow rate and spray pattern consistency, ensuring reliable combustion performance across a wide range of operating loads and duty cycles typical of heavy-duty industrial applications.
Built with hardened alloy steel bodies, precision-ground internal components, and corrosion-resistant protective coatings, the injector is designed for long service life in harsh operating environments. High pressure injection technology and enhanced fuel atomization produce fine spray particles that support cleaner, more efficient combustion, helping equipment meet Tier III and regional emission requirements. Typical applications include 312D, 320D, and 323D excavators, 924H wheel loaders, D6K dozers, AP600D pavers, forestry machines, mining trucks, auxiliary power systems, agricultural irrigation and harvesting units, standby diesel generator sets, and marine harbor equipment.
For optimal service life, clean the injector bore thoroughly, replace sealing washers and O-rings, verify fuel rail pressure, check return fuel flow, calibrate as required, and perform a leakage test after installation. Diagnostic procedures include fault code checks, return flow testing, injector balance tests, spray pattern inspection, nozzle wear evaluation, and ECU signal confirmation. Maintain clean diesel fuel and replace fuel filters regularly to prevent contamination.
