original 2645A753 Diesel Engine Fuel Injectors for 323D C6.6 C6.4 1106D-E66TA Truck Engine Spare Parts 321-3600 3213600 10R7938 2645A745 10R-7667 2645A752 original new injector

Engineered for heavy-duty industrial service, this common rail diesel fuel injector (OE 2645A753) delivers precision fuel metering and superior atomization for C6, C6.4, and C6.6 inline 6-cylinder water-cooled engines. Cross-referenced with 330-8752, 7C-6011, 10R-7217, 2645A754, and 2645A755, the unit is a direct-mount OEM replacement suitable for excavators, wheel loaders, backhoe loaders, generator sets, industrial power units, and marine auxiliary engines operating in demanding environments.

Manufactured from hardened alloy steel with a multi-hole precision nozzle, this electronically controlled injector operates at 1800–2500 Bar to support modern high-pressure common rail systems. Optimized spray geometry improves combustion efficiency, reduces emissions, and enhances diesel fuel economy, while corrosion-resistant surface treatments protect against moisture, contamination, and oxidation. Wear-resistant internal components ensure stable engine performance, smooth idle, and responsive throttle response across continuous industrial duty cycles, extending service life in construction, mining, agricultural, and power generation applications.

Installation is straightforward using OEM torque specifications: clean the injector bore, renew O-rings and copper washers, verify fuel return line connections, prime the system, and scan the ECM for fault codes to confirm injection balance. Recommended service intervals include fuel filter inspection every 250 hours, replacement every 500 hours, injector performance testing every 1000 hours, and calibration checks every 2000 hours—delivering reliable uptime for fleet operators, OEM equipment builders, and industrial maintenance distributors worldwide.
