original 320-0655 Common Rail Diesel Fuel Injector Assembly for Perkins C6.6 C4.2 C6.4 Excavator Engine Parts 10R-7674 2645A751 original new injector

Engineered for demanding diesel applications, this common rail fuel injector assembly (OE 320-0655) delivers OEM-equivalent performance for C6.4 and C6.6 engine platforms, as well as Perkins 1106D, 1106D-E66TA, and 1106D-E70TA industrial power units. Manufactured under ISO9001-certified processes, the unit is factory calibrated and supplied in new condition, ready for direct replacement installation across excavators, loaders, generator sets, and industrial power plants.

Core construction combines premium alloy steel bodies with precision-ground needle valves and hardened steel components to withstand high injection pressures, elevated combustion temperatures, and corrosive operating environments. Precision nozzle technology ensures precise fuel metering, atomization consistency, and leak-free sealing under continuous duty cycles. Cross-references include 10R-7674, 2645A751, 2645A736, 2645A720, 306-9355, and 292-3755, providing broad compatibility for 320D, 321D, 323D, and 324D excavators, 938H, 950H, and 962H loaders, backhoe loaders, mining trucks, marine auxiliary engines, and emergency backup power systems.

Recommended installation torque is 40-45 Nm using a calibrated torque wrench, with ECM coding verification required after fitment. For extended service life, operators should use clean diesel fuel, replace fuel filters regularly, avoid contaminated fuel supplies, maintain proper rail pressure, and perform periodic injector testing. This injector is an ideal solution for fleet operators, remanufacturers, and industrial maintenance programs requiring reliable common rail performance.
