original 2645A734 Fuel Injector Diesel Engine Spare Parts for 1104D-E44TA C6.5 C6.4 C4.4 C4.2 Excavator Repair 2645A718 2645A747 292-3780 310-9067 10R-7672 original new injector

Engineered as a direct OEM-grade replacement, the 2645A734 diesel common rail fuel injector delivers precise fuel metering and reliable atomization for C6.6 and C4.4 industrial power units, including Perkins 1104D-E44TA, 1106D-E66TA, and 1106D engines. Manufactured through CNC precision machining to strict OEM specifications, this injector is fully interchangeable with cross reference numbers 320-0680, 292-3780, 306-9380, 10R-7672, 2645A718, 2645A747, 2645A747R, and 4226779M1, providing procurement flexibility for fleet operators, distributors, and aftermarket suppliers.

The injector features advanced multi-hole nozzle technology for enhanced fuel atomization and complete combustion, high-pressure resistance capable of withstanding extreme common rail operating pressures, and heat-treated internal components that ensure long service life under continuous industrial duty cycles. Corrosion-resistant construction supports operation in harsh environments and with variable fuel qualities. Benefits include improved fuel efficiency, higher engine power output, reduced exhaust emissions, better cold-start performance, and stable combustion, making it ideal for excavators, wheel loaders, backhoe loaders, diesel generator sets, agricultural machinery, and mining equipment across global markets.

Recommended installation practices include cleaning the fuel rail and injector seat, replacing sealing washers, applying OEM torque specifications, bleeding the fuel system, and performing ECM calibration where required. Regular filter replacement and clean diesel fuel usage help prevent common diagnostic codes such as Fuel Rail Pressure Deviation, Injector Circuit Fault, and Cylinder Contribution Fault. Backed by a 12-month warranty.
