Caterpillar original 20R-1917 Diesel Engine Common Rail Fuel Injector 293-4072 for CAT C9 330D 340D 336D Excavator, Replacement for OEM 265-8106, Cross Reference 10R-7222 original new injector

For procurement and maintenance teams managing Caterpillar diesel equipment fleets, the 20R-1917 fuel injector is a purpose-built high-pressure injection component designed exclusively for C9 and C9 ACERT engine platforms. Each unit supports clear part number verification via its official OE marking 20R-1917 (with format variants 20R1917 and CAT20R1917), and cross-references fully with validated interchange numbers 10R-7220 and 326-4703 to eliminate fitment errors and reduce risks of mismatched parts.

Engineered as an electronic common rail injector, the 20R-1917 uses ECM-controlled injection timing and precision-machined nozzle assemblies to deliver accurate fuel metering and fine atomization, supporting more complete combustion, lower fuel consumption, reduced exhaust emissions and stable engine output. Its hardened alloy steel construction withstands extreme fuel pressure, continuous duty cycles, vibration and thermal stress, with every unit factory tested and calibrated to meet or exceed OEM tolerances for direct, reliable fitment.

The injector is compatible with a wide range of heavy-duty diesel equipment across construction, mining, power generation, marine and general industrial sectors, including excavators, wheel loaders, generator sets and marine propulsion systems. It comes with a 12-month warranty for global market coverage, and aligns with standard routine maintenance practices to extend service life and minimize unplanned equipment downtime in demanding operating environments.
