Original Common Rail Injector 418-3229 392-1368 20R-2479 for C4.4 C6.6 320D 323D Excavators Generators and Construction Machinery original new injector

Engineered for demanding industrial diesel platforms, the 418-3229 Fuel Injector delivers OEM-level fuel injection accuracy for the C4.4 engine family, including the C4.4 ACERT, C4.4 Industrial, C4.4 Generator, and both Tier 3 and Tier 4 configurations. Manufactured with precision nozzle technology and high-pressure resistance, this common rail injector assembly ensures excellent fuel atomization, precise metering, and stable engine performance under continuous heavy-duty operation. Authorized cross references include 10R-7675, 387-9433, 2645A749, and 32F61-00062.

This injector is widely deployed across 416F, 420F, 430F, and 444F Backhoe Loaders, 907M, 908M, and 914M Wheel Loaders, Telehandlers, Generator Sets, and stationary industrial engines. It also supports mining auxiliary power units, agricultural tractors and harvesters, diesel generator sets, emergency backup systems, compressors, pumps, material handling equipment, and marine harbor engines. Superior wear resistance and long operational life help reduce downtime, improve combustion efficiency, lower exhaust emissions and particulate formation, and enhance cold start performance and throttle response.

For optimal service life, use ultra-clean diesel fuel, replace filters on schedule, and avoid water contamination. Before installation, inspect fuel rail cleanliness, replace sealing washers, verify injector bore condition, flush contaminated fuel lines, and perform injector coding if required by the engine ECM. After installation, conduct leak testing, verify rail pressure, confirm injector balance rates, and clear diagnostic fault codes to resolve rough idle, power loss, or smoke-related fault codes.
