Caterpillar original Caterpillar 235-9649 diesel fuel injector replacement for OEM common rail system new injector original new injector

Engineered for demanding diesel applications, the 235-9649 fuel injector is a direct replacement solution for C7, C9, and C-9 engines used across global heavy equipment operations. This common rail injector assembly is manufactured to original OEM standards and is cross-referenced with authorized part numbers 2359649, 236-0962, 217-2570, 235-2888, 10R-7225, 10R-7224, 236-0692, and 263-8218, giving distributors and service workshops broad interchange coverage for aftermarket fulfillment.

The injector delivers precision fuel metering, stable injection timing, and a high-quality spray pattern for improved atomization and combustion efficiency. Heavy-duty construction with wear-resistant internal components ensures high temperature resistance and low leakage performance under sustained heavy load conditions. Typical field applications include 330C, E330C, 330D, 336D, E336D, 320D, 315D, and 319D excavators, as well as loaders, generator sets, mining machinery, and industrial power units. Buyers should confirm compatibility using the old injector number, engine serial number, and parts catalog data before purchase.

Recommended service practice includes regular fuel filter replacement, use of clean diesel, water separator draining, injector return flow testing, and ECM fault code scanning. When installing, clean the injector bore, replace seals, inspect fuel lines, prime the fuel system, and perform injector calibration or coding if required. This part effectively addresses hard starting, rough idle, black smoke, power loss, and misfire faults.
