The Caterpillar CAT C9 C-9 Diesel Fuel Injector 235-9649 2359649 CA2359649 is engineered as a direct replacement injector for the Caterpillar C9 / C-9 diesel engine platform, serving excavator, construction machinery, and industrial power unit applications. This common rail fuel injector is built for heavy-duty service environments, with precision fuel delivery that maintains stable injection output and supports efficient combustion across demanding operating conditions. Engine-specific fitment ensures correct installation on CAT C9 Industrial, C9 Excavator Engine, and C9 Power Unit / Generator applications.

Designed for replacement-ready installation, the injector features controlled spray pattern geometry that helps reduce smoke and improve fuel atomization. Heavy-duty construction allows the component to perform reliably in off-highway diesel equipment, while the global parts search compatibility indexed by multiple OE, replacement, and cross-reference numbers simplifies sourcing for maintenance teams, engine rebuilders, and diesel repair workshops. Authorized cross numbers include 236-0962, 235-2888, 10R-7224, 217-2570, 188-8739, 172-5780, and 235-2887.

The injector is compatible with CAT 330C, E330C, 330CL, 330CMH, D6R, 973C, and 627G excavators, dozers, track loaders, scrapers, and industrial generator sets. To preserve service life, clean high-quality diesel fuel and properly maintained filtration are recommended, and the injector should be inspected during fuel system service or engine overhaul. The component is supplied in clean, dry, sealed packaging to protect precision internal surfaces from contamination.
