Caterpillar original Diesel Fuel Injector for Excavator, 10R-3265, Caterpillar C15 C18 Engine, Cross Reference 244-7716, Replacement for 276-8307, 291-5911 original new injector

Identified by Caterpillar as a Cat Reman Fuel Injector, the 10R-3265 is an industrial-grade diesel fuel injection component engineered for heavy-duty Caterpillar engine platforms. It delivers precisely metered diesel fuel into the combustion chamber at the exact timing point, atomizes fuel into a fine spray to optimize air-fuel mixing, and supports stable combustion. Its performance directly impacts engine power output, fuel economy, exhaust emissions, idle smoothness and starting performance, while a properly functioning unit also reduces smoke and protects engines from abnormal combustion damage.

This injector is primarily designed for Caterpillar C15 engines, and is commonly cross-listed in aftermarket databases for C18, C27 and C32 platforms, with C16-related applications requiring careful verification. It fits a wide range of CAT heavy equipment, including excavators, motor graders, wheel loaders, dozers, as well as marine engines, generator sets and mining machinery. All compatibility and cross-reference part numbers must be confirmed via engine serial number, original injector tag, equipment model and ECM calibration before purchase or installation.

Multiple condition options are available, including genuine reman, aftermarket new, rebuilt and OEM-quality replacement units. Cat Reman variants use specialized metallurgy, proprietary manufacturing processes, extensive testing and engineering updates to deliver like-new performance, with wear-resistant design and precision fuel delivery. It is a reliable fuel system solution for on-highway, off-highway, industrial, construction, mining, marine and power generation applications.
