Caterpillar original Diesel Fuel Injector for Excavator Truck, 10R-3263 for C15 Engine, Cross Reference 244-7716, Replacement for OEM 253-0614, 253-0617 original new injector

As a precision-engineered diesel fuel injection component purpose-built for Caterpillar heavy-duty engine platforms, the 10R-3263 fuel injector follows strict OEM-equivalent specifications to guarantee proper fit and reliable baseline performance. It is fully compatible with CAT C15 and C15 ACERT engine variants, including industrial, marine, and generator-specific C15 models, and cross-references to 249-0713 (2490713) and 328-2574 (3282574) for straightforward part verification.

As an electronic unit injector (EUI), it operates in tandem with the engine’s electronic control module (ECM), which monitors real-time operating parameters to adjust injection timing and fuel delivery. The unit generates high-pressure fuel internally, opens its nozzle on ECM command, and atomizes fuel into the combustion chamber to optimize combustion efficiency, reduce fuel consumption and exhaust emissions, stabilize power output, and extend engine service life. It also features wear-resistant components, high-pressure durability, and corrosion protection for long operational life.

This heavy-duty injector supports a broad range of industrial use cases across global markets, fitting equipment such as heavy-duty trucks, construction and mining machinery, diesel generator sets, marine engines, industrial power systems, agricultural equipment, and oil and gas machinery. Every unit is tested prior to shipment, covered by a 12-month warranty, and packed in export-standard packaging to meet global B2B procurement requirements.
