Caterpillar original Common Rail Diesel Fuel Injector 250-1309 Cross Reference 10R-3264 10R-3265, Fuel Injector 10R-3258 Replacement for OEM, for C13 Excavator original new injector

Industrial parts suppliers, heavy equipment maintenance teams and fleet operators servicing harsh, high-demand operating environments can rely on the Caterpillar (CAT) 10R-3258 fuel injector for consistent OEM-equivalent performance across C13 diesel engine platforms. As a direct replacement component, it cross-references OEM part numbers 328-2574 and 3282574, and fits all C13 variants including ACERT, industrial, generator and marine models, with applications spanning construction, mining, transportation, power generation, marine, oil & gas and applicable agricultural equipment.

Manufactured as an electronic unit injector (EUI) for common rail diesel fuel systems, the 10R-3258 operates via ECM signals that activate its solenoid and needle valve to deliver precisely metered, finely atomized fuel directly into the combustion chamber. Its precision-engineered build, optimized spray pattern and corrosion-resistant, wear-resistant construction support stable power delivery, improved combustion efficiency, lower fuel consumption and reduced emissions, while extending overall engine service life under continuous heavy-duty use.

The injector comes with a 12-month warranty and offers neutral, OEM-style or customized packaging, with a 1-piece MOQ, global shipping, technical support, bulk order discounts, and OEM/private label services to accommodate varied B2B procurement needs. Customers must verify compatibility using the engine serial number, arrangement number and injector calibration code before purchase, and follow official installation and maintenance protocols to maximize service life.
