Caterpillar original 250-1309 Common Rail Diesel Fuel Injector for Caterpillar C13 Engine, Replacement for OEM 10R-3258, Compatible with Excavator 294-3002, 292-3666 original new injector

As a precision-engineered fuel system component built to strict Caterpillar OEM specifications, the 250-1309 diesel injector is purpose-built for all compatible CAT C13 12.5L inline six-cylinder engine variants, covering standard, ACERT, industrial, generator, and marine configurations. It supports a wide portfolio of heavy-duty CAT equipment including excavators, wheel loaders, articulated trucks, generator sets, marine propulsion systems, heavy-duty trucks, and industrial machinery, serving core sectors such as construction, mining, marine transport, power generation, and industrial manufacturing.

This electronically controlled diesel injector operates via ECM signal activation: high-pressure diesel enters the injector body before the solenoid triggers needle valve lift, atomizing fuel into fine droplets through precision multi-hole nozzle holes to optimize combustion. Manufactured with hardened internal parts, corrosion-resistant materials, and high-temperature tolerant structures to exact OEM tolerances, it delivers precise fuel metering, improved atomization, stable combustion, enhanced fuel economy, reduced emissions, and long service life even under harsh operating conditions.

Each 250-1309 injector is produced under ISO-certified quality standards, shipped in industrial export packaging, and comes with a 12-month warranty for B2B operational assurance. To maximize service life and support reliable long-term operation, users shall follow Caterpillar-approved installation and maintenance procedures, use OEM-quality fuel filters, keep diesel fuel clean, and conduct regular diagnostic checks including electronic scanning, fuel pressure testing, and injector balance testing.
