Caterpillar original Fuel Injector Cross Reference 230-3255, 376-0509, 392-0217, 10R-3255 Replacement for OEM, Compatible with Engines for Generator Set Marine Excavator Truck original new injector

Aligned with official Caterpillar quality specifications, the 10R-3255 is an original fuel injector assembly purpose-built for all CAT 3512B series diesel engine variants, including HD, marine, generator engine, and industrial power unit configurations. It supports a standardized suite of cross-reference part numbers recognized across Caterpillar’s global dealer networks, engine rebuild facilities, and industrial parts databases, enabling seamless part matching for cross-regional maintenance, repair, and overhaul operations.

Manufactured to strict OEM performance standards, this injector delivers precisely metered diesel fuel at calibrated timings to support optimal atomization, stable combustion, and consistent engine output under continuous heavy-load conditions. Its industrial-grade metallurgy and precision-machined components deliver high combustion temperature resistance and extended service life, while optimized spray patterns reduce excess fuel consumption and lower particulate emissions to improve operational efficiency for end-users.

Validated for 3512B-powered equipment across six core industrial sectors—power generation, marine, mining, oil and gas, construction, and industrial equipment—the 10R-3255 supports mission-critical use cases including backup generator sets, commercial marine propulsion systems, mining haul trucks, and offshore auxiliary systems. It is a reliable component for engine MRO providers, fleet operators, and industrial parts distributors serving critical infrastructure and continuous-duty industrial operations.
