Caterpillar original for Caterpillar C11 C13 C15 Engine Replacement for OEM Fuel Injector 10R-1305 Cross Reference10R-3262 10R-1274 Replacement for OEM 239-4908 Construction original new injector

For fleets and heavy equipment operators relying on Caterpillar C11 diesel power, the 10R-1305 Electronic Unit Injector (EUI) is an OEM-spec replacement component engineered for consistent, heavy-duty performance. It is compatible with all verified C11 engine variants, including C11 ACERT, industrial power units, generator set engines, marine propulsion engines, and on-highway truck engines. The injector serves core industrial sectors spanning construction, mining, transportation, industrial power generation, marine operations, and agricultural production, and is widely available through global OEM replacement and aftermarket supply chains.
Integrating fuel pumping, metering, and injection functions into one compact assembly, the 10R-1305 operates in sync with the engine’s Electronic Control Module (ECM): a solenoid valve receives calibrated injection commands, the internal plunger builds extreme fuel pressure, and the precision nozzle atomizes fuel directly into the combustion chamber. This refined design delivers precise fuel metering, superior atomization, improved horsepower, reduced particulate emissions, enhanced cold-start performance, and lower fuel consumption, even under harsh operating conditions.
Built to OEM-level manufacturing standards with industrial-grade durability, the 10R-1305 offers long service life and reliable performance under demanding workloads, backed by a 12-month warranty. It cross-references to part numbers 249-0713, 2490713, 387-9433, and 3879433; buyers should verify fitment via engine serial number before ordering, as compatibility varies by production batch, emissions level, and regional market specification. Adhering to Caterpillar service guidelines and conducting routine fuel system maintenance supports optimal long-term operation.
