Caterpillar original Common Rail Fuel Injector, Cross Reference 10R-0958, 211-3022, 374-0750, 253-0614 Replacement for OEM, for CAT C15 Engine Excavator E365C E374D Diesel Parts original new injector

The Caterpillar 253-0614 Fuel Injector is a precision-engineered diesel injection component built for demanding heavy-duty operations in the transportation, mining, construction, marine, oilfield, and power generation industries. Manufactured to OEM-equivalent specifications and supplied in brand-new condition, it ensures accurate fuel atomization, optimized combustion efficiency, lower emissions, enhanced power output, and extended engine life, maintaining dependable performance under continuous high-load operation, elevated ambient temperatures, and severe-duty environments.

Designed for Caterpillar's high-performance diesel platforms, this injector fits C15, C15 ACERT, C15 ATAAC, C16, 3406E, Industrial C15, and Marine C15 engines. Typical installations include Peterbilt, Kenworth, and Freightliner trucks, CAT wheel loaders, excavators, mining trucks, generator sets, marine power systems, and industrial oilfield equipment. For sourcing flexibility, the unit interchanges with OEM numbers 253-0614 and 2530614, remanufactured numbers 10R7224 and 10R7222, cross-reference numbers 2490713, 3282574, 3879433, and 3879434, plus service replacement numbers 20R2057 and 20R2058.

Inside the combustion system, the injector acts as a high-precision metering device: the ECM calculates fuel demand from engine speed, load, throttle position, and intake parameters, then signals the solenoid to open the nozzle valve, atomizing fuel into microscopic droplets for efficient combustion. This precise delivery reduces particulate matter, nitrogen oxides, and fuel consumption while improving fuel economy, engine response, and smoke levels. Each unit carries a 12-month warranty and is offered in neutral packaging or custom branding for distributors, fleets, and maintenance providers.
