Caterpillar original Replacement Fuel Injector 10R-0956 for C15 C-15 C-16 3406E, Cross Reference 2113027, 211-3023, 10R7231 for Excavator Diesel Engine Parts original new injector

Engineered as a purpose-built Cat Reman component, the 10R-0956 (compact part number 10R0956) is an electronic unit injector designed exclusively for Caterpillar heavy-duty diesel engines, with confirmed compatibility for low-sulfur and low-lubricity diesel formulations. Installed in the cylinder head’s fuel injector bore (typically six units per inline six-cylinder engine), it performs four critical fuel system functions: metering precise fuel volumes, pressurizing fuel to required levels, atomizing fuel for optimal combustion, and delivering fuel directly to the combustion chamber at exact timing.

The injector supports a broad range of cross-referenced part numbers to streamline global aftermarket sourcing, inventory matching, and replacement searches for maintenance teams. It is primarily specified for Caterpillar 3406E, C15, C-15, C16, and C-16 inline six-cylinder diesel engines, with use cases across heavy-duty highway trucks, construction and mining equipment, marine auxiliary engines, generator sets, oilfield power units, and high-load engine overhaul projects. Strict fitment verification is required before ordering or installation, including checks of engine model, serial number prefix, ECM calibration, injector trim code, emissions configuration, and original part number.

Built to withstand demanding industrial operating conditions, the remanufactured 10R-0956 supports stable fuel delivery, improved combustion efficiency, reliable engine response, idle quality, consistent emissions performance, and long service life for high-load operations. It is suited for diesel repair workshops, fleet operators, engine rebuilders, mining contractors, industrial engine users, parts wholesalers, and importers seeking a specification-matched original replacement injector for CAT diesel platforms.
