Caterpillar original Diesel Fuel Injector 10R-1000 229-5919 Replacement for OEM 359-7434 10R-0955 for C15 Engine Excavator, for heavy duty diesel engine application original new injector

Built for rigorous Caterpillar heavy-duty diesel engine operating conditions, the CAT 10R-1000 Electronic Unit Injector (EUI) is a direct-fit replacement component engineered for C15, C15 ACERT, C16, 3406E, CAT industrial power unit, and CAT marine propulsion engine platforms. Manufactured to meet or exceed OEM performance specifications, it supports seamless fitment during engine overhauls, routine maintenance, and component replacement for aftermarket and dealer service channels.

As part of the engine’s high-pressure fuel injection system, the 10R-1000 injector operates via ECM-controlled solenoid actuation to drive high-pressure fuel compression, precision nozzle opening, and optimized atomization directly in the combustion chamber. This design delivers precise fuel metering, improved combustion efficiency, lower fuel consumption, reduced smoke emissions, enhanced engine response, and extended engine service life. Every unit undergoes factory flow testing and performance verification, with heavy-duty construction and corrosion protection for reliable long-term operation.

The injector supports a broad range of global industrial sectors, including construction, mining, heavy-duty transportation, marine, oil and gas, power generation, and industrial operations, with compatibility for excavators, mining haul trucks, wheel loaders, diesel generator sets, and oilfield equipment. Backed by a 12-month warranty, it is suitable for fleet maintenance programs, dealer inventory stocking, and global aftermarket distribution to support consistent operational uptime.
