Caterpillar original Common Rail Fuel Injector 459-8473 for Heavy Machines, 10R-7222, C7 C9 Engine, Cross Reference 10R-7224, Replacement for OEM 387-9433 original new injector

The Caterpillar 10R-7222 fuel injector is a precision-engineered heavy-duty diesel injection component designed for Caterpillar C9 and C9 ACERT engines, with additional compatibility across Industrial C9, Generator Set C9, 3126B, and 3126C platforms. Manufactured to OEM specifications and cross-referenced against 236-2010, 236-2011, and 236-2012, it is a direct OEM replacement for CAT wheel loaders (950H, 962H, 966H, 972H), motor graders (120M, 140M, 160M), excavators, generator sets, and industrial power units serving construction, mining, agricultural, marine, and power generation applications.

Built with micron-level nozzle machining, high-pressure calibration, and OEM tolerance control, the injector delivers accurate fuel metering and optimized atomization through precision nozzle holes. Hardened steel components, wear-resistant internal surfaces, and corrosion-resistant treatment ensure long service life under demanding duty cycles. Its optimized spray pattern improves combustion and thermal efficiency, cutting fuel consumption and exhaust smoke while supporting stable idle operation, faster throttle response, and maximum engine power output.

Operating within a high-pressure common rail fuel system, the solenoid-actuated injector responds to electronic control signals for precise injection timing. Installation requires a clean injector bore, new sealing washers, fuel rail pressure verification, and post-installation ECU diagnostics with leak testing. Every unit is manufactured to OEM specifications and backed by a 12-month warranty, helping distributors, fleet operators, and repair facilities minimize downtime. Competitive wholesale pricing and global shipping availability support B2B sourcing programs worldwide.
