Caterpillar original Caterpillar 10R-7230 diesel fuel injector replacement for OEM common rail new injector original new injector

The Caterpillar 10R7230 fuel injector is a genuine replacement component engineered for CAT C15, C15 ACERT, C15 SDP, C16, and 3406E diesel engines. Built with high-strength alloy steel construction and precision-machined nozzle technology, this HEUI (Hydraulically actuated Electronic Unit Injector) assembly delivers consistent fuel atomization and accurate metering across demanding operating conditions. OEM-calibrated fuel flow rates ensure direct compatibility with existing engine management systems, eliminating the need for extensive modifications during installation.

Designed for heavy-duty industrial, on-highway, marine, and power generation applications, the 10R7230 injector withstands severe duty cycles while maintaining stable injection pressure. Cross-referenced to 2360962, 3282574, 20R8064, 3879433, and 2490713, this assembly serves as a direct equivalent for fleets operating Caterpillar-powered Peterbilt, Kenworth, and Freightliner trucks, as well as CAT excavators, wheel loaders, mining trucks, drilling machinery, generator sets, and marine propulsion units. The corrosion-resistant surface treatment and wear-resistant internal components extend operational lifespan in harsh environments.

Installation follows standard OEM procedures, including thorough cleaning of the injector bore, inspection of the injector seat, replacement of O-rings and seals, and torque application per manufacturer specification. Proper fuel system priming, secure electrical harness connection, and post-installation leak inspection ensure optimal injector performance. Routine maintenance—including the use of ultra-clean diesel fuel, regular filter replacement, avoidance of water contamination, and periodic injector balance testing—helps maintain combustion efficiency, reduce exhaust emissions, lower fuel consumption, and preserve overall engine reliability.
