Caterpillar original Diesel Fuel Injector 10R-7230 Replacement, Cross Reference 10R7221, 10R7225, 10R-7668, Fits Caterpillar C15 C18, Excavator, 988K 990K 390F L 395 original new injector

As a precision-manufactured original remanufactured diesel fuel injection component built exclusively for Caterpillar C18 series heavy-duty engines, the 10R-7230 injector meets stringent Caterpillar OEM specifications for fit, form, and function. It supports direct replacement of the factory 10R-7230 part and is cross-compatible with listed interchange numbers, though final fitment should always be verified via engine serial number, VIN, or official OEM parts documentation to account for variant-specific configurations.

Operating as part of the engine’s common rail fuel system, the injector receives timed electrical signals from the engine control module to open its needle valve, atomizing pressurized diesel into a fine mist for optimized combustion. This precision operation delivers tangible operational benefits including improved fuel efficiency, reduced particulate emissions, enhanced horsepower output, and more reliable cold-start performance, while supporting extended engine service life under heavy, continuous use.

The 10R-7230 is suited for a broad range of industrial applications spanning mining, construction, marine propulsion, power generation, oil and gas operations, and industrial manufacturing, with use cases covering excavators, mining trucks, wheel loaders, generators, marine engines, and oilfield power units. It offers B2B buyers consistent heavy-duty performance, OEM-grade quality, and long service intervals to minimize equipment downtime across demanding deployments.
