Caterpillar original 10R-7225 387-9427 263-8218 328-2585 Common Rail Diesel Fuel Injector Replacement for CAT C-9 Diesel Systems, for heavy duty diesel engine application original new injector

Engineered to match strict Caterpillar OEM specifications, the 10R-7225 remanufactured common rail diesel fuel injector is purpose-built for C9 and C9 ACERT diesel engine platforms. As an electronically controlled high-pressure injection component, it delivers precise fuel metering and optimized atomization to boost combustion efficiency, reduce fuel consumption, and cut exhaust emissions while maintaining consistent power output. Every unit is tested per Caterpillar factory standards to ensure reliable performance under extreme operating temperatures and heavy load conditions.

This injector supports a broad range of heavy-duty Caterpillar equipment across six core industrial sectors: construction, mining, power generation, industrial, marine, and agriculture. Verified compatible units include 330D and 336D excavators, 966H and 972H wheel loaders, C9 generator sets, industrial power units, and marine C9 engines. It cross-references with 249-0713, 387-9433, 387-9434 and their non-hyphenated formats, and customers must confirm compatibility with their engine serial number and emissions configuration before ordering.

For fleet and maintenance teams, the 10R-7225 reduces unplanned downtime and long-term operational costs via wear-resistant internal components and OEM-grade reliability. Installation must follow official Caterpillar service manual procedures, use OEM-approved sealing kits, and include ECM calibration when required. Pairing the injector with regular fuel filter changes, clean diesel fuel, and periodic performance testing maximizes its service life and sustains optimal fuel economy.
