Caterpillar original Fuel Injector: 10R-8501, for heavy duty diesel engine application, 235-1401, 10R-8500, 10R-0957 Common Rail Diesel Injector original new injector

Procurement teams sourcing reliable fuel system components for heavy-duty Caterpillar diesel platforms can rely on the CAT 10R-8501 remanufactured diesel fuel injector for consistent, application-matched performance. Designed for high-load diesel combustion systems, it delivers precise fuel metering, stable atomization, accurate injection timing and uniform cylinder-to-cylinder balance to support rated engine power, optimized fuel economy and extended service life. It is an industrial-grade component built to withstand continuous heavy-duty operating conditions.

The 10R-8501 is widely cross-referenced across aftermarket diesel parts catalogs, remanufacturing databases and heavy-duty truck parts channels, as a replacement for multiple CAT 0R, 10R, 100-series and 200-series injector numbers. It is commonly fitted to Caterpillar 3406E, C15, C15 ACERT and C16 engines, with use cases covering Class 8 trucks, vocational fleets, construction and mining equipment, generator sets and stationary industrial systems. Final fitment requires verification via engine serial number, removed injector part number, ECM calibration, fuel system configuration and trim code.

This remanufactured injector is sold as an individual replacement unit, exchange injector, or full set of 6 units for 6-cylinder engines, catering to diverse B2B needs for fleet maintenance, repair shops and diesel parts distributors. Indexed for OE number search matching to streamline sourcing, buyers may confirm core charge rules, configuration details and application requirements with suppliers before ordering to minimize fitment risks.
