Engineered for the Caterpillar 3500 series diesel platform, the CAT 10R-1275 fuel injector is an electronic unit injector (EUI) supplied as a genuine replacement for the 3512B engine series. This diesel injector assembly cross-references directly with alternative part numbers 10R1275, 127-8222, 1278222, 0R-8477 and 0R8477, giving buyers a single, fully interchangeable sourcing option for multiple OE references. As a core component of the engine's fuel injection system, it is responsible for accurate fuel delivery through its precision nozzle unit.
The 10R-1275 is designed to fit a broad range of Caterpillar engines, including the 3512B, 3516B, 3508B, 3512C and 3516C models used across the CAT 3500 series family. This wide compatibility supports demanding applications such as generator sets, marine propulsion and marine generator systems, mining trucks, locomotives, oilfield equipment and industrial power units. Whether installed in a vessel, a power plant or heavy mining machinery, the injector integrates directly with the existing electronic unit injection system as a true replacement component.
For B2B buyers — including parts distributors, fleet maintenance teams and engine overhaul workshops — this OEM-quality injector offers a dependable balance of performance and value. Full interchangeability across five part numbers simplifies procurement and reduces inventory complexity, while the CAT 3512B series pedigree supports consistent fit and function. We supply this injector for single-unit replacement or bulk orders; contact our sales team for pricing, lead time and technical details.
