Caterpillar original Caterpillar 10R-4762 387-9429 295-1409 243-4503 328-2582 Diesel Fuel Injector Assembly for C7 Engine new injector original new injector

Engineered for professional fleet workshops and industrial engine rebuilders, the 10R-4762 HEUI diesel fuel injector delivers a dependable replacement solution for C7-series diesel engines. This electronic unit injector is designed to restore stable fuel delivery, reduce exhaust smoke, improve combustion efficiency, and support engine power recovery in demanding operating conditions. Interchangeable with 10R4762R, EX634762, 222-5962, 238-9808, 241-3239, 243-4503, 295-1409, 328-2584, 387-9429, and 20R-8058, it offers wide cross-compatibility for aftermarket sourcing and inventory consolidation.

The injector serves C7 7.2L, C7 industrial, C7 generator set, and C7 on-highway engine platforms installed in commercial trucks, buses, RVs, generator sets, industrial power units, construction machinery, mining support equipment, and agricultural machinery. It provides consistent flow characteristics, stable electrical response, a clean nozzle spray pattern, and reliable sealing surfaces. Because the HEUI system relies on both fuel supply pressure and high-pressure engine oil actuation under ECM control, correct trim-code compatibility and calibration are essential for optimal performance.

For long service life, verify the injector number, engine serial number, and ECM requirements before installation. Clean the injector bore, inspect the fuel and oil systems, replace all seals, and complete trim-code programming after fitment. Symptoms such as hard starting, rough idle, misfire, or power loss should be professionally diagnosed, as fuel pressure, oil pressure, wiring, or ECM issues may share similar signatures.
