Caterpillar original Rail Fuel Injector 10R-2828 C9 Replacement for OEM 387-9436, for heavy duty diesel engine application, 20R-8060, 265-8106 for Excavator original new injector

As a genuine Caterpillar component built to strict OEM specifications, the 10R-2828 electronic unit injector is precision-engineered for C9 and C9 ACERT diesel engine platforms used across heavy-duty off-highway and industrial equipment. It serves as a direct OEM replacement for cross numbers 249-0713 and 328-2574, compatible with 330D/336D excavators, loaders, graders, generator sets, marine, mining, oilfield and road construction equipment.

Paired with the Electronic Unit Injection (EUI) system, it receives real-time ECM signals to adjust fuel metering per engine load, speed, intake pressure, coolant temperature and fuel demand. Its precision-ground plunger and matched nozzle generate ultra-high pressure and atomize fuel finely, optimizing combustion to cut fuel use, lower emissions, reduce smoke, improve cold starts, stabilize power and reduce engine wear. Corrosion-resistant, high-temperature materials and factory testing ensure long, reliable service life.

To avoid fitment errors, always verify compatibility via engine serial number, arrangement number and equipment serial number before ordering. Follow official installation practices: clean the injector bore, replace all seals, inspect lines and wiring, use OEM torque values, bleed system air, verify coding if required and run post-installation ECM diagnostics. Use high-quality diesel, replace filters regularly, prevent water contamination, avoid prolonged idling and conduct routine checks to maximize injector lifespan and reduce unplanned equipment downtime.
