original Diesel Fuel Injector 20R-8061 C9 Engine Fuel Components Replacement for OEM 20R-8060 387-9435 20R-8427 new injector original new original new injector

The 20R-8061 fuel injector is a precision-engineered OEM replacement component specifically designed for C9, C9.3, and C9 ACERT engine platforms. Manufactured to original equipment standards, this high-pressure common rail injector incorporates a hardened alloy steel body, precision-ground internal components, and advanced nozzle technology to deliver consistent atomization and accurate fuel metering across demanding industrial duty cycles. The injector is fully interchangeable with 287-8061, 10R-8020, 147-2412, and 268-8061, providing direct-fit compatibility without modification.

This injector integrates seamlessly with C9 engine management systems, where the electronic control unit commands injection timing and duration while the high-pressure fuel system supplies atomized diesel into the combustion chamber. The result is improved fuel economy, reduced exhaust emissions, stable idle operation, faster cold starting, and increased engine power output. Compatible equipment models include the 330C, 336D, 345D, 349D, 950H, 966H, 972H, 980H, CT660, and CT680, covering excavators, wheel loaders, articulated trucks, generator sets, and marine propulsion units.

For optimal service life, installation should include cleaning the injector bore, replacing sealing washers and O-rings, inspecting fuel lines, checking the injector harness, and performing a leak test after installation. Operators should use clean diesel fuel with OEM-quality filters, drain water separators regularly, and monitor engine diagnostics for early detection of abnormal symptoms such as excessive smoke, poor cold start, high exhaust temperature, engine derate, or fuel rail pressure errors.
