Caterpillar original Fuel Injector 387-9436 20R-8062 10R-4844 Replacement for OEM 459-8473 for C9 C7 C-9 Engine Excavator Truck, for heavy duty diesel engine application original new injector

Built for the demanding requirements of the Caterpillar C9 engine platform, the CAT 20R-8062 fuel injector is a precision-engineered electronic high-pressure common rail diesel component for global heavy-duty equipment fleets. As the final critical part of the fuel delivery system, it meters precise diesel volumes into the combustion chamber at exact timing, pressure and spray patterns, directly supporting stable power output, optimized fuel economy, effective emission control, reliable cold starts and consistent combustion efficiency across all operating loads. It fits both standard C9 and C9 ACERT turbocharged diesel variants.

Manufactured with high-strength alloys, advanced machining and precision nozzle calibration, the 20R-8062 meets or exceeds OEM performance requirements under strict quality control. Verified benefits include higher combustion efficiency, lower fuel consumption, increased horsepower, reduced emissions and particulate output, sharper throttle response, stable idle and improved cold starting. These advantages extend service life, cut unplanned downtime, reduce maintenance costs and boost overall equipment productivity for industrial operators.

This injector supports C9-powered equipment across construction, mining, marine, power generation, industrial, oil & gas and heavy-duty transport sectors, including Caterpillar 330D/336D excavators, 966H/972H wheel loaders, 140M motor graders, dozers, generator sets and marine propulsion systems. Cross-referenced with 326-1641 and 3261641 for easy procurement verification, it requires compatibility confirmation via engine (ESN) and equipment (PIN) serial numbers, with professional installation following pressure relief and seat cleaning protocols recommended.
