Caterpillar original  20R-8063 387-9434 267-9715 Common Rail Diesel Fuel Injector For C9 Engine D6R D6T D7R Excavator Dozer 511 2290 new injector original new injector

The CAT C9 Fuel Injector 20R-8063 is engineered as a direct OEM replacement for Caterpillar C9 and C9 ACERT engines, delivering precise common rail fuel injection across demanding heavy-duty applications. Built with hardened internal components and precision nozzle technology, this injector maintains strict OEM manufacturing tolerances while supporting high pressure diesel injection for consistent performance.

Designed to integrate seamlessly with CAT 330D, 336D, and 973D equipment, the 20R-8063 injector also serves CAT C9 generator sets, marine propulsion engines, industrial power modules, and agricultural machinery. Each unit is flow calibration tested to ensure accurate fuel metering, improved combustion efficiency, reduced fuel consumption, and lower particulate emissions. The result is enhanced cold start capability, stable idle operation, and reliable power output across extended duty cycles in construction, mining, and power generation environments.

Constructed from corrosion resistant materials and assembled to industrial reliability standards, the 20R-8063 replacement injector offers durable service life under harsh operating conditions. Cross referenced with 10R-7675 and 328-2577, it provides a dependable alternative for fleet maintenance and engine overhaul programs. Proper installation requires clean fuel system preparation, replacement of injector seals, adherence to Caterpillar torque specifications, injector coding, and leak testing to verify ECM diagnostics for optimal long-term operation.
