Caterpillar original Engine Fuel Injector 20R-8066 10R-7225 for Caterpillar C7 Engine, Replacement for OEM 328-2585, with Cross Reference 295-1408 Fit for Excavator E320D E324D L original new injector

For B2B buyers sourcing heavy-duty fuel system components for Caterpillar C7 engine platforms, the 20R-8066 fuel injector assembly is a purpose-built diesel injection solution. Classified as a Cat® fuel injector group, it is engineered to precisely meter, atomize, and deliver diesel fuel to the combustion chamber to support stable combustion efficiency and engine performance. It serves C7 variants including C7 ACERT, industrial, and construction configurations, with use cases across excavators, wheel loaders, material handlers, and industrial power units.

The 20R-8066 (alternately written 20R8066) has a validated cross-reference list including 20R-9079, 387-9427, 263-8218, 268-1835, 295-1411, 10R-7225, and 557-7627. Additional supplier-listed part numbers and supply chain codes exist but require verification against the original injector number before interchange. All fitment must be confirmed via engine serial number, injector code, and machine model prior to ordering, as C7 platforms have varying emissions and fuel system calibrations.

The injector is available in multiple supplier-dependent condition options: new aftermarket, remanufactured, rebuilt, and OEM-quality replacement, all aligned with Caterpillar fit specifications. To ensure uniform fuel delivery and consistent performance, suppliers recommend replacing the full injector set rather than mixing units with differing flow or atomization properties. Buyers may consult a Cat dealer to confirm compatibility with their exact equipment configuration.
