Caterpillar original 212-3462 Diesel Engine Fuel Injector, Replacement for OEM 223-5328, compatible with C12 3176C Engines, for Caterpillar E345B Excavator, 147-0373 153-7923 original new injector

The Caterpillar 212-3462 common rail fuel injector is a precision-engineered diesel fuel injection component designed for selected Caterpillar C13 engine platforms. As a critical element of the diesel fuel delivery system, it delivers precisely metered, high-pressure fuel directly into the engine combustion chamber at electronically controlled timing to support consistent, controlled combustion. Manufactured to meet OEM specifications, it delivers stable atomization and consistent spray patterns to match the fit and performance of original Caterpillar injection components.

Constructed from high-strength alloy steel for heavy-duty industrial use, the injector features wear-resistant internal components, corrosion-resistant construction, and an industrial-grade sealing system to prevent fuel leakage and withstand harsh operating conditions. Its precision fuel metering capabilities deliver measurable operational benefits, including improved combustion efficiency, reduced fuel consumption, lower exhaust emissions, enhanced engine power output, reduced engine knocking, and extended long-term engine reliability for equipment operators.

The 212-3462 injector supports a broad range of C13 engine variants used across excavators, mining equipment, wheel loaders, heavy-duty trucks, oilfield machinery, industrial power units, marine propulsion systems, and generator sets. It adheres to OEM equivalent quality standards and includes a typical 12-month warranty, making it a dependable replacement solution for B2B equipment maintenance teams, fleet managers, and industrial parts distributors serving global Caterpillar equipment markets.
