Caterpillar original 223-5328 Fuel Injector Assembly for C10 C12 Excavator Loader Diesel Engine 212-3468 350-7555 20R-0056 original new injector

The Caterpillar CAT C12 Fuel Injector 223-5328 is engineered as an OEM-level replacement component for the electronic unit injection system used across the Caterpillar C12 engine platform. Designed with advanced nozzle technology, this injector delivers high-pressure fuel atomization that supports clean combustion, stable idle quality, and consistent power output under demanding operating conditions. Manufacturing precision in line with OEM standards ensures direct-fit compatibility with truck, industrial, marine, generator, and power unit configurations of the C12 engine.

Built for heavy-duty service environments, the 2235328 injector incorporates superior wear-resistant materials and enhanced corrosion protection to extend service intervals and reduce unscheduled downtime. Each unit undergoes 100% flow and pressure testing prior to shipment, confirming that performance characteristics meet or exceed factory specifications. The assembly is suitable for heavy-duty trucks, construction machinery, mining equipment, marine propulsion systems, industrial diesel power units, and generator sets operating in transportation, construction, mining, marine, power generation, and industrial manufacturing sectors.

Flexible packaging options including Neutral, OEM, and Customized formats support a wide range of distribution channels, while cross-reference compatibility with part numbers 10R0957, 10R1273, 20R2057, 10R0957RX, 20R2057RX, and CAT2235328 broadens application coverage across the Caterpillar product range. A standard 12-month warranty backs the product, and adherence to OEM maintenance schedules — including the use of clean diesel, regular fuel filter replacement, and periodic injector balance testing — helps maintain long-term reliability and protect overall fuel system integrity.
