Caterpillar original Fuel Injector 211-0565 10R-7228 Replacement for OEM 211-3028, for heavy duty diesel engine application, 0R-9803 for C15 C16 C18 3406E Truck Engines original new injector

Tailored for industrial Caterpillar diesel engine aftermarket and replacement supply chains, the 211-0565 fuel injector is a heavy-duty injection assembly indexed for global B2B parts sourcing. Searchable via format variations 2110565 and 211 0565, it is primarily associated with CAT C15 and C18 engine platforms, with preliminary supplier listings also linking it to C13 and 3406E engine families. It is designed for diesel fuel systems, and caters to professional buyers including engine rebuilders, diesel workshops, fleet maintenance teams, parts wholesalers and export distributors.

The component is mapped to a tiered cross-reference database to support flexible parts inquiry and matching. High-confidence replacement numbers include 211-3028 and 10R-7228, while medium-confidence market references cover 253-0618 and 10R-7231; extended injector-family search numbers are available for broader sourcing but require additional fitment validation. It is commonly used in excavators, heavy-duty trucks, generators, marine power units and construction machinery, serving sectors spanning construction, mining, industrial power, oil & gas, agriculture and marine operations.

Given that CAT injector compatibility is strictly tied to engine arrangement, serial number and fuel system configuration, no cross reference qualifies as a guaranteed direct replacement without official verification. Before ordering, buyers must confirm the existing injector part number, engine model, engine serial number, machine model, ECM/fuel system setup and injector body marking, and validate fitment via the official Cat parts lookup platform or a local authorized Caterpillar dealer.
