Caterpillar original Fuel Injector Nozzle 10R-9236, 10R8988, 20R-5353 356-1373 Replacement for OEM Diesel Fuel Injector Injection Valve for Caterpillar C32 C15 C18 C27 Excavator original new injector

Built for high-output Caterpillar power, the CAT 356-1373 diesel fuel injector serves B2B buyers sourcing parts for C-Series heavy-duty engines. It is indexed under 3561373 and CA3561373, with replacement/reman references such as 20R-5353, 20R5353 and CA20R5353. Additional cross-reference records include 359-4050, 10R-0955 through 10R-0958, 10R-7228 and related numbers. Because interchange depends on serial number, fuel system calibration and application, every order should be checked against the engine SN, original injector label and CAT parts information.

As a diesel fuel injection component, the injector meters a controlled fuel charge into the combustion chamber at the required timing, atomization pattern and pressure. It supports engine operation in industrial, generator, construction and mining applications where consistent fuel delivery is essential for power, combustion stability and service reliability. The part is offered as an original-quality replacement for high-pressure CAT fuel systems, while suitability must still be confirmed by engine model and injector specification.

Marketplace and supplier data associate this number family most strongly with C32 and also with C15, C18 and related C-Series engines; C16, 3406E and 3456 appear through related 10R-0955 records. It may be requested for excavators, loaders, trucks, dozers, generator sets and other heavy equipment. Fleet maintenance teams, repair shops, reman distributors and spare-parts wholesalers should confirm ECM calibration, machine model and body number before shipment.
