Caterpillar original Diesel Fuel Injector 0R-3190 0R-8477 for 3114 3116 3126 Engine 7E-9585, Replacement for OEM 0R-3002, Fit for Excavator E320L EL200B E200B Diesel Car original new injector

For B2B procurement teams, engine rebuilders and heavy equipment fleet operators sourcing validated Caterpillar fuel system components, the 0R-3190 diesel fuel injector is an industrial-grade replacement assembly built for compatible CAT diesel engine platforms. Indexed across multiple catalog number formats to simplify cross-reference lookup, its primary OE/reman reference is 0R-3190 (alternately formatted as 0R3190), with supported cross references including 7E-8729, 0R-3002, 418-8820 and supplier-prefixed variants CA0R3190 and CA7E8729. It is sold per piece, with condition options covering new aftermarket, remanufactured, original grade and OEM-type replacement specifications.
This injector is primarily designed for CAT 3116 series diesel engines, and is widely listed in global aftermarket supplier catalogs for CAT 3114 diesel engine applications. It is commonly matched to a range of Caterpillar construction and material handling equipment, including E200B and EL200B excavators, 910E and 910F wheel loaders, and IT12B, IT14B and IT14F integrated tool carriers. Broader supplier listings may reference the CAT 3126 engine family, but compatibility for this platform is not guaranteed without formal validation.
All fitment decisions must be confirmed against the equipment parts book, original injector part number, engine model and engine serial number before purchase or installation to prevent component mismatch. For engines showing signs of injector wear, full matched-set replacement is recommended when required by engine condition or supplier guidance. It serves parts distributors, diesel repair workshops, construction fleets and equipment owners seeking a reliable cross-reference solution for CAT 3114 and 3116 fuel system maintenance.
