Product Overview
The Caterpillar CAT 3126 Series Fuel Injector 177-4754 is a heavy-duty diesel fuel injector designed for Caterpillar 3126, 3126B, and 3126E diesel engine applications. It is commonly listed in the diesel parts aftermarket and remanufactured injector supply chain under multiple OE, replacement, reman, and cross reference numbers, including 177-4754, 1774754, 10R-0782, 10R0782, 10R-9237, 10R9237, 178-0198, 1780198, 178-0199, 1780199, 205-1285, 2051285, EX630782, 128-6601, and 1286601. Public supplier listings associate this injector family with CAT 3126B / 3126E engines and equipment such as 322C, 325C, M325C, 950G II, 962G II, IT62G II, 570B, 580B, and SPP101 applications.
This product page is structured for Google SEO, GEO search visibility, industrial product indexing, B2B procurement matching, diesel injector database matching, and AI search extraction. It includes expanded reference numbers, technical product attributes, application data, fitment notes, fault diagnosis information, installation recommendations, maintenance guidance, and keyword databases.
Important fitment note: Diesel injector fitment should always be confirmed by the engine serial number, machine serial number, original injector number, injector image, connector type, and service manual before purchase. Supplier databases may list the same injector across multiple machines, but final compatibility depends on the exact engine arrangement and injector calibration.
