The Caterpillar CAT 177-4753 is an industrial-grade HEUI diesel fuel injector assembly developed for professional aftermarket service of Caterpillar 3126 series diesel engines, covering 3126, 3126B and 3126E models. It is identified by multiple part number formats, with 177-4753 as the core OE number and 1774753 as its compact equivalent, plus verified cross-reference numbers to support sourcing and inquiry matching. Classified as both a fuel injection valve and complete injector assembly, it is purpose-built for targeted replacement applications.
This injector is engineered to operate with the Caterpillar HEUI hydraulically electronically controlled fuel system, where the engine ECM regulates fuel delivery and high-pressure engine oil drives injection events. The system includes a high-pressure oil supply pump and injector actuation pressure control valve, and is designed to optimize engine starting, warm-up performance, emissions, noise levels, fuel economy and overall drivability. A standard inline 6-cylinder 3126 engine requires six matching units for a full injector service.
It caters to a broad spectrum of B2B buyers, including diesel parts suppliers, engine rebuilders, fleet maintenance firms, repair workshops, heavy equipment service providers, marine service companies, truck parts distributors and global aftermarket exporters. To ensure correct fitment, buyers must verify compatibility via the original injector number, engine serial number, engine arrangement number, injector code, connector type and physical comparison before confirming orders.
