Details
Product Overview The 155-8723 / 1558723 Caterpillar 3126 series fuel injector is an industrial-grade HEUI diesel fuel injector designed for Caterpillar 3126, 3126B, and 3126E diesel engine applications. It is used in heavy-duty diesel engine systems where precise fuel metering, stable atomization, fast response, and reliable combustion performance are required. This injector is commonly searched in the global aftermarket under multiple OE numbers, reman numbers, replacement numbers, catalog numbers, and supplier cross-reference numbers, including 155-8723, 1558723, 20R-5392, 169-7408, 178-6342, 111-7916, 0R-9350, 173-9272, 196-1401, 218-4109, 128-6601, 4CR0197, 232-1167, 222-5972, 2C0273, 153-5938, 155-1819, 20R-0758, and 232-1171. Public supplier databases list many of these numbers in relation to Caterpillar 3126 fuel injector families, but final confirmation should always be made by engine serial number, injector code, original part number, and application model before ordering. This product is suitable for professional diesel repair shops, engine rebuilders, equipment fleets, construction machinery suppliers, remanufacturing companies, and global aftermarket distributors.

Working Principle of the Caterpillar 3126 HEUI Injector

The Caterpillar 3126 series uses a HEUI fuel injection system, which means Hydraulic Electronic Unit Injection. Unlike a conventional mechanical injector, a HEUI injector uses high-pressure engine oil as hydraulic force to intensify and control diesel fuel injection. The engine control module controls injection timing and duration electronically, while hydraulic oil pressure provides the force needed for injection.
