Caterpillar original Fuel Injector Cross Reference 20R-8071, 241-3238, 263-8218, 20R-8056 Replacement for C7 Injector Engine for Construction Machinery Excavator original new injector

Tailored for heavy-duty Caterpillar C7 engine maintenance and overhaul programs, the 20R-8056 is a professional-grade HEUI diesel fuel injector designed for the brand’s C7, C7 ACERT and select C7.2 engine families. The 7.25L inline-six C7 platform powers a wide range of on-highway and off-highway assets, including excavators, loaders, medium-duty trucks, buses, industrial power units and generators, with rated outputs ranging from 168–224 bkW at 1800–2200 rpm. Each C7 engine typically requires 6 injectors mounted in the cylinder head injector bores.

This injector operates within Caterpillar’s Hydraulic Electronic Unit Injector (HEUI) architecture, which uses high-pressure engine oil to hydraulically actuate injection, while the engine ECM electronically controls injection timing and fuel delivery volume. Its core function is to precisely meter, atomize and inject diesel fuel directly into the combustion chamber to support efficient, stable engine operation, matching the design specifications of original C7 injection system components.

Multiple condition options are available to suit diverse repair, fleet and reseller budget requirements, including new replacement, remanufactured, OEM-type and aftermarket variants, with flexible packaging options spanning neutral boxes, branded packaging, export cartons and custom customer-labeled packaging. As C7 injector compatibility is highly configuration-specific, B2B buyers must verify parameters including engine serial number, arrangement number, injector code and ECM calibration before ordering, with both single units and 6-piece engine sets offered.
