The Caterpillar 3412 Series Fuel Injector 20R-4147 is an OEM-grade component engineered for demanding heavy-duty diesel applications. Built from high-grade alloy steel, this injector delivers consistent fuel atomization through precision-machined single or multi-orifice nozzle tips, maintaining stable spray patterns at an operating pressure of 1200–1600 bar. Its robust mechanical and common rail design ensures reliable metering across a wide range of load conditions, while corrosion-resistant internal components extend service life in harsh operating environments such as mining sites, marine vessels, and remote power generation stations.
Designed as a direct replacement for OE numbers 10R-7222, 331-8770, and 0R-4171, the 20R-4147 injector is fully compatible with CAT 3412, 3412B, and 3412C engines. It supports standard industrial diesel fuels as well as biodiesel blends, and its vertical or inline installation orientation allows straightforward integration into existing engine configurations. Each unit is manufactured to meet Caterpillar OEM standards and global emissions requirements, providing dependable performance for earth movers, bulldozers, excavators, tugboats, cargo ships, diesel generators, compressors, loaders, graders, and large-scale agricultural machinery.
For optimal longevity, operators should clean fuel filters regularly, inspect the spray pattern and nozzle wear periodically, and replace the injector every 20,000–30,000 operating hours. Installation requires tightening mounting bolts to 35–40 Nm and pre-lubricating with clean diesel oil before fitting. A diagnostic bench check of the spray pattern prior to engine installation is recommended. Backed by a 12-month industrial warranty, this injector is available for global distribution across the US, EU, APAC, MENA, and LATAM regions.
