Caterpillar original Excavator Engineering Machinery Fuel Injector 212-3463 20R-0056 for C12 C15 C18 3512 Engine Parts, Cross Reference 212-3460, Replacement for OEM 10R-0967 original new injector

The Caterpillar 20R-0056 fuel injector is an OEM-quality, factory-remanufactured diesel injection component engineered for CAT C10 and C12 engine platforms, including C12 ATAAC, C12 Marine, and C12 Generator variants, as well as 3176 and 3196 industrial engines. As the core metering device of the high-pressure fuel system, it atomizes diesel into microscopic droplets at precisely timed intervals, directly determining combustion efficiency, horsepower output, emissions levels, fuel economy, and overall engine reliability under continuous heavy-duty operation.

Every unit is manufactured to Caterpillar OEM and Reman specifications with strict dimensional tolerances. Hardened steel, wear-resistant components, and corrosion-resistant surface treatments withstand extreme temperatures, fluctuating fuel pressures, and fuel contaminants. Optimized nozzle geometry delivers superior atomization and stable fuel flow across all engine loads and speeds, producing more complete combustion, increased power, lower particulate emissions, reduced fuel consumption, and faster engine response—extending service life and protecting long-term engine health.

This injector interchanges with 350-7555, 170-5252, 203-7685, and 10R-1268, simplifying sourcing for rebuilders and fleet maintenance teams worldwide. Proven applications include CAT 345B, 345B II, 365B, and 365B II excavators, 725 and 730 articulated trucks, 972G II wheel loaders, R1600G mining machines, and MT835–MT865 agricultural equipment, plus generator sets and marine installations. For distributors, repair shops, and equipment operators seeking dependable C10/C12 fuel system components, the 20R-0056 offers genuine fit, consistent performance, and broad cross-reference coverage.
