Caterpillar original Fuel Injector 370-7282 for C6.6 C7.1 Diesel Engine, Replacement for OEM 20R-2478, Cross Reference 295050-0401 for CAT320E Excavator Construction Machine original new injector

Procurement teams, engine rebuilders and heavy equipment maintenance contractors can rely on the genuine-quality CAT 370-7282 diesel fuel injector, purpose-built for Caterpillar 3512B engine platforms. As a core diesel fuel injection system component, it performs five core functions: precise fuel metering, injection timing control, fuel atomization, consistent spray pattern formation, and combustion optimization. These capabilities improve fuel economy, power output, engine response, emissions performance, cold-start capability and long-term engine reliability under sustained heavy-duty operating loads.

This injector is mapped to a full set of industry-recognized part numbers to support cross-system sourcing, including OEM alternative 3707282, reman numbers 20R-2478 and 20R2478, cross references T409982 and T4-09982, supplier reference numbers 295050-0401, 2950500401, 295050-0400 and 2950500400, plus aftermarket number CA3707282. It fits 3512B engines deployed across power generation, marine, mining, oil & gas and construction sectors, covering generator sets, work vessels, mining stations, drilling power units and industrial pumping systems.

Each 370-7282 injector is manufactured with high-precision machining to ensure dimensional accuracy and repeatable injection performance. Hardened critical internal surfaces deliver wear resistance for high-pressure fuel environments, specialized coatings provide corrosion and contamination protection, and the unit features high-temperature tolerance for continuous industrial operation. Its precision nozzle delivers a stable uniform spray pattern for consistent combustion, and the unit is engineered for extended service intervals under heavy workloads.
