Engineered for demanding heavy-duty operating environments, the Fuel Injector 10R-7939 delivers precision fuel delivery for . C6.4, . C6.6, . C6.4 ACERT, . C6.6 ACERT, and Perkins 1106D-E66TA / 1106D-E70TA industrial diesel engines. This common rail injector is a direct OEM replacement and cross-references to 320-0688, 321-1080, 293-9580, 289-7500, 282-0480, 276-8280, 266-4434, 257-2500, 2645A742, 2645A753, 2645A747, 2645A708, 2645A704, 2645A703, and 2645A473, ensuring broad interchangeability across global aftermarket sourcing.
Manufactured from hardened alloy steel with precision multi-hole nozzle technology, the injector operates reliably at fuel pressures exceeding 1800 bar and up to 2000 bar. Micron-level machining tolerances, protective anti-corrosion surface treatments, and reinforced internal components deliver enhanced durability under mining, construction, marine, and industrial workloads. Every unit undergoes 100% performance testing covering injection quantity, return flow, leakage, response time, spray pattern, and solenoid resistance. Functional benefits include precise fuel metering, improved combustion efficiency, reduced fuel consumption, lower exhaust emissions, enhanced cold-start performance, improved engine responsiveness, and extended engine service life.
Typical equipment applications include . D6N, D6N XL, D6N LGP, 930H, 928HZ, 953D, IT28G, generator sets, and Perkins-powered industrial units. Installation requires a new copper washer, injector bore inspection, fuel system bleeding, and ECU coding/calibration when specified. Recommended diagnostics include return flow testing, balance testing, common rail pressure testing, ECU fault code analysis, spray pattern analysis, and solenoid resistance measurement.
