original 20R-8045 Fuel Injector Assembly for C13 C15 C18 Engine D350GC D400GC Genset Excavator Truck Diesel Injector 253-0608 20R8045 original new injector

Engineered as a direct-fit solution for the C13 inline six-cylinder, four-stroke diesel platform, this fuel injector assembly (main OE 20R-8045, cross reference 253-0608) is built to restore factory-level injection behavior on the 12.5-liter C13 and C11/C13 injector family. With 130 mm bore and 157 mm stroke configurations, turbocharged and air-to-air aftercooled variants, and industrial ratings from 287 to 400 kW, the C13 platform demands precise metering — and this injector is calibrated to meet that requirement.

Core industrial features include precision fuel metering, controlled injection timing, high atomization performance, and heavy duty construction suited to continuous industrial duty cycles. Cross references 20R8045, CA20R8045, 2530608, CA2530608, and additional service numbers 10R-1274, 10R-7236, 10R-2977, 10R-3262, 20R-8046, 20R-2437, 239-4907, 239-4908, 249-0705, 249-0708, 249-0713, 292-3666, 332-1419, and 348-4090 support wide sourcing coverage for B2B buyers. Available as single-unit or full-set replacement, the injector helps restore engine power, stabilize combustion, and reduce rough running.

Typical end users include diesel repair shops, fleet maintenance companies, engine rebuilders, construction and mining service providers, generator set service companies, and global diesel parts wholesalers. Installation should be performed by a trained technician following official torque values, with ECM injector trim coding and diagnostic reset as required.
