original 20R-5075 Fuel Injector 456-3544 460-8213 20R-5079 for C9.3 336E 336F Excavator Truck Replacement  original new injector

Engineered specifically for the C9.3 engine platform, the 20R-5075 fuel injector delivers precise fuel metering within an electronically controlled high pressure common rail system operating at 1800-2200 Bar. The component integrates seamlessly with the C9.3 fuel-cooled architecture and utilizes heat treated alloy steel construction to maintain micron-level machining tolerance under continuous heavy-load operation. Tier 3 and Tier 4 compatibility ensures the injector meets current emissions benchmarks while preserving the original combustion characteristics of the C9.3 power unit.

The 20R-5075 is validated across a wide range of C9.3-powered applications, including 320, 323, 325, 326, and 330 series excavators, 950, 950GC, 962, and 966 wheel loaders, and 140, 150, and 160 motor graders. Beyond construction equipment, the injector supports generator sets, pump units, compressor packages, power modules, mining machinery, and marine auxiliary installations. Cross references 20R5075, 456-3509, 456-3493, 171-9704, 196-1401, 222-5966, 324-5467, and 364-8024 allow flexible interchange within the C9.3 service network.

Built to OEM performance standards, this injector assembly provides corrosion resistance against water contamination, sulfur exposure, and fuel degradation commonly encountered in mining, quarry, construction, power generation, and marine environments. Superior combustion performance translates into maximum fuel efficiency, reduced emissions, and increased engine reliability. Available in new, OEM, and reman configurations, the 20R-5075 extends service life and supports severe-duty industrial applications requiring consistent C9.3 fuel delivery performance.
