Perkins original Perkins original Perkins 350-7555 Diesel Fuel Injector for C10 C12 Engine, Excavator Construction Machinery Parts Replacement for OEM new injector original new original new injector

The Perkins 350-7555 fuel injector is engineered for Perkins C10 and C12 diesel engines, delivering precise fuel metering and efficient atomization across demanding industrial applications. It is designed to withstand high temperatures, vibration, variable fuel quality, and long operating hours typical of heavy-duty excavators, loaders, articulated trucks, mining machines, generators, and marine equipment. Built to support power recovery and fuel economy, this injector GP-fuel assembly provides reliable performance under continuous-duty cycles and heavy load conditions, while remaining compatible with modern low-sulfur and low-lubricity diesel fuels.

This replacement injector cross-references with 20R-0056 and CA3507555, fitting Perkins 345B, 365B, 725, 730, 972G II, R1600G, and W345B II machinery, as well as Challenger MT-series equipment. It is suitable for 3176 and 3196 engines listed in certain aftermarket databases. Each unit is tested for wear life, fuel economy, and overall performance, meeting industrial durability standards required for engine repair and rebuild operations in field and workshop environments.

Proper maintenance includes using clean diesel fuel, replacing fuel filters on schedule, draining the water separator, and keeping the fuel tank clean. Injectors should be stored in sealed packaging and never dropped, opened, modified, or exposed to dust. During installation, replace all seals and O-rings and follow official Perkins service manual torque values. After replacement, monitor engine oil condition, exhaust smoke, idle quality, and diagnostic codes. Common failure signs such as hard starting, rough idle, black smoke, power loss, high fuel consumption, and excessive return fuel can be diagnosed through fuel pressure testing, return-flow testing, cylinder cut-out testing, and ECM code reading.
