Perkins original Perkins 350-7555 Engine Fuel Injector For C10 C12 Excavator Replacement for OEM new injector original new injector

The Perkins C12 C10 Diesel Fuel Injector 350-7555 is a direct replacement unit engineered for Perkins C12 and C10 series diesel engines widely used in heavy construction, mining, and industrial power applications. It is designed to deliver precise fuel quantity into the combustion chamber at the correct timing, supporting stable engine power output, reduced exhaust smoke, smoother idle quality, and improved fuel economy under demanding operating conditions. The injector features wear-resistant internal components, robust sealing, and consistent atomization performance, which together help recover lost power and reduce abnormal combustion in aging engines.

This replacement injector is compatible with multiple authorized cross reference numbers including 20R-0056, 10R-1003, OR-9530, 170-5252, 203-7685, and 317-5278, allowing flexible use across Perkins machine platforms such as 345B, 345B II, 345B II MH, 345B L, 365B, 365B II, 365B L, 725, 972G II, R1600G, and CPT372. Each unit is factory tested for spray pattern, flow rate, and sealing integrity before shipment, ensuring reliable installation in engine overhaul projects, scheduled maintenance, and field replacement. The direct-fit design matches original connector geometry and mounting dimensions for convenient installation without additional modification.

Proper maintenance extends injector service life significantly. Operators are advised to use clean diesel fuel, replace fuel filters on schedule, drain the water separator regularly, and keep the fuel tank free from contamination. Routine diagnostic checks including fuel pressure testing, injector return flow testing, cylinder cut-out testing, and compression testing are recommended when symptoms such as hard starting, rough idle, black or white smoke, misfire, excessive fuel consumption, or diesel knock appear. Spare injectors should be stored in sealed, dry, and clean packaging to preserve internal precision and prevent premature failure.
