Perkins original Perkins 10R-7223 fuel injector replacement for OEM diesel engine spare part original new injector

Engineered as a direct replacement for the Perkins C9 platform, the 10R-7223 electronic unit injector delivers precision fuel metering and consistent spray patterns across demanding duty cycles. It is fully interchangeable with 326-4701, 326-4702, and 326-4703, allowing fleet operators to consolidate part numbers without compromising on injection performance or combustion efficiency. The multi-hole nozzle geometry and hardened alloy steel construction ensure superior atomization, stable rail pressure response, and long-term wear resistance in high-load environments.

This injector is validated for use in Perkins 330D, 336D, and 345D excavators, 966H, 972H, and 980H wheel loaders, 140M and 160M motor graders, as well as generator sets, marine propulsion engines, and industrial power units. Its robust corrosion-protected housing and OEM equivalent quality standard make it equally suited for construction sites, mining operations, agricultural machinery, and power generation applications where uptime and fuel economy are critical operational priorities.

Before installation, operators should inspect the injector bore, replace all O-rings and sealing washers, and bleed the fuel system to remove air pockets. After fitting, verify fuel pressure and confirm individual injector balance rates against manufacturer specifications. Use only clean, high-quality diesel, service fuel filters routinely, and drain water separators at scheduled intervals to maximize service life, supported by a 12-month warranty and global aftermarket availability.
