original 7E-8952 Diesel Engine Fuel Injector for 3116 Engine 200B 320B 322B 325B 446B Excavator Parts Fuel Injector Pump Replacement for OEM 0R-8467 original new injector

Engineered for demanding fleet operations, the 7E-8952 diesel fuel injector assembly delivers OEM-equivalent performance for 3116, 3116TA, and 3116DITA inline six-cylinder engines. Built to fit 6.6L water-cooled mechanical direct injection fuel systems with power outputs ranging from 170-350 HP, this injector is a direct crossover replacement for OE references 0R-8471, 0R-3006, 4P-2995, 0R-8465, 0R-4374, 127-8205, 127-8207, 127-8209, 127-8213, 127-8222, 127-8225, 127-8228, and 162-0218, providing procurement flexibility for global aftermarket buyers.

Manufactured to OEM standards, each unit features precision fuel metering, an advanced spray pattern design, and hardened internal components engineered for high wear resistance and corrosion protection. Full factory testing ensures consistent performance, improved combustion efficiency, reduced emissions, enhanced fuel economy, and stable idle behavior. The injector is designed for extended service life under continuous-duty conditions typical of excavators, wheel loaders, motor graders, marine vessels, generator sets, industrial pumps, and agricultural machinery, making it a reliable component for construction, mining, marine, and power generation applications.

Installation follows standard OEM procedures: shut down the engine, depressurize the fuel system, remove the old injector, clean the injector bore, fit new seals, torque to specification, bleed the fuel system, and verify leak-free operation. Recommended maintenance includes using high-quality diesel fuel, regular filter replacement, avoiding water contamination, and periodic injector testing to identify symptoms such as difficult starting, rough idle, power reduction, or excessive exhaust smoke.
