The Perkins 3412 Series Fuel Injector 104-3377 is an OEM-quality mechanical diesel fuel injector engineered for the Perkins 3412, 3412B, and 3412C diesel engines delivering 425-500 HP, 400-480 HP, and 450 HP respectively. Built with high-grade steel alloy components, it withstands extreme operating conditions with a working temperature range of -40°C to 120°C and a service life of 5,000-10,000 hours, making it suitable for excavators, generator sets, industrial pumps, and marine propulsion systems.
This injector is designed for optimal fuel atomization through a multi-hole precision spray pattern, supporting fuel pressures between 1500-2500 bar to ensure efficient combustion. It is compatible with multiple OEM and cross-reference numbers, including 104-3377, 0R-43377, 1043377A, 317-43377, 1043377B, and 8N-43377, allowing seamless integration into existing fuel systems. Each unit is precision-tested for consistent performance across a wide range of operating conditions.
Installation requires torque settings of 35-40 Nm for mounting bolts, proper alignment with the fuel rail and engine cylinder, and the use of OEM-approved gaskets and seals to prevent overtightening damage. Regular maintenance every 500 hours, including inspection of seals, spray pattern diagnostics, and use of certified diesel fuel meeting ASTM D975 or equivalent, helps maintain injector reliability and engine efficiency in demanding industrial environments.
