original 171-9710 Diesel Engine Fuel Injector 179-6020 For 3408 3412 3408E 3412E Replacement for OEM, Cross Reference 179-9380, 138-8754, Truck original new injector

Built for the fuel-system demands of 3412-series engines, the 171-9710 fuel injector assembly is an OEM-equivalent, direct-injection diesel component identified by OEM number 171-9710 and alternate format 1719710. It is compatible with 3412, 3412B and 3412C engines, including marine, generator and industrial configurations. Its function is to deliver precisely metered diesel into the combustion chamber at high pressure: fuel enters the injector body, pressure lifts the needle, atomized fuel mixes with compressed air, and the injector closes immediately after the injection event.

Precision nozzle design, high-pressure fuel delivery and alloy-steel construction support accurate atomization, corrosion resistance and long service life. OEM fitment accuracy, flow-tested performance and industrial-grade reliability help maintain stable combustion while supporting improved combustion efficiency, reduced fuel consumption, lower emissions, increased engine power and improved cold-start performance. The assembly meets an ISO quality standard, is built for industrial service duty and carries a 12-month warranty.

Equipment applications include mining trucks and excavators, industrial generator sets, marine propulsion systems, oilfield power units, industrial compressors, construction equipment and stationary power plants. For maintenance programs, the injector offers OEM fitment, stable performance and cost-effective maintenance. Protect service life by using clean diesel, replacing fuel filters on schedule and avoiding contaminated fuel; installation should follow the service manual, with sealing components replaced and torque applied to OEM specification.
