Perkins original Perkins 171-9710 HEUI Fuel Injector 138-8754 179-6020 0R-9348 174-7527 for 3408E 3412E Engine Spare Parts original new injector

Engineered as a direct OEM equivalent replacement, the Perkins 171-9710 fuel injector assembly is purpose-built for the Perkins 3412, 3412B, and 3412C diesel engine platforms. It is designed to integrate seamlessly with the Perkins mechanical direct injection fuel system, preserving factory fuel delivery characteristics without requiring system modifications. The injector meets OEM pressure specifications and is manufactured to original equipment dimensional tolerances, ensuring accurate fitment across all supported engine variants.

The 171-9710 injector features a precision-machined nozzle that delivers high-pressure fuel atomization for optimized combustion efficiency, improved power output, and reduced fuel consumption. Constructed from hardened steel alloy with corrosion-resistant properties, each unit is flow-tested to confirm consistent performance under heavy-duty operating conditions. Its robust design supports reliable operation in severe industrial environments where sustained performance is critical.

This injector is widely specified for mining trucks, excavators, industrial generator sets, marine propulsion systems, oilfield power units, industrial compressors, construction equipment, and stationary power plants. Routine maintenance practices such as using clean diesel fuel, replacing fuel filters on schedule, and monitoring injector performance will extend service life. If symptoms such as hard starting, excessive smoke, poor fuel economy, engine vibration, power loss, or injector leakage appear, replacement of the injector assembly is recommended to restore engine performance.
