Perkins original Perkins Common Rail Fuel Injector Assembly 174-7527 Replacement for 3412 3408E 3412E C15 AD45 Diesel Engine  original new injector

Engineered for the demanding requirements of Perkins 3412 series diesel engines, the 174-7527 fuel injector delivers precision fuel atomization that optimizes combustion efficiency across a wide range of heavy-duty applications. Constructed from industrial-grade alloy materials, this injector is built to withstand extreme thermal and vibration conditions commonly encountered in construction, mining, power generation, marine, and oil and gas operations. Its OE-compliant design ensures a direct fit and consistent performance matching original specifications for the 3412, 3412B, and 3412C engine variants.

The high-pressure fuel delivery system is specifically engineered to resist carbon build-up, maintaining stable injection performance over extended service intervals. By promoting more complete fuel combustion, this injector helps reduce harmful emissions while improving overall fuel economy. The robust internal components and precision-machined nozzle assembly provide reliable fuel metering under high-load conditions, making it suitable for generator sets, industrial equipment, agricultural machinery, and heavy transportation applications where consistent engine performance is critical.

For optimal service life, fuel filters should be cleaned regularly to prevent clogging, and extended idling should be avoided to minimize carbon deposit formation. Periodic inspection is recommended every 500 hours of operation, and only OEM-recommended lubricants and fuels should be used. If spray pattern degradation, hard starting, excessive smoke, or poor acceleration occurs, the injector should be inspected, cleaned, or replaced to restore proper engine function. Compatible cross references include 9X-1234, 123-4567, 3412B, 3412C, and 45–50.
