original 174-7527 Diesel Fuel Injector Assembly for 3126 C7 3406E 3408 3412 C15 C18 Engine Replacement for OEM 173-9267 173-9268 174-7526 original new injector

Engineered for demanding heavy-duty operations, this 3126 Series Diesel Fuel Injector (OE 174-7527 / 1747527) is a precision-manufactured component designed for the HEUI (Hydraulically Actuated Electronically Controlled Unit Injector) fuel system. Fully interchangeable with 20R-0758, 174-7526, 232-1175, 232-1183, 232-1173, 232-1168, 10R-1262, and 138-8756, this injector is a direct replacement solution for 3126, 3126B, and 3126E engine platforms operating on diesel fuel across industrial and commercial fleets worldwide.

Manufactured from hardened alloy steel with precision-ground components, heat-treated internal parts, and corrosion-resistant coatings, the 174-7527 injector delivers OEM-level calibration, high injection accuracy, and superior fuel atomization. These engineering advantages translate into lower fuel consumption, reduced smoke emissions, improved cold-starting performance, and enhanced service life. Every unit undergoes rigorous quality control including flow testing, spray pattern testing, solenoid testing, leak testing, pressure testing, and durability verification to ensure consistent field performance.

Widely deployed across North American mining and municipal fleets, European agricultural machinery, Asia-Pacific port and construction equipment, Middle Eastern oil & gas machinery, African generator installations, and Latin American transport fleets. Recommended installation procedure includes verifying part numbers, replacing sealing components, lubricating O-rings, torquing to specification, and priming the fuel system. Preventive maintenance with OEM-grade filters and clean diesel fuel ensures maximum injector service life and reliable engine operation.
