original 174-7526 Diesel Fuel Injector for 3408E 3412 C18 Engine Truck Injector Nozzle Assembly Replacement OEM 1747526 173-9267 232-1173 original new injector

Engineered as a direct-fit replacement solution for the 3126 series diesel platform, this heavy-duty fuel injector assembly (OE 174-7526, cross-referenced to 20R-0758, 0R-0758, CA1747526 and INJ1747526) delivers precise metering and atomization required by modern high-pressure direct-injection fuel systems. Each unit is manufactured from high strength alloy steel, machined to OEM tolerances, and 100% factory tested on calibrated benches to verify flow rate, spray pattern, response time, and leak tightness before packaging.

Designed for 3126, 3126B and 3126E engines used in excavators, wheel loaders, backhoe loaders, heavy trucks, commercial buses, generator sets, marine propulsion units, agricultural tractors and industrial compressors, this injector supports optimized combustion, lower emissions and reduced fuel consumption. Its precision nozzle geometry, corrosion-resistant internal components and long service life make it suitable for continuous-duty industrial power units and demanding off-highway operating conditions. The product is available in New or Reman condition with a 12-month warranty and neutral or customized packaging for OEM, aftermarket and distributor programs.

Recommended maintenance includes using OEM-grade fuel filters, preventing water contamination, monitoring fuel pressure and performing periodic injector testing. Installation requires cleaning the injector seat, replacing the sealing washer, applying specified torque, priming the fuel system and verifying injector balance with a diagnostic tool to prevent leaks, sticking, poor atomization and combustion imbalance.
