Holset 5321617 Turbocharger Kit Assembly

Technical engineering specifications and operating parameters for the Holset 5321617 turbocharger kit, engineered for the Cummins QSK60 60.2-liter V16 diesel engine platform. This kit serves as a direct OEM replacement for Cummins part numbers 5321617, 3768267, 5352714, and 4972818, ensuring precise fitment and performance parity with original equipment. The turbocharger assembly features a water-cooled center housing with full-floating journal bearings, lubricated by engine oil pressure, and integrates an electronic wastegate actuator for precise boost control under the Modular Common Rail (MCR) fuel system. Designed for the high-mass airflow demands of the QSK60's 2,000 to 3,000 horsepower rating range, the compressor and turbine wheels are optimized for the V16 cylinder configuration's firing order and exhaust pulse characteristics. Primary applications include the Northern Heavy Industries NTE240 electric-drive mining truck, stationary power generation generator sets (QSK60-G3, G4, G6, G7, G12), marine propulsion, and oil & gas drilling equipment. The kit includes the turbocharger cartridge assembly (CHRA), compressor housing, turbine housing, actuator, and necessary installation gaskets and hardware. Manufactured to Holset OEM standards for durability in continuous heavy-duty cycles, including high-altitude and high-ambient temperature environments. Cross-references include aftermarket numbers 2881993, 5357028, and 4955916.
