Holset 2881751 Turbocharger HX35W Assembly

The Holset HX35W turbocharger assembly bearing part number 2881751 is engineered for Cummins 6BTAA 5.9L medium-duty diesel engines. This unit features a wastegate actuator for precise boost control across the operating range. The compressor and turbine wheels are matched specifically for the 6BTAA torque curve, delivering reliable low-end response and high-altitude compensation. Constructed with a forged compressor wheel and high-nickel turbine housing, the CHRA utilizes a full-floating bronze bearing system with piston ring seals. The assembly supersedes part numbers 2837686 and 2837731. It is a direct bolt-on replacement for factory-equipped turbochargers on Dongfeng Tianlong Flagship tractors and various construction equipment utilizing the Cummins 6BTAA powerplant. Installation requires new oil feed line, gaskets, and torque-to-yield fasteners per Cummins service manual specifications.
