Holset 5351156 HE400WG Turbocharger Assembly

The Holset HE400WG is a single-stage, wastegated turbocharger designed for heavy-duty diesel applications. It features a 60 mm compressor wheel inducer diameter and a 16 cm2 turbine housing A/R ratio, optimized for high-flow capability and efficient spool response. The unit integrates a pneumatic wastegate actuator calibrated to a 1.7 bar pressure setting for precise boost control. Compressor outlet orientation is configured at 205 degrees with turbine inlet at 360 degrees for specific engine packaging requirements. The center housing rotating assembly (CHRA) utilizes a full-floating bearing system lubricated and cooled by engine oil, with turbine wheel constructed from nickel-based superalloy for high-temperature durability. This assembly serves as a direct OEM replacement for multiple part numbers across Volvo Construction Equipment, Volvo Trucks, and Cummins engine platforms. Primary OEM cross-references include Volvo 3792723, 3792724, 21831660 and Cummins 3770379, 4051033. It is engineered for fitment on Volvo MD11 and MD9 engines powering A25F and A35F articulated dump trucks, as well as Cummins ISL, QSC8.3, and L375 8.9L engines in bus and medium-duty vocational applications. Interchange references include TurboMaster 5351156 and Denco 4031212h.
