Cummins 6375805 Turbocharger Assembly HE200WG

The Cummins 6375805 turbocharger features the Holset HE200WG wastegated compressor housing design, calibrated specifically for the QSB6.7 (CPL426) engine platform. It utilizes a journal bearing rotating assembly with a 54mm compressor wheel inducer and 60mm turbine wheel exducer, optimized for mid-range torque response and emissions compliance. Constructed from high-nickel alloy turbine housing (Ni-Resist) and aluminum compressor housing, the unit withstands exhaust gas temperatures up to 950°C. The integrated wastegate actuator is pneumatically controlled, calibrated to 1.2 bar opening pressure. This assembly supersedes part number 6375804 and interchanges with Holset service model 3590044. Installation requires new gasket kit 3802357 and torque-to-yield fasteners per Cummins service manual Bulletin 4021471.
