Remanufactured 3798327 Cummins ISB 6.7L Holset HE300VG / HE351VE Turbocharger

The 3798327 Turbocharger is a purpose-matched Holset HE300VG / HE351VE assembly for Cummins ISB 6.7L, Cummins QSB 6.7L medium-duty and industrial applications. It is built around the exact compressor, turbine, housing, and control specification associated with part number 3798327, so fitment should be confirmed from the engine serial number and original turbo tag rather than by engine family alone.

The 3798327 is a Cummins ISB 6.7L HE300VG/HE351VE-family short turbo calibration commonly associated with EPA13 medium-duty applications. It combines a responsive variable-nozzle turbine with a compressor sized for the ISB's air demand, supporting low-speed torque, clean transient combustion, EGR management, and exhaust braking. Fitment should be confirmed by ESN because nearby Holset numbers can share external appearance while using different vane, sensor, or housing calibrations.

This is the turbo-only version and is supplied without the electronic actuator. The existing actuator should only be reused after its condition, compatibility, and calibration are verified; a worn or incorrectly indexed actuator can cause boost, vane-position, and engine-brake faults even when the turbocharger itself is sound. Turbo Centre remanufacturing begins with complete disassembly and thorough cleaning so every critical surface can be inspected. Worn bearings, seals, and service components are replaced; shaft, wheel, housing, and vane-system condition are measured; the rotating assembly is balanced; and the completed turbo is checked for smooth operation, oil sealing, and correct control movement before shipment. This process restores the unit as a complete engineered assembly rather than simply replacing the visibly damaged component.
