Remanufactured 2881993 Cummins ISX / QSX15 Holset HE551V / HE551VG Turbocharger

The 2881993 Turbocharger is a purpose-matched Holset HE551V / HE551VG assembly for Cummins ISX CM870-era applications, Cummins QSX15 applications where specified. It is built around the exact compressor, turbine, housing, and control specification associated with part number 2881993, so fitment should be confirmed from the engine serial number and original turbo tag rather than by engine family alone.

The 2881993 is an HE551V/HE551VG-family turbo associated with early Cummins ISX and QSX15 CM870 applications. This large-frame VGT provides the airflow required by the 15-litre engine while using vane control to improve response and support the engine brake. Because CM870 turbo calibrations are specific, the original part number, engine control module generation, and actuator configuration should all be confirmed before installation.

This listing is supplied as the turbocharger configuration shown. Correct installation requires clean oil feed and drain paths, a sealed charge-air and exhaust system, proper air filtration, and confirmation that the original failure did not leave debris or contamination in the engine system.

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.
