Remanufactured 2881994 Cummins ISX / QSX15 Holset HE551V / HE551VG Turbocharger

The 2881994 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 2881994, so fitment should be confirmed from the engine serial number and original turbo tag rather than by engine family alone.

The 2881994 HE551V/HE551VG is a CM870-era Cummins ISX/QSX15 variable-geometry turbocharger. Its robust turbine and compressor system is sized for sustained heavy-load airflow, while the moving nozzle assembly controls response and exhaust backpressure across the operating range. Wear in the vane ring, actuator linkage, or center housing can create low boost, slow response, or engine-brake faults even when the wheels appear visually intact.

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.
