Remanufactured 4352561 Cummins ISC 8.3L / ISL 8.9L Holset HE400VG / HE431VE Turbocharger

The 4352561 Turbocharger is a purpose-matched Holset HE400VG / HE431VE assembly for Cummins ISC 8.3L, Cummins ISL 8.9L. It is built around the exact compressor, turbine, housing, and control specification associated with part number 4352561, so fitment should be confirmed from the engine serial number and original turbo tag rather than by engine family alone.

The 4352561 is an EPA10-era HE431VE/HE400VG calibration for Cummins ISC 8.3L and ISL 8.9L engines. It provides variable turbine control for boost response, exhaust braking, EGR flow, and aftertreatment support while handling the sustained airflow of medium- and heavy-duty operation. Exact ESN verification matters because adjacent Holset assemblies can differ internally even when the housings and actuator mounting appear similar.

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.
