Remanufactured 4309076 Cummins ISX / ISX15 Holset HE561VE Turbocharger

The 4309076 Turbocharger is a purpose-matched Holset HE561VE assembly for Cummins ISX CM871, Cummins ISX15 applications where specified. It is built around the exact compressor, turbine, housing, and control specification associated with part number 4309076, so fitment should be confirmed from the engine serial number and original turbo tag rather than by engine family alone.

The 4309076 is an HE561VE turbo for Cummins ISX CM871 and related ISX15 applications.

Compared with the earlier HE551V generation, the HE561VE uses a revised large-frame VGT package to manage high airflow, transient boost, EGR flow, and engine-brake pressure on 2008-2010 emissions platforms. Exact calibration and actuator matching are critical because nearby 4309077 and 4309078 assemblies can represent different horsepower or flow specifications.

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.
