Remanufactured 3781360 Cummins ISX / ISX15 Holset HE451VE Turbocharger

The 3781360 Turbocharger is a purpose-matched Holset HE451VE assembly for Cummins ISX, Cummins ISX15 heavy-duty highway and vocational applications. It is built around the exact compressor, turbine, housing, and control specification associated with part number 3781360, so fitment should be confirmed from the engine serial number and original turbo tag rather than by engine family alone.

The 3781360 HE451VE is a heavy-duty Cummins ISX/ISX15 variable-geometry turbo designed for high airflow and precise exhaust-energy control. By changing vane position, the turbo can build boost quickly, regulate drive pressure at high load, and produce strong engine-brake backpressure when commanded. Correct installation includes checking the exhaust manifold, charge-air system, oil drain, crankcase pressure, and actuator calibration rather than replacing the turbo alone.

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.
