Remanufactured 3798318 Cummins ISB 6.7L Holset HE351VE Turbocharger

The 3798318 Turbocharger is a purpose-matched Holset HE351VE assembly for Cummins ISB 6.7L, Medium-duty Cummins ISB applications requiring the HE351VE family. It is built around the exact compressor, turbine, housing, and control specification associated with part number 3798318, so fitment should be confirmed from the engine serial number and original turbo tag rather than by engine family alone.

The 3798318 belongs to the Holset HE351VE variable-geometry family used on Cummins ISB 6.7L applications. The compact VGT architecture is designed to produce useful boost quickly during acceleration while opening at higher flow to control drive pressure. Correct vane travel, actuator indexing, and exhaust-brake response must be verified after installation so the ECM sees the expected turbo position throughout its sweep.

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.
