This is the Holset 3798382HX, an HE351VE variable geometry turbocharger for the Cummins ISB 6.7L in medium-duty service, remanufactured by Holset (Cummins Turbo Technologies). It comes without the electronic actuator, so you move over the actuator from your old turbo or fit a new one. It crosses to Cummins 3798331 and exchange number 3798331RX, and the new version of the same turbo is Holset 3798382H. A refundable core applies.

These turbos are replaced for a nozzle ring stuck with soot, low boost, a weak exhaust brake, turbo speed or actuator fault codes, oil in the intake and shaft play. If the actuator is the only thing that has failed, the turbo may not need replacing. If the turbo has failed, check the actuator before you reuse it. Some catalogs call this same number an HE300VG, so order by the part number on your old turbo and not by the model name.

Specifications

Fits / Applications

• Cummins ISB 6.7L in medium-duty (midrange) service, with the Holset HE351VE turbocharger
• Replaces Cummins 3798331 and 3798331RX
• Supplied without the electronic actuator
• Not catalogued for Ram pickups. Check the engine serial number.

The turbo comes without the actuator. If you reuse the old one, check that it moves freely and has no fault codes first. A new or swapped actuator has to be calibrated to the turbo with the Cummins or Holset service tool after fitting. Fit new gaskets, check the oil feed and drain for restriction, and clear the cause of the old failure (soot, oil supply, a foreign object) before you start the engine.
