Remanufactured 3772934 Detroit DD15 Holset HX55 / HE500FG Turbocharger

The 3772934 Turbocharger is a purpose-matched Holset HX55 / HE500FG assembly for Detroit DD15, Heavy-duty highway and vocational DD15 applications matching OE fitment. It is built around the exact compressor, turbine, housing, and control specification associated with part number 3772934, so fitment should be confirmed from the engine serial number and original turbo tag rather than by engine family alone.

The 3772934 is an HX55/HE500FG-family turbocharger used on specific Detroit DD15 applications. Its robust fixed-geometry layout is built for high mass airflow and continuous heavy-duty operation. The turbo should be matched by Detroit OE number and engine configuration because housing orientation, outlet geometry, and internal wheel specifications can vary across visually similar HX55-family assemblies.

This listing is supplied as the turbocharger configuration shown. Correct installation requires clean oil feed and drain paths, a sealed charge-air and exhaust system, proper air filtration, and confirmation that the original failure did not leave debris or contamination in the engine system.

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.
