5-axis CNC milled compressor wheel
5-axis CNC milling supports precise blade geometry, consistent surface finish, and repeatable compressor wheel dimensions for stable airflow characteristics.
Cast iron compressor housing
Cast iron compressor housings provide a robust structure for compressor-side durability and dimensional stability in replacement turbocharger assemblies.
SiMo cast iron
SiMo cast iron is used for high-temperature turbocharger components where heat fatigue resistance and oxidation resistance are important for long service conditions.
INCO 713C nickel-based superalloy
INCO 713C nickel-based superalloy is selected for turbine-side heat resistance, helping components withstand high exhaust temperature and mechanical stress.

This HX83 turbocharger is listed for Cummins QSK38 and QSKTAA19-CE 700HP construction equipment engines. It is also associated with Cummins QSK38-G2 and Hitachi excavator applications. Buyers should verify the specific engine code, production year, and OEM reference numbers such as 2837540 or 4040239 against their equipment records. This is an aftermarket replacement application; confirm fitment with your technical team before ordering to ensure the unit matches your specific configuration.
Technical Notes
The HX83 turbocharger assembly features cast metal compressor and turbine housings joined by a central bearing housing. Visible oil supply and drain ports on the bearing housing support lubrication system integration. A metallic clamping band secures the housings, with alignment dots indicating proper assembly orientation. The turbine housing includes a flanged exhaust inlet port and an integrated water-cooling jacket. The compressor outlet port features a mounting flange with bolt holes for exhaust manifold connection. Buyers should verify these visible structural features against their specific engine bay layout and mounting requirements. Confirm that the oil port locations and cooling jacket configuration match the existing Cummins QSK38 engine installation before finalizing the order.
