Technical Notes

The HX83 turbine wheel features a radial design with curved blades and a long central shaft, visible in the supplied studio images. The shaft includes a threaded section at the far end and a polished finish, while the wheel blades show a dark, matte surface. These visual cues help buyers confirm the physical form factor against their existing component. Since material composition and exact dimensions are not visible in the images, verify the specific material grade and dimensional tolerances against your Cummins QSK23 engine requirements. Cross-check the part number 3535721-CAST-1 and relevant OEM references, such as 4034072 TW or 4040782, to ensure the correct replacement application for your Hitachi EX1200 unit.
