Technical Notes

The 7W3842 turbine wheel is a critical rotating component for the S4DS006 turbocharger assembly. Inspect the wheel blades for cracks, erosion, or heat damage before installation. Verify that the shaft diameter and spline count match your original unit to ensure proper engagement with the CHRA. Check for excessive play or bearing wear in the turbo core, as a damaged wheel often indicates broader internal failure. Confirm the wheel orientation and balance marks align with the compressor housing specifications.
