Technical Notes

The TO4E08 turbocharger is a fixed-geometry unit, meaning it does not utilize variable turbine geometry or adjustable vanes. The bearing housing serves as the central structural component, supporting the turbo shaft and maintaining the critical oil and coolant seals between the compressor and turbine sections. During inspection, verify that the housing bore is free from scoring or excessive wear, as this directly impacts shaft alignment and operational stability. Ensure the mating surfaces are clean and undamaged before assembly to prevent post-installation leaks. Buyers should confirm the specific part number 447450-0019 BH against their equipment records to ensure the correct replacement application for their SA6D108 engine.
