This bearing housing is listed for Komatsu PC300-6 excavators equipped with SA6D108 engines. It is a reference application for the TO4E08 turbocharger model. Buyers should verify the specific part number 447450-0019 BH against their equipment records. Confirm the engine code and turbo model before ordering to ensure the correct replacement application. This part is an aftermarket component, so fitment must be checked against your specific unit.

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.

Product FAQ

Inspect the mating surfaces on the compressor and turbine housings for damage or debris. Ensure the turbo shaft spins freely and check for oil leaks before installing the new bearing housing.

Excessive oil consumption, blue smoke from the exhaust, or unusual whining noises from the turbocharger often indicate bearing housing wear. Check for oil residue around the turbo body.

If the compressor or turbine wheels show significant wear, or if the shaft has excessive play, replacing the complete turbocharger assembly may be more cost-effective than individual components.

This part is a reference application for Komatsu PC300-6 with SA6D108 engines. Verify the specific engine code and turbo model TO4E08 on your machine before ordering to ensure correct fitment.
