Technical Notes

The TO4B91 turbocharger is a fixed-geometry unit, meaning it does not use variable turbine vanes. This housing is a standalone replacement part, not a complete turbocharger assembly. Before installation, inspect the old unit for foreign object damage (FOD) such as metal shavings or debris in the oil lines. If FOD is present, flush the oil system and inspect the compressor side to prevent damage to the new housing. Verify the turbine wheel shaft diameter and material against the original specifications to ensure proper bearing alignment and stable operation.
