Technical Notes

The TD05H-12B 6 turbocharger is a fixed-geometry unit, so this O ring functions as a static seal rather than part of a variable-geometry mechanism. When replacing the 49168-23200 seal, inspect the mating surface on the housing for scoring or corrosion, as these defects can compromise the seal integrity. Ensure the new O ring is lubricated with a compatible fluid before installation to prevent twisting. For Caterpillar S4KT or Alfa Romeo M631AT20C applications, confirm the specific turbo serial number against your service records to verify the correct seal size and material grade.
