  • Due to corrosion and fatigue cracks, it is recommended to undertake crack detection check preferably by magnetic particle test (MPI) or by dye penetrant test. This should be essentially undertaken by qualified technician.
  • Hardness Test – The hardness on the bearing seating area should be checked.
  • It is important that the turbine shaft bearing seating diameter is free of any bearing line marks, pitting, corrosion, etc and has the surface finish as per the international norms. This can be checked and surface finish can be improved by polishing the bearing seating area.
