The rotor re-machining has been successfully performed in the factory Birr. A final runout measurement after re-machining has been carried out according specific I&T Plan. All the values of the re-machined areas are in line with our technical specifications.
All the required tests have been passed according I&T Plan. The rotor has been successfully remachined and is ready to re-balance. With the re-balancing we want to ensure that the balancing quality,as achieved during final acceptance test, has not been compromised by re-machining of the DE-Bearing area. As of the new rotor dimensions, the DE bearing shell, shaft seal ring and oil wipers of the shaft seal
labyrinth needs to be replaced or reworked.
