• The upper bearing housing inner diameter meets design specifications and shows no appreciable wear. No modification is required.
• The lower bearing housing inner diameter meets design specifications and shows no appreciable wear. No modification is required.
• The HSK taper is scored. We recommend plating and grinding the taper.
• The upper and lower bearings show some wear on the inner and outer
  diameters. We will replace the lower bearing with an identical bearing. The
  upper bearing is ceramic. We will replace this bearing with steel roller
  bearing that will have a maximum speed of 16000rpm.
• We will polish and deburr the drive dogs.
