Inspection Results:

  • The spindle journal diameters show no appreciable wear and are acceptable for proper bearing fits.
  • The upper bearing housing inner diameter is larger than design specifications and shows some wear. We recommend plating and grinding the upper housing.
  • The lower bearing housing inner diameter meets design specifications and shows no appreciable wear. No modification is required.
  • The taper runout is acceptable. Our proposal provides no repair to the spindle taper.
  • The upper and lower bearings show some wear on the inner and outer diameters.
  • The gripper balls on the drawbar will be replaced.
  • The stator passed the phase and insulation test.
  • The proximity switches work fine and will be set at time of assembly.
  • The unit will be assembled and tested.
