Inspection Results:

  • The lower spindle journal diameter is worn and undersized. The lower
    journal also has runout where the bearings sit. We recommend plating and
    grinding this area.
  • 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 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 unit will be assembled and tested.
