- 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. The bearings spun inside the housing causing the wear marks. We recommend plating and grinding the 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 tool pressure is low. The disc springs look worn. We will replace the disc springs and gripper balls.
- The unit will be assembled and tested.
