CHALLENGE

- Replaced bearings
- Replace Bellevilles
- Replace o-rings and assembly screws
RESULT
After reassembly of all components, adjusting bearing preload, and undergoing break-in and testing procedures, this spindle passed our final quality inspection before being returned to our customer with a 1-year warranty.
