- Clean, inspect overall dimensions
- Replace bearings, bolts, and o-rings
- Grind, plate, grind (GPG) the ID Pilot and rear bearing journal
After reassembly of all components and adjusting bearing preload, we put the spindle through a rigorous break-in and testing procedure to make sure it passes our final quality inspection.
This spindle passed our final quality inspection and was returned to our customer with a 1-year warranty.
