How to rebuild motor?

@singh15474 that depends on what it is that your motor does. It should always be possible to replace the bearings and sometimes even fixing the commutator if the brushes damaged it etc. All will depend on the motor and the damage. Is this your device Ridgid Wet/Dry Vacuum WD19560 and what are the issues with the motor? What have you checked?

Thanks for replying. Yes, it’s the Ridgid Wet/Dry Vacuum WD19560. Before it completely stopped, the motor was making strange noises, almost like something was broken inside. After a few more uses, it finally stopped working altogether.
