Introduction

The motor powers the rotating head of the toothbrush. If it is damaged or wears out due to use, it will need to be replaced. Some steps in this procedure require desoldering connections. For a review of soldering techniques, check out this How to Solder Guide.

Push on the rotating head in order to pop the assembly out of the black plastic casing. You can also use a spudger to leverage the assembly out, but this may break the copper wire connected to the induction coil, so be careful.

Remove the motor housing from the plastic casing. This can be accomplished by using the nylon spudger to pry the motor housing out of the supporting structures. The physical parts holding onto the motor are plastic knobs built into the plastic casing. Any manipulation done to the casing to remove the motor should be done within reason so that the casing is able to be reused.
