  • Sometimes with all the wear and tear of use (especially if you have 19 of them working in a robot...), servo gears need to be replaced. It's a much cheaper alternative to buying a new servo. Here's how to do it!
  • You'll need:
  • A fine Phillips-head screwdriver
  • Replacement gears
  • Broken servo

  • We're specifically going to look at changing the highlighted gear. It's the one that breaks 95% of the time. The other gears are replaced in a similar manner.
  • Wiggle out the two gears that are on the same metal rod, and remove them.
  • Place one of the replacement gears in their place.
  • Put the servo back together in the reverse order that you took it apart.
  • Servo fixed!
