Servos Align ds415m stuck

Crashed..... Cyclic servo buzzing. Stuck. Took it apart and the main gear had two broken teeth (solid crash).

Gears could still be moved a bit.

Removed the gears and fired up the servo..... Buzzing.

What does this mean?. Motor shot?. Worth fixing?

Thank you.

Did you check all of the gears? It's common for it to break the second gear in the servo (the one driven off of the motor)

I did check all the gears on the great side of the servo. I removed them and it still buzzed.

I didn't get to the motor. Would I do this from the circuit board side?. Is the gear you reference available to purchase?. What's it called?. I've only seen the

I don't know what it's called. It should come as a set with the other gears. But, if the motor doesn't spin when there are no gears, then you have a bad servo. Just remember, the pot is going ot control the servo and it will buzz and the motor will move unless it's perfectly centered. which they never are.
