HS-485 Servo Screw Stuck

Hello,

I am trying to remove the horn from the hub of the servo, but am unable to remove the screw. I tried removing it a number of different ways, but it would not budge and the screw is now stripped. Is there any way of salvaging the motor or do I need to get a replacement.

Thank you,
Matt

Hello @matthewlouismueller

Can you share some photos of the stuck screw?

There are some techniques that can be applied so you can remove stripped screw (like cutting it’s head and then trying with bigger flat screwdriver).

Happens to me more than I like.

My recovery plan is:
1: Accept the fact the horn and the screw are scrap.
2: Use my Dremel-like-device (DLD) to cut a deep slot in the head of the screw and try a flat blade screwdriver to remove the screw.
3: If that doesn’t work, use my DLD to cut the head off the screw, as high as possible. By “high” I mean, far away from the body of the servo. That should allow me to remove the remains of the horn and get to the shaft. I’d clamp my Mole-grip-like-device (MGLD) on the shaft and twist the screw out.
4: In the process I’d strip all the gears in the servo & render it useless.
5: I’d remind myself not to tighten them up so much next time and bin the servo. Cursing as I went.
6: I’d visit eBay, Amazon or my other favorite servo source and tell them what I’d done, in an effort to lighten their day.
