Help identifying part - 686-6

[Dahak]

My 686-6 stopped rotating the cylinder. So armed with a good set of screwdrivers and YouTube, I opened it up with the intent to take a look and see if I could find the issue. After tapping the side plate open, the piece attached in the picture below fell out. I put everything together again so that I didn't lose anything else and started trying to identify what came out. I couldn't find an answer.

On the plus side, the cylinder now rotates properly, so I do think that I found the issue, but without knowing what the missing piece is, I'm hesitant to start using the revolver again.

What is this mysterious part?

Looks like the plunger and spring that inhabit the yoke screw. Probably popped out when you removed the screw. (front screw in the sideplate) The misbehaving plunger came unstaked and was what was causing your cylinder rotation issues.

Check that yoke screw and see if there is a cavity inside. You'll need to purchase a new screw.

That was it! I bet I knocked the spring loose taking that screw out for cleaning sometime earlier and then it just hung out in the internals until it landed in a spot to cause the problem. Now I have one more thing on my always double-check list. Thanks for the help!
