Got my gun back from S&W

[bdjansen]

Thumbs up to Smith and Wesson for standing behind their product and fixing it quickly. I had a new 637 that I bought new and had weak primer strikes. They sent me a next day mailer. I sent it off and got it back a week and a day later.

Said they replaced the firing pin and repaired the yoke.

What is the "yoke?"

 

[takhtakaal]

The yoke is what the cylinder hangs off of. Here you see the frame (solid part of the revolver), the cylinder (the spinny thing), and the yoke, which swings out like an arm from the frame and upon which the cylinder spins.

2-3 Weeks

It only took them 2-3 weeks for them to repair my M686-6+ -- and they had to replace the entire frame (a broken stud). I've had nothing but good service with Smith.

So if they said that they adjusted the yoke, what do you think that means? I'm not sure how you would adjust that part.

 

[takhtakaal]

The rod is what the cylinder actually spins on. Sometimes the yoke (think it's also called a crane) is out of spec and need to be straightened so that the cylinder goes around as it should on the balance of the ejector rod. It can also have issues at the frame where it is retained by a detent screw. If you go to Numrich's website, they have fairly detailed schemtic blow-ups for a lot of firearms.

So if they said that they adjusted the yoke, what do you think that means?

I would interpret that to mean they adjusted the endshake of the cylinder. It is done either by peening the barrel (of the yoke, not the shootin' barrel) and trimming, or shimming. I would presume the factory uses the former method, but I have never had to send a gun back to them.

Adjusting the yoke usually means taking a big hammer and whacking it hard to move it in the desired direction. I'm not making this up.
