Default Model 36 cylinder issue?

I found a 1970 Model 36 in beautiful shape today, and took a chance on it. When you open the cylinder, it stops about half way down, as if it's falling into a detent, and then requires a little tug to get it completely open. The same thing happens when you close the cylinder. It stops about half way up, and then needs a little nudge to get it past that resistance so it can then be closed shut. I own lots of Smith revolvers, and this is the first time I've encountered something like this. Is this something to be concerned about? As I've played with it a little, it seems to be loosening up a bit.

Thanks in advance for your responses!

Sounds like a Yoke issue, could be the wrong screw, or something could be bent or out of round. It probably will loosen up with use, but that may not be a good thing if there is a issue. I sent my 36 back to S&W, took a while cost about $100, they straightened it out.

Might be just a bit of rust or debris in there.

Remove the yoke screw and see if it moves freely.

Also look at the frame lug and make sure cylinder is not binding on it as you open and close cylinder. But, I am betting Photoman is correct and the "button" on the end of the yoke pivot and the yoke screw are dragging against each other. Look at the groove in yoke pivot shaft for hard rub marks, a couple strokes with a real fine file or one of your wife's fine emery boards will smooth it up or just open and close it alot. Some time when I do real smooth a just place a wrap of 400, 600 or 1200 grit sand paper over the fine file. Then, all the teeth on the file does is hold the sand paper flat and guide it.

Oh, yea make sure to look if the yoke dragging against the frame or barrel a tiny bit at the top as it closes too.

Default Remove Cylinder

Removing the cylinder and crane does not require gunsmithing skills and it could just be a matter of cleaning and lubrication.
However, as with everything, there's a little trick involved: After removing the set screw, open the cylinder and lay the gun on its right side. Holding the cylinder in place, pull off the crane from both the cylinder and frame. Re-assemble by holding the cylinder in place, then inserting the crane through the cylinder and frame simultaneously.

More than likely the Yoke screw is not fitted correctly. If you back the screw out and all works properly, then fit the screw and you are done. A few drops of oil should be used when reinstalling since it a rotating part.

Sometimes when people take the sideplate off, they put the screws into the wrong holes. The yoke screw is a fitted screw, but looks identical to the screw right behind the trigger guard (both are crowned head). Simply switch the screws and see if that solves your problem. Also, just tighten the screws tight, not "bubba" tight as you can force the yoke screw past the area that has been fitted.
