So today I took the (new to me) S&W Model 19-4 revolver to the range. It was the first time the gun had been fired in 20+ years. Prior to shooting the gun operated fine. I shot around 56 .38 special rounds and 50 .357 rounds out of it. When I got home and went to clean the gun I discovered the cylinder seems to have a rough spot. That is, if I flip the cylinder out and go to spin it, it spins freely about 330 degrees and then the last 30 degrees take a decent amount of force to push it around. You also notice the rough spot when dry firing the cylinder thru the 6 shots. I don't see any visible reason for it to be stuck. I've tried spraying some Rem Oil on the cylinder by the rod where it connects to the body of the gun and hoping it runs down the shaft to loosen things up. We'll see how it goes.

 

Anyone have any other ideas or thoughts on what to do?

Sounds like it needs a good cleaning..i get this with my smith 686 once in a while..just dirt..

Wait for Pizza Bob on this one. It could be a crane or ejector rod issue.

 

You know thw ejector rod and cylinder can be removed, right?

It looks like to get the cylinder off you have to dissemble the gun using a flathead screwdriver. That would be my next course of action but I'd like to hear other options before I have to take anything apart.

I watched the first 3 mins of this video.

At 2:45 in the youtube video shows the crane removed from the cylinder but the ejector rod still in the cylinder. Unfortunately he skips over the part I'd need.

 

 

OK, took a look at that screw. It wasn't even hand tight on... a little bit looser than that. Anyway, I took out that screw and then slid the crane forward and out of the cylinder. I put some Hoppes on the exposed cylinder on the crane that fits inside the cylinder and it definitely had some black soot on it. Cleaned it off with a rag and put it back on the cylinder but it's still rough. I took it out again and there's still soot on the crane cylinder. This is because of the fact that the spring ejector goes thru the center of the cylinder as well. Because of this I can't get anything in there to clean it with solvent. I guess I need to find out how to remove the ejector rod from the cylinder.

Since you were able to remove the cylinder from the crane, did you thoroughly clean the inside and outside of the crane "sleeve", on which the cylinder revolves? Doubtful that you have a bent extractor rod as that usually manifests in the cylinder being hard to open. If you must remove the extractor rod, insert 6 snap caps or empty cases in the cylinder to lock-up the extractor star and clamp the knurled end of the extractor rod in a padded vice. The extractor rod can now be unscrewed by grabbing the cylinder and turning clockwise - yes, I said clockwise - the extractor rod is reverse threaded. Once disassembled you can thoroughly clean and reassemble. Good luck.

 

Adios,

PS: IIRC, there is a You Tube by Midway on this disassembly. Search under "bent extractor rod"

That's the issue. I cleaned the crane sleeve on the outside, but where it slips over the extractor rod but inside the cylinder is where there is still grime. That's what I need to clean. I'm going to drop some Hoppes 9 down the extractor rod into that cylinder and let it sit for a few minutes and then try to scrub it with pipe cleaners. Hopefully that will break it up.

 

As for the extractor rod being bent... I really doubt it. It seems straight to me and there is no problem at all with popping the cylinder in and out of the gun. Just a rough spot when one of the cylinders cycles around.

I don't think you are listening to or understand what Bob said. Remove the extractor rod from the cylinder and do a through cleaning.
