S&W 64-5 ejector rod issue.
Hello again,
I am once again in need of help with my 64-5. Recently my ejector rod has been sticking. The weird thing is, it only sticks when the cylinder is turned to a certain position, and I press the ejector rod. At every other position the ejector rod operates perfectly. I don't have any issues while firing, the cylinder turns perfectly fine etc.
I have taken a couple of pics so you guys can see what I mean.
In these pics the ejector rod is staying pressed in. And there is noticeable drag when this is happening, to the point where I can slowly let my finger off the ejector rod, and it stays in the depressed position. I.e. the pics.
Any ideas?
Thanks!

I'd guess bent ejector rod, center pin or extractor shaft. But that's all speculation without being able to handle it. Do I see plier marks on the knurl ? That may be a clue.

Concur. Do you know if the ejector rod was recently damaged in any way?
Good luck,
Dave

Not that I am aware of. Up until recently it only came out to the range once a month, then sat in the safe. So I am not sure if it's always done that on the one position, and I never found it until now, or what.

Would this be a gunsmith only job? Or can a regular joe with decent working knowledge do it? Not sure if those would all need hand fitted or not.

Did you try putting a single drop of gun oil in the groove? Sometimes helps.

It may simply be screwed together a little too tightly. Have cured this syndrome before just by getting the assembly less than gorilla tight.

The knurling on the ejector rod looks crushed in the last photo. I'd say that it has already been apart. I agree on the bent center pin. My experience is that replacement is better than trying to bend the center pin back to straight.

Update: took it apart and after cleaning it up and actually tightening it, the problem is gone. It was a little loose it would appear! Easy enough atleast. Now just gotta watch and see If it loosens up again.
Thanks for the help everybody, much appreciated!

Open the cylinder and spin it. Watch the end of the ejector rod and see if it wobbles. That will tell you that it is bent. I am guessing that is the problem. The fix is to give the rod a wack opposite the bend with a soft hammer or babbit. It should be done using a jig that supports the cylinder. I've seen attempts at fixing it while it is still in the yoke but you run the risk of bending the yoke and causing a worse problem. It's an easy armorers fix especially if they have the proper jig.

...Or it could be dirty. I would still check the run out because the lubrication might mask the problem and it will just reoccur.
