Anybody have an idea what could be causing this SKS to make a clicking sounds every time the trigger is pulled? I'm not sure what to look for once it's apart plus I don't think the trigger can be pulled anymore once it's disassembled? Thanks

 
You can still pull the trigger when removed to check it's function. You just need to hold down the arm on the disconnect to just the right level(the arm the bolt pushes down on when closed) and the hammer will fall when you pull the trigger.
 
You can test it with the stock removed. Just reassemble without the stock and can see it cycle and fire when the trigger is pulled. Easier than holding down the disconnector and pulling trigger.
 
I've been rolling this around in my brain since I read it last night. It sounds like the trigger bar still has sear engagement even with the hammer un-cocked. A few more questions:

Have you shot this rifle?

If so, have you experienced any doubling/slamfIres?

Would you make a similar video for us, but zoomed out and with the stock removed?

I'll give this a try on the weekend and post the results

I have not fired it and with only a primitive understanding of the inner workings of them I was hoping to have it fixed before firing it. I'll see if I can make a video with the stock removed and post it this weekend.
 
Sounds like the hammer has fallen but is being held up by the forward bolt position rod. If you pull back on the bolt all the way and let it close again do you still get the same click?

If I pull the bolt back, open the magazine to allow it to close, then fire it, it still makes the sound every time the trigger is pulled
 
Ok. Just watched your video again. The hammer is being hung up for some reason. The click both ways is the sound of your sear being pushed all the way forward and then being returned. Typically when it moves forward the hammer will drop. It could be missing the hammer spring, or a rusted and ceased hammer joint.

Put the safety on and press the trigger group release, then take detailed pics of the hammer and sear engagement, also the hammer pivot point. I think we can figure this out with pics for you. You'll likely see the problem once you get it apart. Post up more pics if you need hep with it.

I am embarrassed to admit that I have never thought of that...
 
There are two parts catching each other when the trigger is pulled. In the picture they can be seen thru the hole at the center of the pic. What are they called and is there a fix?

It is as i suspected. The trigger bar is being allowed to engage the sear even with the hammer forward.
The two parts that can be seen through the hole are the back end of the sear and the tip of the trigger bar. With the hammer forward, the trigger bar should be held below the sear and unable to engage it. There is a problem with your trigger group. Best case scenario is that your trigger bar is bent upward - that's an easy fix. Worst case scenario is that the disconnector tab on the hammer is worn or ground down so that it no longer properly engages the bolt disconnector when in the un-cocked position. For that you will need a new hammer assembly. It would not be safe to use a trigger group in that condition.
I hope you have heeded the advice of others and watched some videos that explain the operation of an SKS trigger. It is definitely one of the more complicated trigger groups out there. (If you need more explanation, I can try, but it's a lot of typing)

edit* It looks like your disconnector is at a pretty steep angle so your hammer is probably fine. just pull out your trigger bar and check it first - it should be straight

Much appreciated, will see what I can do about inspecting the trigger bar to ensure it's straight. Do you have any idea if trigger parts are interchangeable between all variants of the SKS?

Early carbines had an oval shape on the left wall of the trigger housing which meant they could be missing the disconnector and safety spring. Other than that, all the trigger groups are the same and you can mix and match parts with no issue.
