Last weekend I picked up an OO grade LC Smith with a rotary joint check, the gun was made in 1899. It has 2 small problems. First, when I break open the gun the extractor starts to rise (kind of weakly) and when the barrels reach the stop point, the extractor falls back onto the barrels. Second, when I take the barrels off, the cross pin in the rotary piece wants to fall out. Is that due to a weak spring inside the joint check? If so, how do I get the rotary piece off of the lug?

thanks,

Take the cross pin out, rotate it backwards to get the plunger into the rotary piece and it will come out the side. Mark II

Jack, not sure what you mean by the cross pin wants to fall out.
Do you mean the 1/8" pin that is in the barrel lug before the rotary bolt? On some this is invisible and you sometimes have to use a dye to find it.
To check if the spring is broken, have the barrels upside down and rotate the pin so that the extractor moves out and then push on it while holding the pin and see if you feel resistance.
To take the rotary bolt out, drive pin out in barrel lug, push slanted plunger in and then rotate pin to I believe 12 clock, and slide joint check out. (been a while since I took one out)

The cross pin I am referring to is the one that rides in the frame and rotates the joint check. I will try your suggestions.

Thanks,
