It will go in.
If the roll joint has shifted at all, that can cause a hang up. But other than that, it will go right back in.

Now, there should be a small witness mark on both the pin and the frame so that the pin goes back in the right spot in order for the screw slot to point the right way when all back together.
The mark is on the threaded end of the pin at the top side.
