What's it do?

 

    --Have been working on my mill and following instructions from the
repair guy who's too far away to make a house call. I found this page:
http://home.comcast.net/~tom.jelly/j%20head%20rebuild%20web%20page/j%20head%20rebuild.htm
    ..and it's been a great help. Now in the second photo the guy's
holding a dumbbell-shaped part called the pivot. In my mill this part had
broken in the middle and lemmetellya getting the innermost piece out was a real
adventure. Anyway I can't figure out what the thing does and I'm wondering
what won't work if I just reassemble and leave the pivot out.
    Explanations appreciated.

Sorry, I never took a J head apart that far.
