Hi and welcome Bill,
You just have to knock the dowel pin out (from back), and the arm will come out.

The assembly actually uses two 6mm push rods, seen on bottom right of photo.
Thanks for the phone calls, every one told me to purchase a new one so I called Al and ordered a new one. Thanks again.
