remove top link roll pin on taishon 304

Never mind, figured it out.  The parts manual indicated that the part that the roll pin goes through is threaded.  Put a bar through the link and turned it and out it came.  Popped the pin out.  Had to try several times to get the yoke (?) threaded in far enough to put the pin back and then turn the whole assembly back in place.  Readjust the linkage inside the hydraulic box and lo and behold it seems to work.  Not sure why it came out in the first place with the exception that the previous owner had it out and never new how to put it back correctly.  Now if I can only find my COOLEY hat that my daughter says I have to wear when using the tractor????!!!?”?”
