[AT] McCormick W-4 adventures

[H. L. Staples]

Most likely there is a roll pin that has to be removed so that it will slide
on and the pin has to be installed through a hole in the pto shaft.  This
roll pin will be retained by set screws you take out to remove the pin.  

Perhaps with the above explanation you will not be anymore confused than you
are now.
