There are two roll pins, one to secure the driving sleeve onto the belt pulley and one to secure the driving sleeve to the engine shaft. From your description it seems that the engine side roll pin has sheared. Drive it out and replace both sides.

The gear on the end of the cam shaft that drives the pto shaft needs looking at, there should be an inspection plate on the bottom of the engine to gain axcess to this.
