Follow Ken's instructions and look UP! There is a wealth of Hydro info in the FAQ section. Includes pictures and how to adjust info. KW was steering you in the right direction.
Only thing I would add is: Is the roll pin in hydro side of the coupler. If it is out, it might turn it enough to move slightly.
