Fixing infinity focus on Canon 20-35mm f2.8L

Hi Folks, I picked up a nice condition 20-35mm f2.8L on Ebay.

The lens zooms fine, and the focus motor works fine, but the lens does not focus to infinity even if I manual focus to infinity. It seems to get to about 10 meters and thats it.

Now I've taken the front off the lens, and I'll take some photos to show the insides. Does anyone know how to adjust an EF lens for infinity focus?

To clarify the lens shows infinity on the window on the top of the lens but it isn't focused to infinity.
