Here's what you begin with, hard to believe that orange piece is just sitting in there

Pull the lens out by pushing out the black tabs on the back of the assembly. You only have to pry open the part of the lens where the orange piece is under, not the whole lens. One tip is as follows,

The best way I found to under take the procedure is put the lenses in the oven for 5 mins on a piece of tin foil at 200-250 and removoe the orange put them back in the oven for another 3 mins or so that heats up the glue and press back together good as new.
