You can see that the cover has 2 pieces. There is a cover that snaps over the larger piece that conceals the fasteners. Pry apart, it will separate just like all the modern assemblies.

Once you have removed the cover off the larger bezel, there are a few more fasteners underneath that aluminum plate. It is slightly glued and held in place by bending the tabs. Comes out fairly easily.

This is the KEY to the whole thing. That cover is a vital mechanical component that is pressed in place. You will need to pry it off. I damaged mine slightly, with a bit of gentle heating I think you may be able to avoid damage.

Here is the disassembled unit in all its glory.

Mine had a worn bushing, on the left that caused the unit to be unbearably loud. You can see the top left of the first bushing is severely worn. I had a friend with a CNC machine make a few of these bushings. I have a few extras, contact me if you are in need of this part.
