Installing a Lamonster Belt Tensioner - are there any parts underneath that need to be removed?

[ulflyer]

I'm going to replace my OEM belt tensioner with one from Lamonster. I did one once on an F3 but my current RT has lots more plastic. My question is: after I remove the 3 pieces of plastic on the left side, are there any other parts underneath that have to be removed in order to do the installation?

Unless you are a magician, you will need to remove the large front-to-back black panel as well. It looks a lot worse than it is. I usually remove the small black panel 1st as well.
