I recently purchased an M7 16% reduction Supercharger pulley and finally got to installing it. Long story short, after hours of tear down and special words I saw an Alta 15% reduction under the tensioner ...... I purchased the pulley puller in order to remove what I thought was the OEM pulley and now I don't quite know how to remove it. Is it as simple as just removing the key bolts in the center and pulling the outer collar off and then the center collar? I'll have to remember this for whenever I get to pulling the front off again.

 

Three bolts on the end come off and then the pulley will come off. Then there are two bolts that hold the collar on. Just loosen them until the collar slides off. Pretty easy actually.

So to answer your question, yep, it is that easy.
