This may be a stupid question but i'd rather be safe than sorry. I've looked at all the videos and stuff to replace the coupling in my supercharger (which I will be doing within the next few days) and I saw on one place a guy said when you pull the nosecone off it breaks some sort of gasket or seal and you have to replace it but i've never heard of it anywhere else.. Is there some sort of gasket/seal type thing on the nose cone? and does anyone have any tips for replacing the coupler? Any do's/don'ts? I'm new to all this so any advice would be greatly appreciated.
