Good morning, I have a craftsman belt sander 6" x 48", 9" disc and I need to remove the aluminum disc because I accidentally bent it. I'm trying to pull it off using M6 screws but it won't come off, it moved about 1/8" outward but that's about it. Is there something I should be doing differently? Is there a set screw holding it? I can't seem to figure out how to get the plastic guard off to see if there is a set screw or not. Thank you, XXXXX XXXXX
I tried the suggested solution but I still cannot remove the aluminum disc from my bench sander so I replied back to the expert letting him know that this doesn't seem to be working. I'm not a mechanic but I am an electrical engineer and I do almost all of my own work so I feel pretty qualified in some ways. But still I'm starting to think that this may not work for me.
I think the screw that I need to loosen is item #2 on the "motor and disc" drawing. But I can't get at it because it is beneath the plastic housing. I can't remove the housing without first removing the aluminum disc (the disc is what I wanted to remove in the first place). There is a square hole in the top of the plastic housing that is probably there to access the screw but I can't see in there. So I don't know what to use (Phillips, Allen, or even what size to use) and I can't see how to align with the screw.
Regarding the previous work that I did: I lubricated the shaft and gently tapped it back into its original position. I saw the set screw that you mentioned that is 4 1/2" inward and loosened it but I don't really see what that does as far as removing the aluminum disc.
I do think if I can loosen that item #2 I should be able to remove the aluminum disc but I don't understand how to do that.

Just checking did you remove the set screw on the back of the aluminum disc?

I finally got the plate off. I laid it on my steel table saw top and I can see that it is definitely bent. Thank you very much for the help. As it turns out, there is actually two set screws that were holding the aluminum disc. The Craftsman 'Motor and Disc' drawing only shows one. But I was able to use the magnifier/light application that I have on my i-phone and was able to look into the hole and see the Allen set screws. I appreciate the good service that you provided.
