Hello and welcome to Justt Answer,
If you have alreadyy removed the bolt and tried using a puller and it is bending the lips of the pulley then you have 2 choices. You can either lift the engine to get the belt on or you can cut the old pulley off of the shaft and then buy a new pulley and put on it. I have had to cut several of them off. I always use antiseize when I put them back on.
