When you have to remove the bolt/set screw to get to the motor on your big machine so you can replace bearings or do other internal work, use an automotive oil filter wrench instead of a pair of multi-grip pliers (what everybody calls by one of the brand names, Channellocks). When you use the multi-grip pliers and squeeze them tight, the teeth really bite into the pulley and can damage it.
