Hi, I reckon I need this part and will probably replace the belt while I'm at it. The question I have is how to remove the old pulley. I have the correct torx head for my screwdriver, but the drum turns when I try to loosen. The online videos I've seen suggest sticking another screwdriver in between the arms of the pulley, which stops the pulley from moving, but the drum stills turns and I can't seem to get enough leverage to hold the drum and turn the bolt. TIA Dom
