So I got my new vacuum pump and I ordered a new pulley as well because mine was bent before I had a chance to ruin it. It also had a bolt sticking in the middle which I don't think is supposed to be there but it does thread in. I read online that you can use this bolt method to press the pulleys on, so is there any harm in me using this bolt to press my new pulley to my new pump since its not the closest to me to drive and go rent the correct tool from the parts store? and once I get it pressed on, I should take this bolt out correct?
