You do not need to take anything off except the vacuum pump. Get a 10mm ratchet wrench and box end wrench or a flex head ratchet wrench. You have to loosen all of the bolts equally since you can not just pull them out because the pulley is in the way. Once all the bolts are out, pull it out until you can get to the clamp that holds the hose on the back and take the hose off, keep the clamp because you will need it again. Then you need a pulley puller, not one with jaws, but one that clamps on the hub of the pulley. Pull the pulley and use the same puller, but use it to install it, you can rent one of these pullers from O'reillys, I bought it from them, it was like $30. To install it I put the pump in the fridge or freezer and then heat the pulley in the center, not directly though, I set it on a piece of steel and get it pretty warm and install it that way. Make sure you put all of the bolts in first, otherwise you will just have to pull the pulley again. The idea behind the heating and cooling is that the heat expands the pulley and the cold shrinks the shaft, that is just what I read, works for me, not saying it is true.
