Hi Kristin
Go down and RENT a gear puller, I have many of them and they are not cheap to buy.
The one you want to rent is a split type, that's to say it comes in 3 parts,or 2 parts, the back plates will slip behind the wheel, then you have a front plate with holes for the bolts..if you want to see a quick snapshot just ask.
Once you have it in place put just a bit of heat to it with a propane torch...but not on the center of the shaft..
DON't use the 3 jaw type you don't want to damage the pulley..plus they will not fit behind the wheel...cheaper than replacing the wheel...
The last time I rented one it was 7.50...per. day....
