I'm putting a 130A alternator in my 89 and I'm having problems getting the belt back on. I have underdrive pullies on it. The part of the alternator that the belt goes on is bigger than the one that was on my stock alternator and I think this is what's causing the problems. I'm trying to put the belt on with the tensioner pretty much as loose as I can get it and it's not going on very easy. I don't know if it should be this hard and I just have to work a bit more to get it on and it will be fine, or if it will be too tight like this if I can get it on. Should I take this piece off my stock one and put it on the new one? I was attempting to take it off my old one just incase but I can't get a socket in there because there's not enough room between the nut and the wheel piece. Any help would be great. Thanks.
