I have what is most likely a dumb question, but I haven't been able to get an answer anywhere else. I'd appreciate it if someone could help me out. Here it goes: the alternator went in my 1991 Buick Skylark with the 4 cyl
2.5. So I ordered what I was told was a suitable used replacement, but I got it, and it doesn't line up properly for it to fit. The back of it (non pulley side) is 120 degrees off. I'm suspecting that it is possible to rotate it, so I took of the three screws on the sides of it, but I can't rotate it the full 120 degrees because the two parts of the outer casing hit. Is there a trick to this? Do I just have to take the nut off the pulley so I can pull the case apart and rotate? That's what I'm going to try when I get back from the hardware store with the socket I need, but I just wanted to make sure. Thanks in advance. Chris- posted
