I bought a new OAD for my alternator because the old one was squealing. I didn’t realize when I bought it that I would need a factory tool to remove it. After staring at the problem for a while, I was struck with the idea that I could rig something that would work. Here’s my solution. I bought a “close quarters” ¼” drive 10mm socket on the internet for $5 (including shipping) and then bought a ½” threaded rod connector (which just happens to have an external hex of 17mm). The connector is large enough for a ¼” extension to fit through and then snap the socket on the end and voila! The connector fits perfectly in the pulley hex so you can hold it from turning and the socket has plenty of room to turn to remove the bolt holding it to the shaft. I don’t have pictures of it in action because I am waiting for a new tensioner and belt pulleys to arrive (I’m just doing the whole thing at once). I did carefully pop the cover on the pulley that’s on the vehicle and confirmed that this set up works. Just thought I would pass it along in case anyone else needs to do this. Pics below…

Wow was I wrong! I had to remove the alternator, soak the bolt down with penetrating oil about 6 times over a 24 hour period before it would budge. Then I cracked the socket (luckily I had another that I found in an old toolbox that was collecting dust in the corner). Finally success. I have to be honest, this worked, but if I had it to do all over again I would seriously consider just buying a rebuilt alternator. Still, I saved about $70 so I'm happy.
