In my continuing quest to figure why the hell I've got belt squeal, I'm looking into pulley alignment. Basically, I have a rhythmic squelching noise going on at idle, and a squealing noise that happens when I turn on the AC. I think the too-tight belt that Throwdown sells with the underdrive pulley set blew out my AC pulley bearings in addition to destroying the autotensioner that I already have replaced. (I would never do business with Throwdown again, as they STILL sell the incorrect belt size even after I pointed it out to them in the previously linked thread)
Anyways, moving on since I think the AC squeal is going to require replacing the AC pulley bearing (will be doing this next weekend). What I did was take a straightedge piece of steel and line it up with the power steering pulley and the AC pulley. I then took a picture of the distance between my straightedge and the lightweight alternator pulley, and there's a pretty huge gap:
Could someone check their stock-Accord and tell me if there's any gap between your alternator pulley and a straightedge connecting the AC pulley and PS pulley? I'd rather have some confirmation before I spend $60 on tools to remove the alternator pulley and replace it with the stock one.
