Heard a noise that sounded off while driving the cruiser home from work today. I opened the hood to find the power steering pump belt rubbing against the smog pump pulley, as pictured. There was also a faint clattering noise that I guessed was coming from the smog pump. I took off the belts and tried turning both pulleys by hand. the power steering pump feels normal, the smog pump I can feel compression and release but sometimes it catches, confirming the clattering noise that I had heard before. Furthermore, the pulley seems to be off of true, so that as I turn it by it has a wobbly motion. What I don't understand is what is out of clearance that's causing the power steering pump belt to rub against the smog pump pulley?
I was expecting to find axial play in one or both of the pulleys, but that isn't the case. There is no play. Anybody seen anything like this before?
