Pulleys Squealing?

[Bryce C]

Does this sound like a pulley about to go bad?

I bought a mechanics stethoscope for identifying these things a while ago. Never used it. I suppose now would be a good time to try...

Squealing belts are almost eighter loose belts, badly worn belts . But more often than not its caused by misaligned belts. Especially if there is little or no vibration. Check idler pulleys but my moneys on alignment or loose belts

One other thought is contaminated belts. If you have been doing alat of work around them perhaps you got some grease or other products on them

I replace my idler pulley every time I replace my belts. I also pack it with hi temperature grease.
