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.

If the belts are misaligned the v
Belts can be straight edged aligned pretty easily. I cut down a 3' metal ruler i got from harbor freight to the various sizes of straight edges i needed for my machine. However if it is the Serpentine belt that needs to be aligned it can .be straight edged buuuuuuttt, i highly highly highly recommend that if thats the case you invest in a laser alignment tool. Serpentine belts have a tolerance of only ½ngroove for every 6" between the closest pulley and the pulley your trying to align v belts on the other hand are alot more forgiving. Lif your interested in a laser alignment tool for v belts. I found and bought one off a hog farm supply for about 30 bucks but it only works on A belts not B belts. If you want it message me and ill get you the information.
