Squealing belts

Hello Everyone.

I think this might be a more basic question but I have been puzzling over it for a while.

I was doing some freshening up in the engine compartment, so I changed the belts(power steering and Alt.) on my BBC. The old belts were getting all cracked on the underside. I went to Napa and bought the Napa brand belts (looks like the gaterback belts) and everything seemed ok for a few days of driving. Now I get a squealing when I rev the engine (not all the time but becoming more frequent.)

1)The belts seemed to be a tad bit larger in size not length could that be a factor?

2)Could the belts be too tight?

3)Could the belts be too loose? I do not think they are too loose as there is not a lot of movement on the belt when I push on the stretch between 2 pulleys.

4)Would the belt dressing spray really fix the issue or is that just a band-aid to an issue that will return?

5)Is this a sign that the pulleys on the PS pump and the Alt are becoming worn out?

6)I have heard that you can take a scratch pad or steal wool and scuff up the pulleys valley to remove any sort of built up debris that could be causing the belt to slip. Is there any truth to this?

Any help would be great.

NAPA belts, at least in Canada, are actually made by Gates ... which is a well-respected manufacturer.

Yes, if those pulleys are showing a lot of wear, they should be replaced. It's all about contact area. V-belts should always be run-in, and then adjusted again. I would caution you not to over-tighten them, though, as that gets very hard on bearings.

As a general rule-of-thumb, you should be able to deflect a v-belt 1/64" per length of span (center-to-center of the pulleys)

The e-How website has a couple or more articles on this:
How to Measure V Belt Tension | eHow.com
How to Adjust Alternator Belt Tension Without a Gauge | eHow.com


If you really want to make sure ...Gates and Dayco both market a belt tension tool called the "Krikit"
Gates Part # 91107, Dayco # 93865

I used to work with a guy - had an old VW bug. His belt was screeching - we told him to check the tension by deflecting the belt between pulleys with his finger... he did it while the engine was running! To make matters worse, he pushed on the inside of the belt. As he applied pressure, the belt took his finger right into the pulley - clipped the last 1/2" of his finger right off! Later he said "Well nobody said I should turn it off first!".

Squealing belts

It would be in your best interest to check out some of these pulleys. They also come in sets with accessory brackets too. Billet Specialties Crankshaft Pulleys 79220 - SummitRacing.com. I remember when I had the black painted factory pulleys on my 454 motor. Everytime I would wind it out to 5000 rpm it would throw the belt. I finally got tired of looking at the March Pulley systems and wishing I had it. I bought a serpintine conversion pulley kit with crank, water pump, and alternator pulleys and the brackets for the alternator.
