Replaced belt today, Squealing gone.

I found this document but not really sure how I would measure it effectively. I'd likely go with the belt deflection at point B, but how to determine 22 lbs, I'm not sure.

EDIT: After looking at a hardware website, I may pick up a small spring scale with a hook. Canadian Tire has a 50 lb scale for a decent price. I could run a straight edge across the pulleys joining section B, pull down on the belt with 22 pounds and measure deflection.

Yeah. You should be careful overtightening the belt because you could burn out the bearings on the pulleys if you leave it like that for a while.

To be honest. When I did it, I used my calipers and opened them to 11mm. Positioned them roughly in the middle of the belt and then tugged with my finger to measure the deflection. Not to hard and then eye balled it. Seems to have worked pretty well. I'd start a little loose and then maybe add some tension if it squeals.

Yes, however I do it, I will do it soon. I'm going to look through our shop today and see if we have any kind of scale that I can use. And, I'll follow your advice of starting looser and adding a bit of tension each time to eliminate squeal. Thanks.
