Read some of the posts about belt shredding and belt alignment,Dayco has a alignment kit,part number 93874,has gauges and
laser levels,retails for about $100.One is on ebay for $59.
Here's a video of how they work. http://www.youtube.com/watch?v=lOBSKjKdwek
I just use a straight edge for alignment, or a string.
Glad to see the Dayco video, very interesting but I never use Dayco Belts, always change over to the Gates Brand, much better long term luck.
Same here and also just put on a gates belt tensioner,much better then dayco.
