    The technology that goes into making drive belts these days means that they barely stretch at all. However, a V-belt will ride lower in the pulleys as it wears, making it seem like the belt has stretched. The large adjustment available for the alternator accounts for slight variations in the actual length of new belts and leaves room to easily install a new belt. 2 inches may be plenty of adjustment if you use a belt that is on the tight side to begin with. /forums/images/icons/cool.gif

    the v belt on mine stretched a good bit.ii had a 58 inch on mine and it stretched all the way to within 1/2 inch of the end of the bracket. that is after going around the harmonic, p/s, alt, and fan. sorry i didnt get you that pic i couldnt get ahold of a camera.
