The upper pulley is a two piece setup. There are shims that you use to widen up or narrow down the gap between the two halves of the upper pulley on the Alt/Gen. Too tighten, you take the nut off the outer pulley and there should be a few shims between the nut and the pulley. Put them down for now and take the outer pulley off and there should be a few shims in between the halves. Depending on how loose the belt is you start taking the shims out one by one until the belt is tight. Then you put the extra shims and add them to the others that were already on the outside and retighten the nut. It may take a few tries to get it right. If you can't get the belt tight then either the belt is worn out or the wrong on is on it.
