There are 2 things that can cause this. One is a too-tight belt as you suspected; the correct size is 9.5 x 1000, I believe. If your belt is too tight, you need to move all the spacers into the center. Perhaps that's what you meant. On these cars since the belt only drives the generator, everything works well with a pretty loose belt. As long as it doesn't squeal, it's not too loose. The other way this can happen is with a bad voltage regulator which is intemittently sticking. This will cause the generator to periodically jerk back on the belt, forcing it into the V-pulley. Eventually this will split one of the pulley halves. I have pulleys if you can't find one locally. Try VW and NAPA.
