Oh, I hadn't thought of the possibility that he was referring to the alum pulley. If the pulley comes loose it is likely to mess up the face of the steel fan where it mates. If this face is uneven then the pulley can never run true and this will create the problem you see. I had a fan like this that Berg finally took a light cut on in their lathe. Once this surface was faced off square again everything was fine again. They did this for free, in the course of balancing everything. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- List info at http://www.vwtype3.org/list or mailto:help@vwtype3.org
