Normal
My alternator bearing seized because the bush between the pulley and the bearing allowed the bearing to rotate on the shaft generating so much heat that the bearing housing alloy plate melted. (on the M6 last august) Earlier I had noticed a loss of pulling power a few miles earlier. Check that the inner pulley facing has not got a groove in it. That was why the bushing rotated as it should press this bushing hard against the bearing. It stopped the van dead as the fan could not rotate. That was a four day excursion near Preston and with thanks to people with VW's in Preston got it running again. The man who had a wedding business had a spare alternator and delivered it to me from a job he had just done. I bet there is no one out there who has had parts delivered by a Chauffeur in a white Rolls Royce!!
