[QUOTE="Peter Good, post: 592641, member: 13547"] Sorry to question your diagnosis, but I disagree with the cause of the failure. What is happening is that the pulley nut has effectively bottomed on the shoulder just below the threads on the alternator shaft. As a consequence what feels like a fully tightened pulley nut is in effect applying a much reduced pressure on the pulley itself. The photos clearly shows the cause is a loose pulley even though the pulley nut was tight but ineffective. The argument about fitting a 'quality' pulley, better made, higher grade of steel / material, is by and large masking the problem for longer before it surfaces again. Unless you address the real cause it will eventually re-occur. Peter Good [/QUOTE]
