Alternator tensioner

I have had a horrible rattling grinding noise on the engine for some time now, and I suspect it to be the alternator belt tensioner.
So went to SJB Autotech today and ordered a new one &60!! And some longer alternator belts, as the 6PK905 I have on there now is too short.
So will try a 6PK923, I need the tensioner to sit in the middle of its range, having the belt too short may add some un-due stress on the bearings which has led to it failing early.
