175A alternator belts

ngtnewington Newington

The saga goes on. The belts for my 24v Leece Neville 175a alternator do not last and produce dust.
So I have been scratching my head....and coming to some conclusions....

But before I go on can someone with the 175a 24v twin belt pulley set up let me know what pulley diameters you are using and what width belt and if you use cogged belt with the idlers or not?
