Belt length for a 68mm pulley??

[G40Valverpaul]

As the title please, what length belt do I need for a 68mm pulley??

[PeteG40]

fine with the same belts - as the charger pivots to tighten them up

[G40Valverpaul]

So its the same belt for a 68mm as for the standard 75/78mm(??) pulley?? Is it worth getting the tensioners changed at the same time then do you reckon??

[hayesey]

there are no tensioners for the charger belt, the charger itself is the only tensioner

Told you I did'nt know much about mechanics!!
