Clutches are commonly connected to a drive system through roller chains and belting. This requires that a sprocket or pulley be mounted directly to the clutch. A pilot style clutch is made for this purpose; providing a projection onto which the sprocket or pulley will seat and a series of tapped holes along a bolt circle where the sprocket or pulley will be attached. Use the link below to download the Mach III Ebook which explains the factors which must be taken into consideration when selecting, machining and mounting a sprocket or pulley for a pilot style clutch.
