Different question. Anyone know what the part number on there driven clutch is. I can find salsbury 780 driven clutches online but with a couple different part numbers stamped on them. The manual says 125-38 (152004). These aren't the numbers I'm seeing. Or is a 780 a 780. I'm seeing the 780 with a 1 in bore & a 1/4 keyway and a 8.5 inch outside diameter. Rather match the clutch than guess at belts. Thanks for the help.
