This kit provides the components required to fit a Centrifugal Specialties X-10 drive with the Gen II dual hex accessory drive. This drive will permit the installation of a pair of accessories using 3/8" hex shafts and "Enderle" 3 or 4-bolt mounting flanges. This setup may also be retrofitted with V-band/Marmon Clamp adapters for use with flanged pumps/accessories. Marmon clamps and adapters are available separately. Adapters are also available for use attachment of Star Products vacuum pumps (adapter shown in photo, not included). This kit utilizes 8mm "HTD" style sprockets and operates accessories at 50% of crankshaft speed.
