Replacement 8″ Split Friction Disc

This 8″ friction disc replaces the fiber discs for Twin Disc, Rockford, NACD and WPT Power 8″ PTO clutches that have the same common dimensions.  While these are usually referred to as “8”, when put together, the disc actually measures closer to 8.75″ from tip-of-tooth to the opposite tip- of-tooth/ 8″ from tooth groove to opposite tooth groove and has an interior diameter of 5.4″ and a thickness of just under 0.5″.

Split discs like this can be used to replace a solid friction disc with the benefit being that you don’t have to remove the clutch pack from the PTO shaft and take it apart just to replace the disc, however there is a trick:  The orientation of the disc segments matters so before trying to install the new split disc, make sure you can align the three disc segments inside the drive ring on your flywheel so they fit together properly and then install them into your clutch pack with the same orientation.  This will help to avoid making the process more frustrating than it needs to be.

Also replaces Twin Disc part number: 8X-290, Rockford pn: 2-03569, NACD pn: 203569AM, and WPT Power pn: WTD-08-005
