BB Collars: See our CATALOG to find the correct part to upgrade your PTO clutch…
Ball Bearing Collars are now available for 6″ PTO’s through 3 plate 14″ PTO’s. All parts are completely interchangeable with Twin Disc. The 2 plate and 3 plate 14″ PTO BB Collar Assembly is interchangeable, but the components used in the Assembly are NOT due to the proprietary bearing Twin Disc uses in their assembly.
