The Muncie A20-A1005-SX3CBPW or A20A1005SX3CBPW is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series design centers on a proven clutch pack with tapered roller bearings that extend service life, an increased-diameter output shaft for added durability, and a rotatable pump flange for flexible mounting. The shift cover rotates 360 degrees, making it adaptable to tight installation environments, while extended-length PTO mounting fasteners and increased clearance simplify the install. Reduced leak paths and a gear profile optimized for noise reduction are built into the housing. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension.
