The Muncie A20-A1007-HX3BSPX-XX or A20A1007HX3BSPXXX is a medium-duty, 10-bolt clutch shift power take-off designed specifically for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack with tapered roller bearings to extend PTO service life, and the shift cover allows full 360-degree rotation for flexible installation. The rotatable pump flange and increased component clearance simplify mounting, while extended-length PTO mounting fasteners and reduced leak paths cut maintenance headaches. The increased output shaft diameter adds durability under sustained loads, and the gear set is designed for reduced operating noise. The unit is compatible with the EX Drive shaft extension and offers three housing arrangements to suit different installation requirements. Call us to confirm proper fit for your application.
