The Muncie A20-A1011-HX3BBPX or A20A1011HX3BBPX is a 10-bolt clutch shift power takeoff built for Allison 3000 and 4000 series transmissions. The shift cover rotates a full 360 degrees, and the pump flange is independently rotatable, giving installers flexibility in tight engine bays. Increased clearance simplifies installation, and extended-length PTO mounting fasteners ease alignment. Tapered roller bearings extend service life, while a proven clutch pack design delivers consistent engagement. The enlarged output shaft diameter adds durability, and a maximized gear profile keeps operating noise low. Three housing arrangements are available, and the unit is compatible with an EX Drive shaft extension. Intermittent and continuous torque ratings are unified in a single rating.
