The Muncie A20-A1005-HX3BBXX or A20A1005HX3BBXX is a medium-duty, 10-bolt clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, and the pump flange is rotatable, giving installers flexibility in mounting orientation. Three housing arrangements are available within the series. A proven clutch pack design, tapered roller bearings, and an enlarged output shaft diameter work together to extend service life and improve durability. Maximized gear design keeps noise low, while reduced leak paths and extended-length PTO mounting fasteners simplify installation. The unit is also compatible with the EX Drive shaft extension.
