The Muncie A20-A1005-HX1BB or A20A1005HX1BB is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series design includes a shift cover with 360-degree rotation and a rotatable pump flange, giving installers more flexibility in tight mounting situations. Tapered roller bearings extend service life, while an increased output shaft diameter adds durability under load. The unit uses a proven clutch pack and a maximized gear profile to reduce operating noise. Three housing arrangements are available, and the mounting fasteners are extended length for easier fastening. The A20-A1005-HX1BB is also compatible with the EX Drive shaft extension.
