The Muncie A20-A1007-HX5PBBX or A20A1007HX5PBBX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. It uses a proven clutch pack design with tapered roller bearings to extend service life, and the shift cover rotates a full 360 degrees for flexible installation positioning. A rotatable pump flange and increased clearance around the unit simplify mounting, while extended-length PTO mounting fasteners and an enlarged output shaft diameter add durability under load. Reduced leak paths and a maximized gear design keep noise low during operation. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. A genuine Muncie part from Pro Gear and Transmission. Call us to confirm the correct configuration for your application.
