The Muncie A20-A1006-HX5BBPX or A20A1006HX5BBPX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design and tapered roller bearings to extend service life, while an increased output shaft diameter adds durability under sustained load. A rotatable pump flange and shift cover with 360-degree rotation simplify plumbing and mounting in tight installations. Three housing arrangements give installers layout flexibility, and extended-length PTO mounting fasteners ease fitment. The unit is also compatible with the Muncie EX Drive shaft extension.
