The Muncie A20-A1011-HX3TAPX or A20A1011HX3TAPX is a medium-duty, 10-bolt clutch shift power take-off designed specifically for Allison 3000 and 4000 series transmissions. The A20 series uses a proven clutch pack design with tapered roller bearings to extend service life, and an increased-diameter output shaft for greater durability under load. A rotatable pump flange and a shift cover with 360-degree rotation simplify installation and plumbing. Reduced leak paths and a maximized gear design keep noise down. Three housing arrangements are available, and the unit accepts the Muncie EX Drive shaft extension. Extended-length PTO mounting fasteners are included.
