The Muncie A20-A1010-HR3X4 or A20A1010HR3X4 is a medium-duty clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design with tapered roller bearings to extend PTO service life, and an increased-diameter output shaft for added durability. A shift cover with 360-degree rotation and a rotatable pump flange simplify installation and plumbing layout. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Extended-length PTO mounting fasteners and increased clearance reduce installation time.
