The Muncie A20-A1010-HX3ZBPW or A20A1010HX3ZBPW is a medium-duty, 10-bolt clutch shift power take-off from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, and the rotatable pump flange simplifies pump positioning during installation. Increased clearance around the unit eases the install process, while extended-length PTO mounting fasteners give technicians more working room. Tapered roller bearings extend service life, and the increased output shaft diameter adds durability under load. Gear geometry is optimized to reduce operating noise, and reduced leak paths cut down on maintenance. The unit carries a single intermittent/continuous torque rating, is available in three housing arrangements, and is compatible with the EX Drive shaft extension.
