The Muncie A20-A1011-HX3PBPW or A20A1011HX3PBPW is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees, the pump flange is rotatable, and the housing is available in three arrangements, giving installers meaningful flexibility on a crowded chassis. Extended-length PTO mounting fasteners and increased component clearances simplify installation. Tapered roller bearings and an increased-diameter output shaft address long-term durability, while a maximized gear design keeps operating noise down. The unit carries a single intermittent/continuous torque rating and is compatible with the Muncie EX Drive shaft extension. Available from Pro Gear and Transmission.
