The Muncie A20-A1007-HX1BBPW or A20A1007HX1BBPW is a medium-duty, 10-bolt clutch shift power take-off from Muncie's A20 Series, engineered specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, and the pump flange is independently rotatable, giving installers flexible mounting options in tight chassis configurations. Extended-length PTO mounting fasteners and increased clearance simplify the installation process. Tapered roller bearings and an increased-diameter output shaft are built in to extend service life under continuous-duty cycles. The proven clutch pack design carries a single intermittent/continuous torque rating, and the maximized gear profile reduces operating noise. Three housing arrangements are available, and the unit accepts the EX Drive shaft extension. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
