The Muncie A20-A1009-HX3BBPX-XX or A20A1009HX3BBPXXX is a medium-duty, 10-bolt clutch shift power takeoff from Muncie's A20 Series, engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series carries a single intermittent/continuous torque rating across available speed ratios, simplifying application selection. The shift cover rotates 360 degrees and the pump flange is fully rotatable, giving installers meaningful flexibility on tight installations. Extended-length PTO mounting fasteners and increased housing clearance further ease the installation process. Tapered roller bearings and an increased-diameter output shaft address long-term durability, while a maximized gear design keeps noise low. The unit is also compatible with the EX Drive shaft extension. Call us to confirm proper fit for your specific application.
