The Muncie A20 Series 10-bolt clutch shift power take-off, part number A20-A1009-HH3BBPX or A20A1009HH3BBPX, is a medium-duty PTO designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, and the pump flange is also rotatable, giving installers flexibility in tight engine compartments. Extended-length PTO mounting fasteners and increased housing clearance simplify installation. Tapered roller bearings and an increased output shaft diameter address long-term durability, while a maximized gear design targets noise reduction. The unit carries a single intermittent/continuous torque rating and is compatible with the EX Drive shaft extension. Call us to confirm proper fit for your application.
