The Muncie A20 Series power take-off, part number A20-A1008-H23BBPX or A20A1008H23BBPX, is a medium-duty, 10-bolt clutch shift PTO designed for Allison 3000 and 4000 Series transmissions. The A20 Series carries a single intermittent/continuous torque rating, simplifying spec selection. A rotatable pump flange and a shift cover with 360-degree rotation give installers flexibility in tight bays. Tapered roller bearings and an increased-diameter output shaft address long-term durability, while a maximized gear design reduces operating noise. The unit accommodates three housing arrangements and is compatible with the Muncie EX Drive shaft extension. Call us to confirm proper fit for your application.
