The Muncie A20-A1010-RS11XPX (also referenced as A20A1010RS11XPX) is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series design incorporates a rotatable pump flange and a shift cover with 360-degree rotation, giving installers greater flexibility in tight mounting situations. Tapered roller bearings and an increased-diameter output shaft extend service life, while a maximized gear profile reduces operating noise. The unit carries a single intermittent/continuous torque rating, is available in three housing arrangements, and accepts the EX Drive shaft extension. Extended-length PTO mounting fasteners are included. Call us to confirm proper fit for your specific Allison transmission configuration.
