The Muncie A20-A1010-XX31XPX or A20A1010XX31XPX is a medium-duty, 10-bolt clutch shift power take-off designed specifically for Allison 3000 and 4000 Series transmissions. The A20 Series carries a single intermittent/continuous torque rating and is available in three housing arrangements, giving installers flexibility for tight installations. A shift cover with 360-degree rotation and a rotatable pump flange simplify mounting and accessory alignment. Tapered roller bearings and an increased-diameter output shaft extend service life, while maximized gear geometry keeps noise down. The unit is also compatible with the Muncie EX Drive shaft extension. Call us to confirm proper fit for your application.
