The Muncie A20-A1008-HX5BBBX or A20A1008HX5BBBX 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 flexibility in tight mounting situations. Tapered roller bearings extend PTO service life, while an increased output shaft diameter adds durability under load. The proven clutch pack uses a single intermittent/continuous torque rating, simplifying spec selection. Three housing arrangements and compatibility with the EX Drive shaft extension give this unit broad installation flexibility. Reduced leak paths and a maximized gear profile keep noise low during operation. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
