The Muncie A20-A1011-HX31XUS or A20A1011HX31XUS is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design with tapered roller bearings to extend service life, and carries a single intermittent/continuous torque rating that simplifies application planning. The shift cover rotates 360 degrees for flexible installation, and the pump flange is independently rotatable for pump plumbing alignment. An increased-diameter output shaft adds durability, and extended-length PTO mounting fasteners accommodate the 10-bolt bolt pattern. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension for setups requiring additional reach. Call us to confirm proper fit for your application.
