The Muncie A20-A1007-SX31XPX or A20A1007SX31XPX is a medium-duty, clutch-shift power take-off built for Allison 3000 and 4000 Series transmissions. It mounts via a 10-bolt pattern and features a shift cover with 360-degree rotation and a rotatable pump flange, giving installers more flexibility in tight bays. Tapered roller bearings extend service life, and an increased-output-shaft diameter adds durability under sustained load. The design uses extended-length PTO mounting fasteners and carries increased installation clearance. It supports three housing arrangements and is compatible with the Muncie EX Drive shaft extension. Single intermittent/continuous torque rating simplifies application planning. Call us to confirm proper fit for your application.
