The Muncie A20-A1015-HX3PB or A20A1015HX3PB is a medium-duty, clutch shift power take-off from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. It mounts via a 10-bolt pattern and includes a shift cover with 360-degree rotation, giving installers flexibility on tight firewall clearances. The rotatable pump flange, extended-length PTO mounting fasteners, and increased clearance around the housing all simplify installation compared to earlier designs. Tapered roller bearings support the output shaft, and the increased output shaft diameter adds durability under sustained load. The unit carries a single intermittent/continuous torque rating and is compatible with the EX Drive shaft extension. Three housing arrangements are available within the series. Call Pro Gear and Transmission to confirm the correct arrangement for your specific application.
