The Muncie A20-A1012-HX31X or A20A1012HX31X is a medium-duty, clutch-shift power take-off from Muncie's A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. It mounts via a 10-bolt pattern and features a shift cover with 360-degree rotation, letting you position the actuator where the installation demands. A rotatable pump flange and increased housing clearance simplify installation in tight bays. Tapered roller bearings and an increased-diameter output shaft address long-term durability, while a maximized gear profile reduces operating noise. Three housing arrangements are available, and the unit is compatible with Muncie's EX Drive shaft extension. Call us to confirm proper fit for your application.
