The Muncie A20-A1007-HX3PBBX or A20A1007HX3PBBX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible mounting, and the rotatable pump flange adapts to a wide range of hydraulic setups. Tapered roller bearings extend service life, while an enlarged output shaft diameter adds durability under sustained loads. The gear set is designed to minimize operating noise, and reduced leak paths simplify long-term maintenance. Three housing arrangements are available, extended-length mounting fasteners ease installation, and the unit is compatible with the Muncie EX Drive shaft extension.
