The Muncie A20-A1015-HX3IIPX or A20A1015HX3IIPX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically 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 the shift cover rotates a full 360 degrees for flexible installation positioning. An enlarged output shaft diameter adds durability under load, while reduced leak paths and extended-length mounting fasteners address common installation and maintenance concerns. The rotatable pump flange accommodates a range of hydraulic setups, and the unit is compatible with the EX Drive shaft extension. Three housing arrangements are available across the series.
