The Muncie A20-A1005-SX5BBPX or A20A1005SX5BBPX is a medium-duty, clutch shift power take-off designed specifically for Allison 3000 and 4000 Series transmissions, mounted via a 10-bolt pattern. The A20 Series uses a proven clutch pack with tapered roller bearings to extend service life, and the shift cover rotates a full 360 degrees for flexible installation routing. The rotatable pump flange and increased housing clearances simplify mounting, while extended-length PTO mounting fasteners and an enlarged output shaft diameter add durability at the wheel end. Three housing arrangements are available, and the unit is compatible with the Muncie EX Drive shaft extension. Call us to confirm proper fit for your application.
