The Muncie A20-A1005-HX3BBBX or A20A1005HX3BBBX 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 and tapered roller bearings to extend service life, while the shift cover rotates a full 360 degrees for flexible installation. A rotatable pump flange, extended-length PTO mounting fasteners, and increased clearance simplify fitment. The output shaft diameter is sized for added durability, and maximized gear geometry keeps noise low. Three housing arrangements are available, and the unit accepts the EX Drive shaft extension. Call us to confirm the correct configuration for your application.
