The Muncie A20-A1005-HX1BBBX or A20A1005HX1BBBX is a medium-duty, 10-bolt clutch shift power take-off engineered 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 a maximized gear profile to reduce operating noise. The shift cover rotates 360 degrees for flexible installation positioning, while the rotatable pump flange and increased housing clearance simplify pump fitment. An increased output shaft diameter adds durability at the drive end, and extended-length PTO mounting fasteners are included. Three housing arrangements are available, and the unit is compatible with the Muncie EX Drive shaft extension. Call us to confirm the correct configuration for your application.
