The Muncie A20-A1011-HX3PBPX or A20A1011HX3PBPX is a medium-duty, 10-bolt clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design with tapered roller bearings for extended service life, and an increased-diameter output shaft for added durability. The rotatable pump flange and a shift cover with 360-degree rotation simplify installation and pump mounting. Reduced leak paths and a maximized gear profile keep operation quiet. Three housing arrangements are available, and the unit is compatible with the Muncie EX Drive shaft extension. Extended-length PTO mounting fasteners and increased installation clearance round out the design. Call us to confirm proper fit for your application.
