The Muncie A20-A1005-HX3X4 or A20A1005HX3X4 is a medium-duty, 10-bolt clutch shift power takeoff engineered for Allison 3000 and 4000 Series transmissions. The A20 Series design centers on a proven clutch pack with tapered roller bearings for extended service life and an increased output shaft diameter for added durability. A rotatable pump flange and shift cover with 360-degree rotation simplify mounting and plumbing layout in tight installations. Increased clearance around the housing eases bolt-up, and extended-length PTO mounting fasteners are included. The unit carries a single intermittent/continuous torque rating, comes in three housing arrangements, and is compatible with the Muncie EX Drive shaft extension.
