The Muncie A20-A1006-HX5PBBX or A20A1006HX5PBBX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 series transmissions. The A20 Series design incorporates tapered roller bearings for extended service life, a proven clutch pack, and a shift cover with 360-degree rotation to simplify installation routing. The rotatable pump flange and three available housing arrangements give technicians flexibility at the mount point, while extended-length PTO mounting fasteners and increased clearance cut installation time. An enlarged output shaft diameter handles higher drive loads, and the maximized gear profile reduces operating noise. The unit is also compatible with the EX Drive shaft extension.
