The Muncie A20-A1008-HX5BSPX or A20A1008HX5BSPX is a medium-duty, 10-bolt clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. Part of Muncie's A20 Series, it features a rotatable pump flange and a shift cover with 360-degree rotation, both of which simplify installation and plumbing orientation. Tapered roller bearings and an increased-diameter output shaft extend service life, while a proven clutch pack design carries a single intermittent/continuous torque rating across the speed range. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Extended-length PTO mounting fasteners and reduced leak paths round out the design.
