The Muncie A20-A1007-HX1CBPX or A20A1007HX1CBPX is a medium-duty, 10-bolt clutch shift power take-off engineered 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 designed to simplify installation in tight engine compartments. Tapered roller bearings and an increased-diameter output shaft extend service life under demanding hydraulic and mechanical loads. The proven clutch pack carries a single intermittent/continuous torque rating, and the maximized gear geometry reduces operating noise. Three housing arrangements are available, and the unit accepts the EX Drive shaft extension. Extended-length PTO mounting fasteners and reduced leak paths round out the design.
