The Muncie A20-A1007-HX5BB or A20A1007HX5BB is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series design centers on a single intermittent/continuous torque rating across all speeds, simplifying spec work for fleet and vocational applications. A shift cover allowing 360-degree rotation and a rotatable pump flange give installers real flexibility in mounting orientation, while extended-length PTO mounting fasteners and increased housing clearance reduce installation time. Tapered roller bearings and an enlarged output shaft diameter extend service life, and a maximized gear profile keeps operating noise low. The unit is also compatible with the EX Drive shaft extension. Call us to confirm proper fit for your application.
