The Muncie A20-A1005-HX3BBPX-AP or A20A1005HX3BBPXAP is a 10-bolt clutch shift power takeoff built for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, giving installers flexibility in tight mounting situations, and the rotatable pump flange adds further positioning options. Tapered roller bearings extend PTO service life, and an increased output shaft diameter handles higher drive loads. The design incorporates three housing arrangements, making it adaptable across a range of vehicle configurations. Extended-length mounting fasteners, reduced leak paths, and compatibility with the EX Drive shaft extension round out a well-engineered package.
