The Muncie A20-A1007-HR3BB or A20A1007HR3BB is a medium-duty, clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. It mounts on a 10-bolt pad and features a shift cover with 360-degree rotation, so housing orientation can be adapted to fit tight chassis installations. The rotatable pump flange and increased clearance around the unit simplify installation. Tapered roller bearings and an enlarged output shaft diameter extend service life, while a maximized gear design reduces operating noise. The unit carries a single intermittent/continuous torque rating and is available in three housing arrangements. It is also compatible with the EX Drive shaft extension.
