The Muncie A20-A1005-XX3CBPW or A20A1005XX3CBPW is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design with tapered roller bearings for extended service life, and a rotatable pump flange paired with a 360-degree rotating shift cover to simplify installation and plumbing orientation. An increased-diameter output shaft adds durability under load, while the maximized gear design keeps noise low in operation. The unit carries a single intermittent/continuous torque rating, comes in three housing arrangements, and supports the EX Drive shaft extension for added flexibility. Extended-length PTO mounting fasteners and increased installation clearances are standard.
