The Muncie A20-A1006-HX11X or A20A1006HX11X is a medium-duty, 10-bolt clutch shift power take-off designed specifically for Allison 3000 and 4000 Series transmissions. It mounts via a 10-bolt pattern and uses a proven clutch pack for engagement. The shift cover allows 360-degree rotation, giving the installer flexibility in routing the actuation line. A rotatable pump flange adds further positioning freedom. Tapered roller bearings are used throughout to extend service life, and the increased-diameter output shaft adds durability at the drive end. The unit carries a single intermittent and continuous torque rating, comes in three housing arrangements, and is compatible with the EX Drive shaft extension.
