The Muncie A20-A1012-XX31XPX or A20A1012XX31XPX is a medium-duty, clutch shift power take-off built specifically for Allison 3000 and 4000 Series transmissions. It mounts via a 10-bolt pattern and features a rotatable pump flange, a shift cover with 360-degree rotation, and increased clearance for easier installation. Tapered roller bearings extend service life, while an increased-diameter output shaft improves durability. The proven clutch pack design carries a single intermittent/continuous torque rating, simplifying application selection. Three housing arrangements let you match the unit to your installation geometry, and extended-length PTO mounting fasteners and compatibility with the EX Drive shaft extension add installation flexibility.
