The Muncie A20-A1010-HR3X4PX or A20A1010HR3X4PX is a medium-duty, clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. Part of the A20 Series, it features a shift cover allowing 360-degree rotation and a rotatable pump flange, both of which simplify installation and pump positioning. Tapered roller bearings extend service life, and the increased-diameter output shaft adds durability under load. Reduced leak paths and a maximized gear design keep operation quieter than earlier designs. The unit supports three housing arrangements and is compatible with the EX Drive shaft extension.
