The Muncie A20-A1008-H23IIPX or A20A1008H23IIPX 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 to extend service life, and an increased-diameter output shaft for added durability at the wheel end. A shift cover with 360-degree rotation and a rotatable pump flange simplify installation and pump alignment. Increased housing clearance and extended-length PTO mounting fasteners make the unit easier to fit in tight engine compartments. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Available from Pro Gear and Transmission.
