The Muncie A20-A1008-SX3X4PX or A20A1008SX3X4PX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series design centers on a proven clutch pack with tapered roller bearings for extended service life, an increased-diameter output shaft for greater durability, and a shift cover that rotates a full 360 degrees for flexible installation. A rotatable pump flange and increased clearance around the unit simplify mounting in tight chassis configurations. Extended-length PTO mounting fasteners and reduced leak paths are built into the design. The unit is compatible with the EX Drive shaft extension and is sold by Pro Gear and Transmission.
