The Muncie A20-A1006-SX5BBPX or A20A1006SX5BBPX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series features a rotatable pump flange and a shift cover with 360-degree rotation, both aimed at simplifying installation in tight engine compartments. Tapered roller bearings extend PTO service life, while an increased-diameter output shaft adds durability under sustained load. The proven clutch pack design carries a single intermittent/continuous torque rating, eliminating guesswork when spec'ing the unit for a given application. Three housing arrangements and compatibility with the EX Drive shaft extension give spec'ers meaningful flexibility. Available from Pro Gear and Transmission.
