The Muncie A20 Series 10-bolt clutch shift power take-off, part number A20-A1015-HR1BBPX or A20A1015HR1BBPX, is a medium-duty PTO engineered specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible installation positioning, and the pump flange is also rotatable to suit different pump orientations. Tapered roller bearings support the output shaft, and the increased output shaft diameter adds durability under load. Three housing arrangements are available, and the unit carries a single intermittent/continuous torque rating across its speed range. Extended-length PTO mounting fasteners and increased installation clearance simplify fitting. The A20 series is also compatible with the Muncie EX Drive shaft extension.
