The Muncie A20-A1008-JX1IIPX or A20A1008JX1IIPX is a medium-duty, 10-bolt clutch shift power take-off engineered 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 the shift cover rotates a full 360 degrees to simplify installation in tight bays. A rotatable pump flange, increased output shaft diameter, and extended-length PTO mounting fasteners add installation flexibility. The gear set is optimized for reduced noise, leak paths are minimized, and three housing arrangements are available. The unit is also compatible with the EX Drive shaft extension.
