Muncie part number A20-A1007-S21BBPX or A20A1007S21BBPX is a medium-duty, 10-bolt clutch shift power takeoff from the Muncie A20 Series, designed for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, and the rotatable pump flange gives you flexibility in mounting orientation. A proven clutch pack design, tapered roller bearings, and an increased-diameter output shaft work together to extend service life. Extended-length PTO mounting fasteners and increased clearance simplify installation. The unit is compatible with the EX Drive shaft extension and is available in three housing arrangements.
