The Muncie A20-A1007-SX3CBPW or A20A1007SX3CBPW is a medium-duty, clutch shift power takeoff designed specifically for Allison 3000 and 4000 Series transmissions. It mounts via a 10-bolt pattern and uses a proven clutch pack design with tapered roller bearings to extend service life. The shift cover rotates 360 degrees, and the rotatable pump flange simplifies installation routing. An increased-diameter output shaft adds durability, while the maximized gear design reduces operating noise. Three housing arrangements and extended-length PTO mounting fasteners give installers flexibility. The unit is also compatible with the EX Drive shaft extension.
