The Muncie A20-A1008-HX3BSPX or A20A1008HX3BSPX is a medium-duty, 10-bolt clutch shift power takeoff from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible installation, and the rotatable pump flange simplifies hydraulic plumbing. Tapered roller bearings and an increased-diameter output shaft extend service life, while the maximized gear design keeps noise down under load. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Extended-length PTO mounting fasteners and increased installation clearance round out a design built to go in faster and stay in longer. Call us to confirm proper fit for your application.
