The Muncie A20-A1006-HX1ZBPX or A20A1006HX1ZBPX is a medium-duty, clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions, mounted via a 10-bolt pattern. The A20 Series uses a proven clutch pack design with tapered roller bearings for extended PTO service life and an increased-diameter output shaft for added durability under load. The shift cover rotates 360 degrees for flexible installation in tight cab configurations, and a rotatable pump flange accommodates a range of hydraulic setups. Three housing arrangements are available, and the unit is compatible with the Muncie EX Drive shaft extension. Extended-length PTO mounting fasteners and reduced leak paths simplify installation and long-term service. Call us to confirm proper fit for your application.
