The Muncie A20-A1007-HX31XPX or A20A1007HX31XPX is a 10-bolt clutch shift power takeoff designed for Allison transmissions. The shift cover rotates 360 degrees, and the pump flange is also rotatable, giving installers flexibility in tight engine bays. Tapered roller bearings extend PTO service life, and the increased output shaft diameter adds durability under sustained load. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Extended-length mounting fasteners, reduced leak paths, and a gear design optimized for noise reduction round out the specification. Sold by Pro Gear and Transmission.
