The Muncie A20-A1006-HX3BB or A20A1006HX3BB is a 10-bolt clutch shift power takeoff built for Allison 3000 and 4000 series automatic transmissions. The shift cover rotates 360 degrees, and the pump flange is fully rotatable, giving installers flexibility in tight engine compartments. Three housing arrangements are available to suit different mounting configurations. Tapered roller bearings extend service life, and the increased output shaft diameter adds durability under sustained load. Torque ratings are unified across intermittent and continuous duty cycles. The unit is compatible with the EX Drive shaft extension. Extended-length PTO mounting fasteners and a reduced-leak-path design round out the build. Call us to confirm proper fit for your application.
