The Muncie A20-A1006-HX1CBPW or A20A1006HX1CBPW is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design with tapered roller bearings to extend service life, and the shift cover rotates a full 360 degrees for flexible installation positioning. An increased output shaft diameter adds durability at the working end, while the rotatable pump flange and extended-length PTO mounting fasteners simplify fitment. Three housing arrangements are available across the series, and the unit is compatible with the Muncie EX Drive shaft extension. Reduced leak paths and a maximized gear design keep fluid contained and operating noise low. Call us to confirm the correct housing arrangement and ratio for your application.
