The Muncie A20-A1006-HX3PBPX or A20A1006HX3PBPX is a 10-bolt clutch shift power takeoff designed for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, and the pump flange is independently rotatable, giving installers significant flexibility in tight cab or chassis configurations. Increased clearance around the housing simplifies installation, while extended-length mounting fasteners help with alignment. Tapered roller bearings support the output shaft for longer service life, and the enlarged output shaft diameter adds durability under sustained drive loads. The gear design is optimized to minimize operating noise. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the right arrangement for your application.
