The Muncie A20-A1005-HX3IIUX or A20A1005HX3IIUX is a medium-duty, 10-bolt clutch shift power take-off from the A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible installation, and the rotatable pump flange further simplifies mounting in tight chassis configurations. Tapered roller bearings extend PTO service life, while the enlarged output shaft diameter adds durability under load. The gear set is optimized to keep noise low, leak paths are minimized by design, and three housing arrangements let you match the unit to your chassis layout. Extended-length PTO mounting fasteners and compatibility with the EX Drive shaft extension round out the installation options. Call us to confirm proper fit for your application.
