The Muncie A20-A1007-HX5BABX or A20A1007HX5BABX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible mounting, and the pump flange is also fully rotatable to simplify hydraulic plumbing in tight installations. Tapered roller bearings extend PTO service life, and the increased-diameter output shaft adds durability under sustained load. Gear geometry is optimized to reduce noise in operation. Three housing arrangements are available, and the unit is compatible with the Muncie EX Drive shaft extension. Extended-length PTO mounting fasteners and increased installation clearance make chassis fitment straightforward. Call us to confirm the correct housing arrangement for your application.
