The Muncie A20-A1007-HH3BBPX or A20A1007HH3BBPX is a medium-duty, 10-bolt clutch shift power take-off designed for Allison 3000 and 4000 series transmissions. The shift cover rotates a full 360 degrees, and the pump flange is also rotatable, giving installers flexibility in tight engine compartments. Three housing arrangements are available within the A20 series, and the unit is compatible with the EX Drive shaft extension. Extended-length PTO mounting fasteners and increased output shaft diameter contribute to long-term durability at the wheel end. Tapered roller bearings support extended service life, and a maximized gear design keeps operating noise down. Call us to confirm the correct housing arrangement and output configuration for your application.
