The Muncie A20-A1010-HH3BBPX or A20A1010HH3BBPX is a medium-duty, 10-bolt clutch shift power take-off designed specifically for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design with tapered roller bearings to extend PTO service life, and the shift cover rotates a full 360 degrees for flexible installation positioning. A rotatable pump flange and increased housing clearance simplify mounting, while extended-length PTO mounting fasteners and reduced leak paths address common field complaints. The enlarged output shaft diameter adds durability under load, and the gear set is optimized to keep noise down. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the correct housing arrangement and gear speed for your application.
