The Muncie A20-A1012-HX1PB or A20A1012HX1PB is a medium-duty, 10-bolt clutch shift power takeoff engineered for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible installation positioning, and the rotatable pump flange adds further adaptability at the output end. Tapered roller bearings extend PTO service life, and an increased-diameter output shaft adds durability under load. The clutch pack uses a single intermittent/continuous torque rating, simplifying spec verification. Three housing arrangements are available, extended-length mounting fasteners ease installation, and the unit is compatible with the EX Drive shaft extension system. Call us to confirm the correct housing arrangement and ratio for your application.
