The Muncie A20-A1008-HX3PBPX or A20A1008HX3PBPX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design with tapered roller bearings to extend service life, and the shift cover rotates a full 360 degrees for flexible installation positioning. A rotatable pump flange and increased component clearances simplify mounting, while extended-length PTO mounting fasteners and three available housing arrangements accommodate a range of truck configurations. The increased output shaft diameter adds durability under sustained loads, and the gear geometry is optimized to reduce operating noise. The unit carries a single intermittent/continuous torque rating and is compatible with the Muncie EX Drive shaft extension. Call us to confirm proper fit for your application.
