The Muncie A20-A1007-HX3IIPX or A20A1007HX3IIPX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series carries a single intermittent/continuous torque rating, simplifying spec selection, and the shift cover allows full 360-degree rotation for flexible mounting positions. A rotatable pump flange and three available housing arrangements make it adaptable across a range of truck configurations. Tapered roller bearings extend service life, and an increased output shaft diameter adds durability under sustained load. Extended-length PTO mounting fasteners and increased installation clearance reduce time on the job. The unit is also compatible with the EX Drive shaft extension. Call us to confirm proper fit for your application.
