The Muncie A20-A1007-HX1X4PX or A20A1007HX1X4PX is a medium-duty, 10-bolt clutch shift power takeoff engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series features a shift cover with 360-degree rotation, giving installers flexibility in tight chassis configurations, and a rotatable pump flange to simplify hydraulic hookup. Tapered roller bearings extend service life, while an increased-diameter output shaft raises durability under continuous load. The clutch pack carries a single intermittent and continuous torque rating, and the gear set is optimized to minimize noise. Three housing arrangements are available within the series, and the unit accepts the Muncie EX Drive shaft extension. Extended-length PTO mounting fasteners are included.
