The Muncie A20-A1010-HX3ZBPX or A20A1010HX3ZBPX is a medium-duty, 10-bolt clutch shift power take-off from the Muncie A20 Series, engineered specifically for Allison 3000 and 4000 Series transmissions. The clutch pack design uses tapered roller bearings to extend PTO service life, and the increased output shaft diameter adds durability under sustained loads. A 360-degree rotating shift cover and rotatable pump flange give installers flexibility in tight engine compartments, while extended-length mounting fasteners and increased housing clearance simplify the installation. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension for added application flexibility. Call us to confirm proper fit for your specific transmission and truck configuration.
