The Muncie A20-A1006-HX5ZBPX or A20A1006HX5ZBPX is a medium-duty, 10-bolt clutch shift power takeoff engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series ships with extended-length PTO mounting fasteners and increased output shaft diameter for durability under sustained load. A shift cover with 360-degree rotation and a rotatable pump flange simplify installation and plumbing layout, while increased housing clearance eases fitting in tighter engine compartments. Reduced leak paths and a maximized gear profile address noise and fluid management. Three housing arrangements and compatibility with the EX Drive shaft extension give installers flexibility across chassis configurations. Call us to confirm proper fit for your application.
