The Muncie A20-A1012-HX3X4PX or A20A1012HX3X4PX 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 backed by tapered roller bearings for extended service life. A rotatable pump flange and shift cover with 360-degree rotation simplify installation and plumbing layout. The increased output shaft diameter adds durability, while extended-length PTO mounting fasteners and increased housing clearance make fitment more straightforward. Reduced leak paths and a maximized gear profile keep noise and fluid management in check. The unit is also compatible with the Muncie EX Drive shaft extension for added installation flexibility. Call us to confirm proper fit for your specific application.
