The Muncie A20-A1012-HX11XPX or A20A1012HX11XPX 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 with tapered roller bearings for extended service life, and an increased-diameter output shaft for added durability. A rotatable pump flange and a shift cover with 360-degree rotation simplify installation and positioning. Reduced leak paths and a maximized gear profile keep noise and fluid management in check. Three housing arrangements give you flexibility in mounting configuration, and compatibility with the EX Drive shaft extension broadens application options. Extended-length PTO mounting fasteners are included. Call us to confirm proper fit for your specific transmission and hydraulic setup.
