The Muncie A20-A1005-HX3BSPX or A20A1005HX3BSPX is a medium-duty, 10-bolt clutch shift power take-off from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible installation, and the rotatable pump flange simplifies hydraulic hookup. Tapered roller bearings extend PTO service life, while the increased output shaft diameter handles higher load demands. Reduced leak paths and maximized gear geometry keep noise and maintenance low. Three housing arrangements give installers layout flexibility, and extended-length mounting fasteners and compatibility with the EX Drive shaft extension round out the design. A genuine Muncie part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
