The Muncie A20-A1006-HX3X4PX or A20A1006HX3X4PX is a medium-duty, 10-bolt clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design with tapered roller bearings for extended service life. The shift cover rotates 360 degrees, and the rotatable pump flange simplifies mounting in tight installations. Increased output shaft diameter adds durability, while extended-length PTO mounting fasteners and reduced leak paths address common field complaints. The unit is compatible with the EX Drive shaft extension and is available in three housing arrangements. Call us to confirm the correct housing and ratio for your application.
