The Muncie A20 Series power take-off A20-A1007-HX3X4PN or A20A1007HX3X4PN is a medium-duty, 10-bolt clutch shift PTO designed for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design and tapered roller bearings to extend service life, while an increased output shaft diameter adds durability under sustained load. A rotatable pump flange and a shift cover with 360-degree rotation simplify installation and plumbing layout. Extended-length PTO mounting fasteners, increased housing clearance, and reduced leak paths are built into the design. The unit is compatible with the Muncie EX Drive shaft extension and supports three housing arrangements. Available from Pro Gear and Transmission.
