The Muncie A20-A1012-HX3IIPX or A20A1012HX3IIPX is a 10-bolt clutch shift power takeoff built for Allison 3000 and 4000 series transmissions. The shift cover rotates 360 degrees, and the pump flange is also rotatable, giving installers genuine flexibility in tight mounting situations. Extended-length PTO mounting fasteners and increased clearance simplify installation. Tapered roller bearings support long service life, while the increased output shaft diameter adds durability at the output end. The gear design is optimized to minimize noise, and reduced leak paths keep fluids where they belong. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the right housing arrangement and gear ratio for your application.
