The Muncie A20-A1006-HX3BAPX or A20A1006HX3BAPX is a medium-duty, 10-bolt clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible mounting, and the pump flange is independently rotatable to simplify plumbing. Tapered roller bearings extend PTO service life, while the increased output shaft diameter adds durability under sustained load. Three housing arrangements are available within the A20 Series, and the unit is compatible with the EX Drive shaft extension for added installation flexibility. Gear geometry is maximized for noise reduction, and extended-length PTO mounting fasteners ease installation. A genuine Muncie part, available from Pro Gear and Transmission.
