The Muncie A20-A1006-HX1BBBX or A20A1006HX1BBBX is a 10-bolt clutch shift power takeoff designed for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, and the pump flange is independently rotatable, giving installers significant flexibility during mounting. Three housing arrangements are available to suit different installation requirements. Tapered roller bearings extend PTO service life, and an enlarged output shaft diameter adds durability at higher torque demands. Gear geometry is optimized for noise reduction, and leak paths are minimized across the assembly. The unit accepts the EX Drive shaft extension and ships with extended-length PTO mounting fasteners. Call us to confirm the correct configuration for your application.
