The Muncie A20-A1009-HX1IIPX or A20A1009HX1IIPX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically 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 loads. The shift cover rotates 360 degrees and the pump flange is fully rotatable, giving installers flexibility in tight mounting situations. Increased housing clearance and extended-length PTO mounting fasteners simplify installation. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. A single intermittent/continuous torque rating applies across the speed range. Available from Pro Gear and Transmission - call us to confirm the correct configuration for your application.
