The Muncie A20-A1006-SX5CBPW or A20A1006SX5CBPW is a medium-duty, 10-bolt clutch shift power take-off from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees to accommodate varying installation angles, and the rotatable pump flange adds further flexibility during mounting. Extended-length PTO mounting fasteners and increased clearance around the unit simplify installation in tight engine bays. Tapered roller bearings extend service life, and the enlarged output shaft diameter adds durability under sustained load. Gear geometry is optimized to minimize noise in operation. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm proper fit for your application.
