The Muncie A20-A1005-SX5CBPW or A20A1005SX5CBPW is a medium-duty, 10-bolt clutch shift power takeoff engineered for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design with tapered roller bearings to extend PTO service life, and an increased-diameter output shaft for added durability. The shift cover rotates 360 degrees, and the rotatable pump flange simplifies installation in tight engine compartments. Reduced leak paths and a maximized gear profile keep noise low in continuous operation. Three housing arrangements are available, and the unit accepts the EX Drive shaft extension. Call us to confirm the correct housing arrangement and ratio for your application.
