The Muncie A20-A1005-SX3BBPW or A20A1005SX3BBPW is a medium-duty, 10-bolt clutch shift power take-off from Muncie's A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, and the pump flange is rotatable as well, giving installers flexibility in tight mounting situations. Extended-length PTO mounting fasteners and increased housing clearance simplify installation. Tapered roller bearings and an increased-diameter output shaft extend service life, while a proven clutch pack design and maximized gear geometry keep noise down. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the right housing arrangement and output configuration for your application.
