The Muncie A20-A1007-HX3CBBW or A20A1007HX3CBBW is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series carries a single intermittent/continuous torque rating across the available speed ratios, simplifying spec selection. A rotatable pump flange and shift cover with 360-degree rotation allow the housing to be positioned to suit tight installation spaces, while increased clearance around the unit eases the actual mounting process. Extended-length PTO mounting fasteners and three available housing arrangements give installers additional flexibility. The proven clutch pack design pairs with tapered roller bearings to extend service life, and an increased output shaft diameter adds durability at the drive connection. This unit is compatible with the EX Drive shaft extension. Available from Pro Gear and Transmission. Call us to confirm proper fit for your specific vehicle and transmission configuration.
