The Muncie A20-A1011-HX1BBPX or A20A1011HX1BBPX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series design centers on a rotatable pump flange and a shift cover with full 360-degree rotation, giving installers considerably more flexibility in tight mounting situations. Tapered roller bearings extend service life at the output, and the increased-diameter output shaft handles higher driveline loads. Gear geometry is optimized for noise reduction, and reduced leak paths cut maintenance callbacks. Three housing arrangements cover a range of installations, and the unit is compatible with the EX Drive shaft extension. Available from Pro Gear and Transmission.
