The Muncie A20-A1010-HX1X4PX 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 360-degree rotation, giving installers considerably more flexibility during mounting. Extended-length PTO mounting fasteners and increased installation clearances reduce the time spent fitting the unit to the transmission. Tapered roller bearings and an increased-diameter output shaft address long-term durability, while a maximized gear design keeps noise down under load. The A20-A1010-HX1X4PX also supports three housing arrangements and is compatible with the EX Drive shaft extension. Call us to confirm the right configuration for your application.
