The Muncie A20-A1011-HX3BSPX or A20A1011HX3BSPX is a medium-duty, clutch shift power take-off from the Muncie A20 Series, designed for Allison 3000 and 4000 Series transmissions via a 10-bolt mount. The A20 Series features a rotatable pump flange and a shift cover with 360-degree rotation, making installation and plumbing routing significantly more flexible in tight cab-chassis applications. Tapered roller bearings extend service life, and an increased output shaft diameter adds durability under load. The proven clutch pack design carries a single intermittent/continuous torque rating across supported speeds. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the right configuration for your specific application.
