The Muncie A20-A1011-SX31XPX or A20A1011SX31XPX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design with tapered roller bearings to extend service life, and the shift cover rotates 360 degrees for flexible installation. The rotatable pump flange, increased output shaft diameter, and extended-length PTO mounting fasteners reduce installation complexity and improve durability at the output end. Gear geometry is optimized to minimize operating noise, and reduced leak paths keep fluid where it belongs. The unit also supports the EX Drive shaft extension. Call us to confirm proper fit for your specific transmission application.
