The Muncie A20-A1008-SX3X4PX-AP or A20A1008SX3X4PXAP is a medium-duty, 10-bolt clutch shift power takeoff from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees for flexible installation, and the rotatable pump flange simplifies hydraulic hookup. Tapered roller bearings extend service life, and the increased-diameter output shaft handles higher torque loads. The single intermittent/continuous torque rating simplifies application matching, and the unit ships in three available housing arrangements. Extended-length mounting fasteners and compatibility with the EX Drive shaft extension round out the installation options. Call us to confirm the right configuration for your chassis.
