The Muncie A20-A1006-HX3PBPW or A20A1006HX3PBPW is a medium-duty, 10-bolt clutch shift power take-off from Muncie's A20 Series, engineered specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees and the pump flange is also rotatable, giving installers flexibility in tight engine compartments. Extended-length PTO mounting fasteners and increased clearance simplify the installation process. Tapered roller bearings extend service life, while the increased-diameter output shaft handles higher load demands. The proven clutch pack design carries a single intermittent/continuous torque rating, and the unit is compatible with the EX Drive shaft extension.
