The Muncie A20-A1010-HX3IIPX or A20A1010HX3IIPX is a medium-duty, 10-bolt clutch shift power take-off engineered 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 flexibility in tight engine compartments. Tapered roller bearings extend service life, and an increased-diameter output shaft handles higher torque loads. Extended-length PTO mounting fasteners and increased installation clearance simplify the installation process. The unit is also compatible with the Muncie EX Drive shaft extension, and three housing arrangements are available to suit different mounting needs.
