The Muncie A20-A1006-HH3BBPX or A20A1006HH3BBPX is a 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. Part of Muncie's A20 Series medium-duty PTO line, it features a rotatable pump flange and a shift cover with 360-degree rotation, giving installers flexibility in tight engine compartments. Tapered roller bearings and an increased-diameter output shaft extend service life, while a proven clutch pack design carries a single intermittent/continuous torque rating across the speed range. Three housing arrangements and compatibility with the EX Drive shaft extension add application versatility. Extended-length PTO mounting fasteners and reduced leak paths round out the design.
