The Muncie A20 Series 10-Bolt Clutch Shift Power Take-Off, part number A20-A1009-HX1PBPX or A20A1009HX1PBPX, is a medium-duty clutch shift PTO engineered specifically for Allison 3000 and 4000 Series transmissions. The rotatable pump flange and shift cover allow 360-degree rotation, giving technicians real flexibility during installation. Increased clearance around the unit eases fitment, and extended-length PTO mounting fasteners simplify the bolt-up. Tapered roller bearings and an increased-diameter output shaft extend service life, while a maximized gear design keeps operating noise down. The unit carries a single intermittent/continuous torque rating and is compatible with the Muncie EX Drive shaft extension. Three housing arrangements are available across the A20 Series.
