The Muncie A20 Series 10-bolt clutch shift power take-off, part number A20-A1005-HH1BAPX or A20A1005HH1BAPX, is a medium-duty PTO designed specifically for Allison 3000 and 4000 Series transmissions. The 360-degree rotatable shift cover and rotatable pump flange simplify installation in tight engine compartments, while extended-length PTO mounting fasteners and increased clearance reduce fitment headaches. Tapered roller bearings extend service life, and an increased-diameter output shaft handles higher torque demands. The proven clutch pack delivers a single intermittent/continuous torque rating across three available housing arrangements. The unit is also compatible with the EX Drive shaft extension.
