The Muncie A20-A1006-SX3X4BX (also referenced as A20A1006SX3X4BX) is a medium-duty, 10-bolt clutch shift power take-off engineered specifically 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 far more flexibility in tight mounting situations. Extended-length PTO mounting fasteners and increased housing clearance further simplify installation. Internally, tapered roller bearings protect the output shaft, and a proven clutch pack delivers a single intermittent/continuous torque rating across the speed range. The unit is also compatible with the Muncie EX Drive shaft extension. Call us to confirm proper fit for your application.
