The Muncie A20-A1006-XX3BBPX or A20A1006XX3BBPX is a medium-duty, clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. It mounts via a 10-bolt pattern and features a shift cover with 360-degree rotation for flexible installation positioning, along with a rotatable pump flange and increased housing clearance that simplify mounting in tight bays. Tapered roller bearings extend service life, and an increased output shaft diameter adds durability at the drive end. The gear set is optimized for reduced noise, leak paths are minimized by design, and the unit carries a single intermittent/continuous torque rating across speed positions. Three housing arrangements and compatibility with the EX Drive shaft extension add application flexibility. Available from Pro Gear and Transmission. Call us to confirm the right configuration for your transmission and application.
