The Muncie A20-A1007-HR1BBPW or A20A1007HR1BBPW is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series mounts with extended-length fasteners and a shift cover that rotates a full 360 degrees, giving technicians flexibility when routing controls in tight installations. A rotatable pump flange and increased housing clearance simplify initial fit-up. Tapered roller bearings extend PTO service life, and the enlarged output shaft diameter adds durability under sustained load. The proven clutch pack design carries a single intermittent and continuous torque rating across all speed options, and three housing arrangements let you match the unit to available mounting positions. The series is also compatible with the Muncie EX Drive shaft extension. Call us to confirm the right configuration for your application.
