The Muncie A20-A1006-HR1BB or A20A1006HR1BB is a medium-duty, clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. Part of Muncie's A20 Series, it mounts via a 10-bolt interface and ships in three housing arrangements to fit a range of installation configurations. The shift cover rotates 360 degrees, and the pump flange is also rotatable, giving technicians real flexibility during installation. Tapered roller bearings extend service life, a proven clutch pack design delivers a single intermittent/continuous torque rating across the speed range, and the enlarged output shaft diameter adds durability under sustained loads. The unit is compatible with the EX Drive shaft extension. Call us to confirm the right housing arrangement and ratio for your application.
