The Muncie A20-A1008-HX3BBUS or A20A1008HX3BBUS is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, and the pump flange is rotatable, giving installers flexibility in tight engine compartments. Extended-length PTO mounting fasteners and increased clearance simplify installation. Tapered roller bearings extend service life, and an increased-diameter output shaft adds durability at the drive end. The A20 series carries a single intermittent/continuous torque rating and is available in three housing arrangements, making it adaptable across a range of medium-duty vocational applications. Compatible with the Muncie EX Drive shaft extension. Call us to confirm proper fit for your application.
