The Muncie A20-A1012-XX1PSPX or A20A1012XX1PSPX is a medium-duty, 10-bolt clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. The A20 Series mounts with extended-length fasteners and offers three housing arrangements, so the unit can be positioned to suit a wide range of installations. A shift cover with 360-degree rotation and a rotatable pump flange give the installer real flexibility on tight engine bays. Tapered roller bearings and an increased-diameter output shaft address long-term durability, while the maximized gear profile keeps operating noise down. The design carries a single intermittent/continuous torque rating and is compatible with the EX Drive shaft extension. Call us to confirm proper fit for your application.
