The Muncie A20-A1012-HX1CBPX or A20A1012HX1CBPX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series mounts via extended-length PTO fasteners and accepts three housing arrangements, giving installers flexibility in tight bays. A shift cover with 360-degree rotation and a rotatable pump flange simplify plumbing and alignment. Tapered roller bearings extend service life, and the increased-diameter output shaft handles higher drive loads. Gear geometry is optimized for reduced noise, and reduced leak paths lower long-term maintenance demands. The unit carries a single intermittent/continuous torque rating and is compatible with the Muncie EX Drive shaft extension. Call us to confirm proper fit for your application.
