The Muncie A20-A1010-HX3CB or A20A1010HX3CB is a medium-duty, clutch shift power take-off from the Muncie A20 Series, designed for Allison 3000 and 4000 Series transmissions. The 10-bolt mounting pattern pairs with a shift cover that allows 360-degree rotation, giving installers flexibility in tight bays. A rotatable pump flange and increased housing clearance simplify installation. Tapered roller bearings extend service life, and the enlarged output shaft diameter handles higher drive loads. The single intermittent/continuous torque rating keeps spec selection straightforward, and three housing arrangements let it fit a range of truck configurations. The unit is also compatible with the EX Drive shaft extension. Call us to confirm proper fit for your application.
