The Muncie A20-A1007-HX1CC or A20A1007HX1CC is a medium-duty, clutch shift power take-off from Muncie's A20 Series, engineered specifically for Allison 3000 and 4000 Series transmissions. The 10-bolt mounting pattern pairs with a rotatable pump flange and a shift cover that allows full 360-degree rotation, giving installers far more flexibility in tight cab-to-axle packaging. Tapered roller bearings extend service life, and the increased output shaft diameter handles higher-torque accessory loads. The proven clutch pack design carries a single intermittent and continuous torque rating, and three housing arrangements cover a broad range of truck configurations. The unit is also compatible with the EX Drive shaft extension. Call us to confirm the correct ratio and housing arrangement for your application.
