The Muncie A20-A1008-JX3IIPW or A20A1008JX3IIPW is a medium-duty, clutch-shift power take-off from the Muncie A20 Series, designed specifically 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 engine compartments. A rotatable pump flange and extended-length PTO mounting fasteners contribute to easier, lower-clearance installations. Tapered roller bearings and an increased-diameter output shaft address long-term durability, while a maximized gear design reduces operating noise. The unit carries a single intermittent/continuous torque rating and is available in three housing arrangements. It is also compatible with the EX Drive shaft extension. Call us to confirm proper fit for your specific application.
