The Muncie A20-A1008-HX3X4 or A20A1008HX3X4 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 rotates a full 360 degrees, making installation alignment straightforward. A rotatable pump flange and increased housing clearance further simplify the installation process. Tapered roller bearings and an increased-diameter output shaft are built in to extend service life, while a maximized gear design reduces operating noise. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the right configuration for your application.
