The Muncie A20-A1006-XX3BSPX or A20A1006XX3BSPX is a medium-duty, clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. It mounts via a 10-bolt pattern and features a shift cover that rotates a full 360 degrees, making installation orientation flexible regardless of your chassis configuration. A rotatable pump flange and increased clearance simplify pump hookups during installation. Tapered roller bearings and an enlarged output shaft diameter extend service life, while a proven clutch pack design and maximized gear geometry keep operation quiet. Three housing arrangements are available, and the unit accepts the EX Drive shaft extension. Call us to confirm the correct speed ratio and housing arrangement for your application.
