The Muncie A20-A1006-XX3PBPX or A20A1006XX3PBPX is a medium-duty clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. It mounts via a 10-bolt pattern and features a shift cover that rotates 360 degrees, allowing flexible installation in tight engine compartments. A rotatable pump flange and increased housing clearance simplify pump alignment and mounting. Tapered roller bearings extend service life, and the increased output shaft diameter adds durability under load. The gear design is optimized to minimize noise, and reduced leak paths help maintain a clean installation. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the correct configuration for your application.
