The Muncie A20-A1015-XX1PBPX or A20A1015XX1PBPX is a medium-duty, 10-bolt clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design with tapered roller bearings for extended service life, and a shift cover that rotates 360 degrees for flexible installation positioning. The rotatable pump flange and increased housing clearance simplify mounting, while extended-length PTO mounting fasteners and reduced leak paths address common field complaints. The enlarged output shaft diameter adds durability under sustained loads, and the maximized gear design keeps operating noise down. Three housing arrangements are available, and the unit is compatible with Muncie's EX Drive shaft extension. Call us to confirm the correct ratio and housing configuration for your application.
