The Muncie A20-A1008-SX3BBPX or A20A1008SX3BBPX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. It mounts via a 10-bolt pattern and uses a proven clutch pack design with tapered roller bearings to extend service life. The shift cover rotates 360 degrees for flexible plumbing, and the rotatable pump flange adapts to multiple installation orientations. Three housing arrangements are available, and the unit accepts the EX Drive shaft extension for applications that require it. Extended-length PTO mounting fasteners and increased output shaft diameter address durability and ease of installation together. Call us to confirm proper fit for your application.
