The Muncie A20-A1012-XX1BSPX or A20A1012XX1BSPX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design with tapered roller bearings to extend service life, and features a shift cover with full 360-degree rotation so it can be positioned to clear chassis obstructions. The rotatable pump flange and extended-length PTO mounting fasteners simplify installation, while an increased output shaft diameter handles higher drive loads. Reduced leak paths and a maximized gear profile keep noise down in daily use. Three housing arrangements are available, and the unit accepts the EX Drive shaft extension. Call us to confirm proper fit for your application.
