The Muncie A20-A1012-SX1X4PX or A20A1012SX1X4PX is a medium-duty, 10-bolt clutch shift power take-off engineered 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 the shift cover rotates a full 360 degrees for flexible installation in tight engine compartments. A rotatable pump flange, increased output shaft diameter, and extended-length PTO mounting fasteners address the common installation and durability pain points found on older clutch-shift designs. Reduced leak paths and a maximized gear profile keep noise and fluid loss in check. Compatible with the EX Drive shaft extension. Three housing arrangements are available.
