The Muncie A20-A1010-HX3BBPX-XX or A20A1010HX3BBPXXX 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 an increased-diameter output shaft for added durability. A 360-degree rotatable shift cover and rotatable pump flange allow flexible installation in tight engine compartments, while extended-length PTO mounting fasteners and increased housing clearance simplify the fit-up process. The design incorporates reduced leak paths and a maximized gear profile for quieter operation. Three housing arrangements are offered, and the unit is compatible with the EX Drive shaft extension.
