The Muncie A20 Series power take-off A20-A1007-HX3BAPX or A20A1007HX3BAPX is a medium-duty, clutch-shift PTO designed specifically for Allison 3000 and 4000 Series transmissions, using a 10-bolt mounting pattern. The A20 Series ships with extended-length PTO mounting fasteners and a shift cover with 360-degree rotation, making installation easier in tight engine compartments. A rotatable pump flange and increased housing clearance add installation flexibility. Tapered roller bearings and an increased-diameter output shaft contribute to extended service life, while a proven clutch pack design and maximized gear geometry keep operating noise low.
