The Muncie A20 Series power take-off, part number A20-A1005-HX3BBPX-XX or A20A1005HX3BBPXXX, is a medium-duty, 10-bolt clutch shift PTO engineered specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees, and a rotatable pump flange gives installers flexibility in mounting orientation. Extended-length PTO mounting fasteners and increased housing clearance simplify installation. Tapered roller bearings and an enlarged output shaft diameter are built into the design to extend service life, while a maximized gear profile reduces operating noise. Three housing arrangements are available, and the unit is compatible with the Muncie EX Drive shaft extension. Call us to confirm the right configuration for your application.
