The Muncie A20 Series Power Take-Off, part number A20-A1011-HH3PBPX or A20A1011HH3PBPX, is a medium-duty clutch shift PTO designed for Allison 3000 and 4000 Series transmissions. The 10-bolt mounting interface pairs with a shift cover that rotates 360 degrees, giving installers flexibility in tight chassis layouts. A rotatable pump flange and extended-length PTO mounting fasteners further simplify installation. Internally, tapered roller bearings extend service life, an enlarged output shaft diameter adds durability, and the gear profile is shaped to minimize noise. The design carries a single intermittent/continuous torque rating and is compatible with the Muncie EX Drive shaft extension. Three housing arrangements are available to suit different installation requirements. Call us to confirm the right configuration for your application.
