The Muncie A20-A1015-HX1X4 or A20A1015HX1X4 is a medium-duty, 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. The shift cover rotates 360 degrees for flexible installation positioning, and a rotatable pump flange simplifies hydraulic hookup. Three housing arrangements and extended-length PTO mounting fasteners broaden mounting options. The unit carries a single intermittent/continuous torque rating and is compatible with the EX Drive shaft extension.
