The Muncie A20-A1007-HX5CCBX or A20A1007HX5CCBX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 Series and 4000 Series transmissions. The A20 Series is built around a proven clutch pack design with tapered roller bearings for extended service life and an increased-diameter output shaft for added durability. A rotatable pump flange and a shift cover with 360-degree rotation simplify installation and mounting flexibility. Three housing arrangements are available, and the unit carries a single intermittent/continuous torque rating across its speed range. Extended-length PTO mounting fasteners and increased installation clearance ease the fitment process. The unit is also compatible with the EX Drive shaft extension. Available from Pro Gear and Transmission. Call us to confirm the correct configuration for your application.
