The Muncie A20-A1005-HX5BSPX or A20A1005HX5BSPX is a medium-duty, clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. It mounts via a 10-bolt pattern and features a shift cover that rotates 360 degrees, giving installers full flexibility in routing shift controls. A rotatable pump flange and extended-length PTO mounting fasteners simplify installation in tight chassis. Tapered roller bearings extend service life, and the increased-diameter output shaft handles higher drivetrain loads. The proven clutch pack carries a single intermittent/continuous torque rating across all speed ratios. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the correct configuration for your application.
