The Muncie A20-A1005-JX31XPX or A20A1005JX31XPX 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 with 360-degree rotation, so housing orientation can be tailored to the installation. A rotatable pump flange and increased clearance around the unit simplify fitment on tight chassis. The clutch pack design carries a single intermittent/continuous torque rating across the range, and tapered roller bearings are used throughout to extend service life. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension for additional reach. Call us to confirm the correct configuration for your application.
