The Muncie A20-A1006-SX31X or A20A1006SX31X is a medium-duty clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. Part of the Muncie A20 Series, it mounts via a 10-bolt interface and features a shift cover that rotates 360 degrees, making it adaptable to tight installation environments. A rotatable pump flange and extended-length PTO mounting fasteners further simplify fitment. The clutch pack design carries a single intermittent/continuous torque rating, and tapered roller bearings extend service life. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the correct housing and speed configuration for your application.
