The Muncie A20-A1007-HX3II or A20A1007HX3II is a medium-duty, 10-bolt clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. The A20 Series features a rotatable pump flange and a shift cover that allows 360-degree rotation, both of which simplify installation and plumbing layout. Tapered roller bearings extend service life, and the increased output shaft diameter adds durability under sustained load. The proven clutch pack carries a single intermittent/continuous torque rating across the operating range, and the gear profile is engineered to minimize noise. 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.
