The Muncie A20-A1005-HX3CB or A20A1005HX3CB is a medium-duty clutch shift power takeoff from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions via a 10-bolt mounting. The shift cover rotates 360 degrees to simplify installation routing, and the rotatable pump flange gives additional flexibility for hydraulic connections. Tapered roller bearings extend service life, while an increased output shaft diameter adds durability under load. The gear set is designed to minimize noise, and reduced leak paths keep the unit clean in service. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the correct housing arrangement and ratio for your application.
