The Muncie A20-A1006-HX3CB or A20A1006HX3CB is a medium-duty, clutch shift power take-off from the Muncie A20 Series, designed for Allison 3000 and 4000 Series transmissions. The 10-bolt mounting pattern pairs with a shift cover that rotates 360 degrees for flexible installation positioning, while the rotatable pump flange simplifies hydraulic plumbing. A proven clutch pack design and tapered roller bearings contribute to extended service life, and the increased output shaft diameter adds durability under load. Three housing arrangements give installers options for tight engine compartments, and the unit is compatible with the EX Drive shaft extension.
