The Muncie A20-A1015-HX3PBPW or A20A1015HX3PBPW is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series features a rotatable pump flange and a shift cover that allows 360-degree rotation, giving installers flexibility in mounting orientation. A proven clutch pack design and tapered roller bearings extend service life, while an increased-diameter output shaft adds durability under sustained loads. Reduced leak paths and maximized gear geometry keep noise low during operation. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension for added installation versatility.
