The Muncie A20-A1007-HX3BBBX or A20A1007HX3BBBX is a medium-duty, 10-bolt clutch shift power take-off from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover allows 360-degree rotation, giving installers flexibility in tight engine compartments, and the rotatable pump flange further simplifies plumbing. Tapered roller bearings extend PTO service life, and the increased output shaft diameter adds durability under load. Three housing arrangements are available to suit different mounting configurations, and the unit is compatible with the EX Drive shaft extension. Extended-length PTO mounting fasteners and increased installation clearance make initial fitment straightforward. Call us to confirm the correct ratio and housing arrangement for your application.
