The Muncie A20-A1008-JX31XPX or A20A1008JX31XPX is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design with tapered roller bearings for extended PTO service life. The shift cover allows 360-degree rotation, and the pump flange is fully rotatable to simplify installation orientation. An increased-diameter output shaft adds durability under load, while reduced leak paths and maximized gear geometry keep noise and fluid loss in check. Three housing arrangements are available, and the unit accepts the Muncie EX Drive shaft extension. Call us to confirm proper fit and configuration for your application.
