The Muncie A20-A1008-SX11XPX or A20A1008SX11XPX is a medium-duty, 10-bolt clutch shift power take-off designed specifically for Allison 3000 and 4000 Series transmissions. The A20 Series uses a proven clutch pack design with tapered roller bearings to extend PTO service life, and an increased output shaft diameter for greater durability under load. The shift cover rotates 360 degrees and the pump flange is fully rotatable, giving installers the flexibility to position plumbing and controls without modifying the housing. Three housing arrangements are available within the series, and the unit accepts the EX Drive shaft extension for added application versatility. Extended-length PTO mounting fasteners and increased installation clearance simplify the swap. Call us to confirm proper fit for your application.
