The Muncie A20-A1006-HX3PB or A20A1006HX3PB 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 to extend PTO service life, and an enlarged output shaft diameter for added durability under demanding cycles. The shift cover allows 360-degree rotation for flexible installation, and the rotatable pump flange simplifies hydraulic plumbing. Three housing arrangements give installers layout options, while extended-length PTO mounting fasteners and increased clearance reduce install time. The unit is also compatible with the EX Drive shaft extension. Call us to confirm proper fit for your specific transmission and application.
