The Muncie A20-A1008-HX5PBBX or A20A1008HX5PBBX is a medium-duty, 10-bolt clutch shift power take-off designed for Allison 3000 and 4000 Series transmissions. It runs a 0.84:1 gear ratio with electric/hydraulic actuation, a straight mounting configuration, and a SAE BB 1"-15T output shaft. The shift cover rotates a full 360 degrees, and the rotatable pump flange simplifies installation in tight engine compartments. Tapered roller bearings and an increased-diameter output shaft extend service life, while a maximized gear profile and reduced leak paths address noise and fluid retention. Three housing arrangements and compatibility with the EX Drive shaft extension add flexibility for varied vocational setups. A genuine Muncie Power Products part from Pro Gear and Transmission.
