The Muncie A20-A1007-XX1PBPW or A20A1007XX1PBPW is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible mounting, and the rotatable pump flange simplifies hydraulic plumbing. Tapered roller bearings extend service life, while an increased-diameter output shaft adds durability under load. The clutch pack design carries a single intermittent and continuous torque rating, removing guesswork from spec comparison. Three housing arrangements and extended-length PTO mounting fasteners give installers options in tight bays, and the unit is compatible with the EX Drive shaft extension. Call us to confirm proper fit for your application.
