The Muncie A20-A1009-HX31XPXAP or A20A1009HX31XPXAP is a medium-duty, 10-bolt clutch shift power take-off from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees and the pump flange is rotatable, giving the installer flexibility in tight engine compartments. Tapered roller bearings extend service life, and the increased-diameter output shaft adds durability at the drive end. Gear geometry is optimized for quiet operation, and reduced leak paths cut maintenance calls. The unit accepts the EX Drive shaft extension and is available in three housing arrangements, with extended-length PTO mounting fasteners included. Call us to confirm proper fit for your application.
