The Muncie A20-A1006-JX5IIBX or A20A1006JX5IIBX is a medium-duty clutch shift power take-off from the A20 Series, engineered specifically for Allison 3000 and 4000 Series transmissions via a 10-bolt mounting. The shift cover rotates 360 degrees for flexible installation positioning, and the rotatable pump flange adds further mounting adaptability. A proven clutch pack design combines with tapered roller bearings to extend service life, while an increased output shaft diameter adds durability at the drive end. Gear geometry is optimized to reduce operating noise, and extended-length PTO mounting fasteners and reduced leak paths cut installation time. The unit is also compatible with the EX Drive shaft extension for added driveline reach. Call us to confirm proper fit for your application.
