The Muncie A20-A1008-HX51XBX or A20A1008HX51XBX is a medium-duty, 10-bolt clutch shift power take-off engineered specifically for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees, giving installers flexibility in tight spaces, and the extended-length PTO mounting fasteners along with increased component clearances simplify installation. A proven clutch pack design and tapered roller bearings keep the unit running reliably under load, while maximized gear geometry keeps operating noise down. The output shaft diameter is sized for added durability, and the rotatable pump flange accommodates multiple hydraulic configurations. Three housing arrangements and compatibility with the EX Drive shaft extension give fleet specs a range of installation options. Call us at Pro Gear and Transmission to confirm proper fit for your application.
