The Muncie A20-A1010-SX11X or A20A1010SX11X is a medium-duty, clutch-shift power take-off from the Muncie A20 Series, designed specifically for Allison 3000 and 4000 Series automatic transmissions. The 10-bolt mounting pattern uses extended-length fasteners for a secure fit, and the shift cover rotates 360 degrees to accommodate different installation angles. A rotatable pump flange adds further flexibility during installation. Tapered roller bearings and an increased-diameter output shaft are built into the design to extend service life under sustained load. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the right configuration for your application.
